Elicit | San Francisco + remote (US timezones) | https://elicit.com/careers

Elicit is an AI research assistant that uses language models to help researchers figure out what’s true and make better decisions. We scaled to >$5MM annual revenue and 450k MAU fast. We're hiring for multiple roles and are primarily interested in people with early-stage company experience, who are comfortable in high-agency, fast-paced teams.

Reasons you might want to join Elicit:

1. We have been thinking about how to apply AI for high-stakes knowledge work since even before GPT-1. Elicit was spun-out from Ought (https://ought.org/) which was an applied research lab.

2. If you're concerned about the potential downsides and risks of super-powerful AI: so are we! Happy to explain more of this story on a call, or you can also check e.g. https://ought.org/updates/2022-04-06-process for a primer.

3. We like spending time with each other, and have get-togethers every 6 weeks, but we're flexible on location.

Reasons you might not want to join Elicit:

1. We've found a level of product market fit (as evidenced by metrics) but we've not proven everything out yet. If you want predictability, Elicit is not for you.

2. We aim to hire people who thrive in low-bureaucracy environments, and let them loose. If you need structure, lots of support, close mentorship, or tightly-defined work assignments, Elicit is not for you.

Waterlily | Multiple Roles, see below | Remote (with option to be hybrid in San Francisco, CA) | Full-time | www.waterlily.com

Waterlily uses advanced AI to tackle one of the biggest, unsolved challenges in retirement planning: long-term care (LTC). We have already closed enterprise deals with multiple Fortune 100 insurance carriers and distributors, and raised an oversubscribed $7m Seed round from backers such as Insight Partners, Nationwide, Edward Jones, Brewer Lane Ventures, and Genworth. Our mission is to help families proactively plan for LTC needs and costs, and reduce America's multi-trillion-dollar LTC crisis.

We have extremely high standards and expect our team to move quickly while maintaining top quality. Our interview process is rigorous, and most applicants will not pass. Those who do join a small, highly skilled team working directly with our founders (who started college at ages 11 and 14, attended UC Berkeley and MIT, and have built and sold successful startups backed by Founders Fund and Khosla Ventures before). We value rapid learning, candid feedback, and intense execution. We all invest more than 50 hours a week, sometimes up to 80, when needed to achieve top-tier outcomes. We want people who thrive in that environment, with the maturity to also pace themselves for sustainability.

Open Roles

Full-Stack Engineer

MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time

MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security.

We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome.

We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team.

Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.

We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.

We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

Tandem Health | Software Engineers | On-site in Stockholm, Sweden | Full time

At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and already have more than 300 organizations using our product.

Our core product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. No longer do clinicians have to catch up on administration after hours. Some even tell us that their partners notice they're much more relaxed after starting to use our product, and we couldn't be happier :)

We're expanding our Stockholm team with exceptional engineers! We use Python (backend), TypeScript/React (frontend) and C# (Windows app) and our infrastructure runs on Kubernetes in Azure. We're scaling rapidly in terms of # of users and are especially keen to talk to senior backend engineers who have helped startups scale from thousands to millions of users.

Even if we don’t have a role out for your specific skill set, we’d love to talk! Our tech team is small but growing and you’ll have an outsized impact on an important problem.

FinQuery | AI Engineer | REMOTE (US) or Atlanta, GA | Full-time

I'm hiring an AI/ML engineer to join the AI/ML team at FinQuery.

Our team creates services powered by LLMs and traditional ML to enable features across our suite of products. Like many companies, we are trying to separate the real value of the latest AI techniques and tools from the hype (agents?), and unlocking use cases that actually benefit our customers. This role is a rather generalist role for someone with a strong ML background, 2+ years of work experience (post schooling), and a desire to work on both proof of concept and production systems. You would be joining our small AI/ML team as we continue to automate as much as possible and enable new product features and use cases.

FinQuery makes software to help companies comply with new lease accounting regulations, manage financial contracts, and keep track of recurring and one-off payments. We're based in Atlanta, but support fully remote employees in the US. This is an IC role.

https://finquery.com/careers/

We are also hiring for roles in DevOps, marketing, and more.

We have lots of people wanting to get involved in the project, and so we plan to open the project up to anyone to contribute, whether they be public media, private media, institutions, universities, or enthusiasts. To make that work well, we want to hire an open source engineer who can manage contributions, create training materials, do refactoring, manage forums, and do all the other things necessary to nurture a healthy open source community.

Particularly interested in people with experience maintaining Open Source projects and working with outside contributors.

Our mission at Surge is to build the human infrastructure behind the next wave of AI and LLMs. We operate a data platform that powers AI teams at OpenAI, Anthropic, Meta, Google, and more. This year, we're focused on extending our platform to support agentic workflows and help our clients ship agents that interact with the world. Here are some examples of our past work:

- Creating the GSM8K dataset: https://www.surgehq.ai/blog/how-we-built-it-openais-gsm8k-da...

- Collecting RLHF data for Anthropic's Claude: https://www.surgehq.ai/case-studies/anthropic-claude-surgeai...

You’d be joining a small, rapidly growing team of former engineering and ML leaders from Google, Meta, Twitter, and Airbnb. We work in small groups, ship quickly, and value autonomy and ownership. No previous AI experience is required, if you have the engineering skills you can learn what you need on the job.

We're looking for senior engineers to work out of our offices in SF or NYC, or remotely. Please reach out to us at careers@surgehq.ai with a resume and 2-3 sentences describing your interest. Excited to hear from you!

Rock Rabbit | Backend Engineer | Full-time | USA FULLY REMOTE

Buildings account for ~40% of all emissions. There is a ton of federal, state, and local programs to help decarbonize buildings -- but this money is difficult to access, trapped behind complicated program requirements, uncertain eligibility, lack of clarity, and long payout cycles. We make access to these incentives easy by abstracting away the policy complexity and letting our users focus on their projects. Our platform serves contractors, homeowners, incentive providers and implementers, and equipment manufacturers.

We're hiring Backend Engineers for full time roles.

We're well-funded, have a lot of customer traction, and are rapidly expanding the team. Our product vision is very clear -- the bottleneck is skillful, user-focused execution.

Tech stack: Python (FastAPI, pyright), Google Cloud (GKE), React (Typescript, react-query, auto-gen API client)

We value curiosity, ownership and collaboration. Interest in energy, climate, and sustainability is a plus.

AO Labs | real-time reinforcement learning | https://www.aolabs.ai/ | SF, CA + remote

AO Labs is an applied AI research lab building real-time reinforcement learning, unlocking AI that can be hyper-personalized with less data than LLMs.

Our first product is an API that learns by combining end-user context, application data, and a feedback signal (eg. an end-users' likes and dislikes) in a fast learning loop that's lightweight enough to provision a distinct agent per-user. There's no gap between training and inference-- train at the edge, learn all the time.

With our framework we increase training efficiency and also combine the static pre-trained intelligence from LLMs with continuous training to learn local contexts. AI progress is bottlenecked by backpropagation, which necessitates labelled data to set the ground truth while also leaving a gap between training and inference that result in increasingly larger, more homogenizing models.

We are hiring for applied researchers & various engineering roles– please reach out to ali@aolabs.ai

Layer | Full stack & Backend Engineering | San Francisco | https://layerfi.com

We believe SMBs are the backbone of American society and small business ownership is the best path to wealth creation and economic mobility for many Americans. We're trying to dramatically lower the activation energy in just one of the major hurdles for aspiring small business owners: accounting and bookkeeping.

Our approach is working! We embed directly within an SMB's primary business platform, manage all the data syncing & reconciliation for them, and have real humans (with real AI tooling) handling their books. We do this at ~half the cost of existing bookkeeping services and it's still profitable for us because we're saving so much time with our data access + AI.

Adoption is taking off faster even faster than we hoped and we need to grow the team! We're a team of 5 who like working with a high ownership and high throughput collaboration. We have serious technical challenges across scaling systems, data modeling, and building AI-driven automations of tedious tasks.

Our hiring philosophy is simple.

1. The early engineering team isn't just building products, it's setting the culture, practices, and standards for the whole org. Find teammates who have the appetite and agency to go beyond excellent code.

2. No one knows more than 10% of what they need to be successful at an early stage startup. Find teammates with the highest trajectory of learning and growth and give them as much opportunity and responsibility as they want.

3. We talk to real small businesses with real problems every single day. Find teammates who want to win by making our customers successful day in and day out.

In just five months, we've built notetaking/scribing, Clinical Decision Support, and some of the integrations a clinician needs to run their practice with Vibrant as their AI Operating System.

In words of our customers: "I have goosebumps, this is really incredible. Very accurate." "Seeing the patient overview AI-generated summary come to life after placing a couple notes is AMAZING. I'm losing it over here"

Our stack: Typescript, React, NextJS, React Native, Expo, and custom AI agents, RAG, tools, and agentic workflows.

Seeking a hands-on, visionary CTO & Co-founder to architect our system (AI, distributed systems, data, infra), build the founding engineering team, and drive technical strategy. This involves deep work in multi-agent systems, collective learning, secure execution, and potentially novel consensus/incentive mechanisms.

Must have: Proven leadership in AI infra (CTO/VP/Founder/Lead Scientist). Expertise in GenAI/RL/DL/MLOps/PyTorch. Experience with agent frameworks (LangGraph, AutoGen, etc.) and distributed/federated AI concepts. MSc required, PhD strongly preferred. Strategic thinker passionate about building developer ecosystems.

Nice to have: Blockchain/Web3/tokenomics experience.

Attendi | Senior Frontend-Focused Full-Stack Engineer | Amsterdam, ON-SITE hybrid | Full-time (80-100%)

Healthcare professionals have to spend too much time on administrative tasks when they should be spending that time delivering great care. Attendi allows healthcare professionals to report with their voice. This saves them precious time and removes the screen between client and caregiver, allowing more personal and effective care to be given. Burdened by an aging population, the healthcare sector is in desperate need of innovators like Attendi. We feel that we provide an extraordinary work environment: getting paid well to work with smart people on things that actually have a positive impact on society.

Attendi has built a strong user base with its API-first speech-to-text solutions and client SDKs, loved by healthcare professionals via integrations with electronic health record (EHR) vendors. Currently, users interact with our products only within their EHR systems — but why stop there? We want to enable them to benefit from our tools anytime, anywhere.

As a Frontend-Focused Full-Stack Engineer, you’ll play a key role in developing our new (greenfield) products to support this ambition:

Attendi’s first external full-stack app — which we see as the healthcare sector’s notepad. Our aim is to make it the default write-layer for medical data. But it’s far more than a simple notepad: speech-to-text and machine learning will be deeply integrated.

We have a dedicated team with fewer than 25 members, which means no bullshit, moving fast, and getting a generous slice of equity. We're post product-market fit, profitable, and on the cusp of scaling up in the Dutch market.

Check out https://attendi.recruitee.com/o/senior-frontend-engineer-web for more details on the position.

Feel free to send any questions to berend [at] attendi [dot] nl.

Iterum | ONSITE/HYBRID (London, UK) | Full time | https://iterum.uk

Iterum is a seed-stage startup revolutionising appliance management for scaled residential properties. Our platform, Iterum IQ, is addressing a critical but overlooked challenge in property management: the inefficient handling of home appliances and consequential lack of actionable data. These things together lead to significant costs, wasted time, and increased carbon emissions. Our mission is to streamline appliance procurement and management, delivering substantial cost savings for property operators and investors, enhancing resident experiences, and reducing carbon footprints at scale.

We’re looking for a talented and ambitious mid level (at least 3-5 years experience) full stack developer to join as our Engineering Lead. You’d work with me - the (fractional) CTO - as well as the (full time) Head of Product and the rest of the team to get Iterum IQ from MVP to scale.

Our tech stack is Django with SSR, PostgreSQL, Bootstrap, HTMX, and a couple of other tools and services. You should be familiar with Django and strong on the backend side, at least competent on the (web) frontend side and with (cloud, at this point) infrastructure management. We’re a small team, so you’d work on pretty much everything.

You’d need to already be based in or near London. The job is onsite, though hybrid is fine.

Gridmatic | Senior fullstack software engineer, Senior backend software engineer (ML infra) | Full-time | Hybrid (Cupertino, CA)

Gridmatic uses ML and weather data to forecast energy prices in the US, which can get really volatile as extreme weather becomes more common with climate change. We’ve been using those price forecasts to e.g. optimize very large batteries, which help make the grid more stable.

On the fullstack side, we're building tools to apply our forecasts to automated battery storage optimization and energy volatility risk mitigation. On the ML infra side, we're working on infra to be able to scale to larger and more complex models, and to apply better (but more computationally intensive) weather models in our forecasting.

Our stack: python, react/nextjs, kubernetes, GCP, postgres, bigquery

Our goal is to help accelerate the adoption of renewable energy on the grid. It's super interesting, the team is incredibly smart, and we're profitable.

If you're interested, DM me or email me at kevin@gridmatic.com, and please answer the following question: what's the most impressive thing you've built? (include a link to code if possible)

We're bootstrapped and profitable, with a small, smart, friendly and diverse team.

Building dev tools is great! We're solving problems we've experienced ourselves, our customers are developers just like us, and platforms have the most fun engineering problems.

FusionAuth | Senior Java Software Engineer, Senior Security Engineer | Denver, CO, USA ONSITE | Salaries listed on job req, but for the Java engineer it is 140k-180k

Our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome.

There are a lot of companies in the auth space, but we feel like we have something special:

* a unique deployment model (self-host on-prem or in your cloud or run in our cloud)

* A well designed API first approach; one customer compared our app to petrichor

* a relatively mature product (the code base is over eight years old and we've found and fixed a lot of the sharp edges around core login use cases; however there are plenty more features to add)

* founder-led; the CEO is an engineer who still writes code

* a full featured free-as-in-beer version that makes the sales cycle easier; prospects often come in having prototyped an integration already

If you are passionate about technology and want to join a company moving the industry forward, FusionAuth might be a great fit for you. As mentioned, our core software is commercial with a "free as in beer" version. We also open source much of our supporting infrastructure.

We are profitable but raised a round in 2023 to accelerate our growth (more on that here: https://fusionauth.io/blog/fusionauth-funding ).

Technologies and standards that we use or implement: Modern Java, MySQL, PostgreSQL, Docker, Kubernetes, OAuth, SAML, OIDC.

Stealth AI Healthcare Startup | Boston, MA Onsite | Full-time | Founding Engineer

We're looking for a backend-leaning fullstack dev. You will be the first engineer outside of the founding team. Here is a bit more about us:

We're a seed stage AI startup backed by several top tier VCs.

We're on a mission to ensure patients get the coverage they deserve and providers get paid fairly! To do so, we're debugging core problems in the US healthcare system with a modern tech stack and AI. We use AWS, K8s, React, and Rust but there is no requirement to have prior experience with them specifically. We'll teach you!

We are a founding team made up of ex-YC, Amazon, Meta, and Harvard Business School with previous successful exits. We also have a 6+ month customer waitlist!

We're hiring our first engineer outside the founders. You'll work directly with customers to understand their needs, design the right solution, and build from zero to one. You'll own entire parts of the roadmap and tech stack while wearing multiple hats. Most important characteristics are resilience, work ethic, and curiosity. We care about slope, not where you are today. This is an opportunity to work in an insanely fast paced, high ownership environment while solving real problems in healthcare.

We're happy to share more details on the role in person/on zoom. Please fill out this form if interested!

Narrative I/O | Senior/Staff Backend Engineer - Query Compiler | New York, NY | Full-time | REMOTE | $140k to $200k USD | https://narrative.io/

Narrative has been building a data collaboration platform designed for simplicity and ease of use since being founded in 2016.

Our primary strength is functioning as a data marketplace where we differentiate ourselves by:

- Automatically standardizing data, simplifying the user experience by eliminating the need to deal with n representations of the same underlying concept from different suppliers.

- Making platform data accessible through the Narrative Query Language (NQL) and easy-to-use UIs powered by NQL. This enables users to transform, deduplicate, and filter data instead of selecting from a set of provider-defined, pre-packaged datasets.

- Giving data providers the ability to define row-level access and pricing policies for their data.

We are a small, remote-first team looking for someone with experience working on query compilers or query execution systems in general. While the company's headquarters are in NYC, the development team currently includes engineers working from the US (California and New York), Canada (Alberta, British Columbia, and Québec), Poland, and Serbia.

In brief, the technologies we use are:

- Scala, Spark, Apache Iceberg, Apache Calcite, Cats, Cats-Effect, Http4s, FS2, Doobie, Deequ, Axolotl, BentoML, and HuggingFace Transformers. We love functional programming and make use of libraries like Cats, Cats-Effect, and FS2, but we keep a pragmatic stance on purity given our exposure to the Spark ecosystem.

- Our services are deployed on AWS and provisioned using Terraform. We leverage the usual suspects: Fargate, EMR, RDS, Lambda, etc. and we're starting to lean into Kubernetes. Being a small team, we think twice before rolling out custom infrastructure that we'll need to monitor and maintain.

- On the frontend, we use Typescript, VueJS, PrimeVue, Nuxt, and Vite.

Job posting and more on information about our team and culture are available at: https://jobs.narrative.io/open-positions/backend-engineer-qu...

Tacton Systems | Multiple roles | Hybrid, Stockholm

Full stack Java, JavaScript / TypeScript

We make a Configure-Price-Quote SaaS for complex product portfolios. For example, one customer is Tetra Pak, that sells machines that build packaging (milk, juice, etc). These machines are like a two-story building with many variations, every aspect has to be well-defined and validated before it's ordered.

In our solution products can be modeled in detail with constraints, and during a sale options are chosen and validated, often visualized parametrically, pricing is done, and a quote is prepared. All based on the well-defined model.

It's a 30-year old company that started as a research startup, grew organically, and has a stable customer base. After a recent acquisition it's aiming to grow, therefore many positions are open. I started working here just a year ago, but I can say the work environment is healthy and relaxed, lots of competent people and everyone I interacted with so far have been very nice and professional.

Chorus One | https://chorus.one/careers | Platforms Engineer | REMOTE (Switzerland ± 6 hours)

Chorus One operates validators on many proof-of-stake blockchains (the ones where security is based on a Byzantine fault-tolerant consensus algorithm rather than wasting energy). We are hiring for several roles, but the one I will highlight is what we call Platforms Engineer. Some companies call this Site Reliability Engineering or Devops.

The main thing we do is take upstream software, build it, run it on our infrastructure, and then monitor it and optimize that setup. Some things that make this interesting are:

    * Building automation that enables us to do this for many networks (70+ currently).
    * Doing this with high uptime, building automation for failover, etc.
    * Working with software that is on the one hand cutting-edge and doing interesting things (consensus algorithms, distributed systems, cryptography), but on the other hand that means it’s immature and often not easy to operate and monitor. Often we have to build custom tools, and dive into the source code of the project. We contribute patches upstream when it makes sense.
    * Some of these projects are exercising the limits of what a machine can do, we have to do some low-level investigation that requires understanding of what the Linux kernel and network hardware are doing to properly identify what’s going on.

A recent example of what I personally find fascinating: last month Ethereum’s Holesky testnet experienced loss of liveness. This is a real-world, globally distributed system that implements Byzantine fault tolerance, with multiple independent implementations of the protocol. Several of these implementations had a bug in an update, which caused a split in the network. The protocol is designed to handle this situation in theory, but in practice it is triggering previously unexplored failure modes in the implementations, that are hard to test for in synthetic small-scale tests. I think there are very few places where you get to be involved in a planet-scale distributed system exhibiting “interesting” behavior, especially one that is not in control of a single entity. Of course, there is also the less fun part that the testnet was broken, alerts are firing, and it was hard and chaotic to coordinate a fix when the network is not controlled by a single entity. Fortunately it’s a testnet.

Sitch App | Engineer | NYC-area HYBRID (2 days/week in Brooklyn) | Full-time | Python + Django + Flutter + Rust Sitch is a new type of concierge dating app. We're using AI + Humans to ask you questions, get to know you, then help you find love. We're a concierge matchmaker but we don't call ourselves that and we don't charge the obscene prices that matchmakers charge.

One of our metrics is how little time you spend in the app. We're explicitly opposed to the dopamine-fueled mini-game doomswiping of 'traditional' dating apps which cynically monetizes desperation. We're monetizing intent!

* We're top-tier VC funded, small team of 2 cofounders (Snapchat, Bumble), a CTO from Snap/Clubhouse, and 3 engineers, based in NYC.

* Stack is Django, OpenAI, Flutter, Rust

* Looking for a Mid-level Engineer who is an all-arounder. Backend more important than front-end code, but if can also work on client code (or want to learn) that would be ideal.

* 1-2 days/week in person, in Brooklyn, and the rest remote. We strongly prefer NYC area candidates.

Looking for my Shel Kaphan | Dirac | Lead Founding Engineer | 5% equity + £70k base (£100k base after series A) | London, Acton | in-person only

Dirac is building the next Walmart-sized retail company over 10+ years. We sell d2c and are doing £300k-£500k monthly sales (lots of toys and reasonably seasonal). I built most the initial systems which run the company’s backend (purchasing, databases, pipelines etc.) but we will need something (and someone!) better to reach £1bn+ sales over the next four years

We need to go from a bunch of bash scripts coordinated by systemd, adhoc estimators and pipelines to a more coherent machine for demand estimation, matching products, warehousing and purchasing.

You’ll be mostly writing code (django+postgre+a hetzner server) but also helping our two more junior devs.

The vision for the company is twofold: (1) find 1000s of suppliers and wholesalers worldwide and (2) to ingest all their pricing, logistics and then move stock to where prices and demand is highest.

Visa sponsorship possible.

Investors include will thorndike, charlie songhurst, patio11, backedvc and some others!

Purple Dot | 1x Senior Full Stack Engineer (London, UK) + 1x Customer Solutions Engineer (New York, US) | 2 days/week in office | Full-time

At Purple Dot, we are on a mission to create a world where, ultimately, every product that is manufactured is sold. The current e-commerce model leaves brands waiting for stock to arrive at the warehouse before they can start selling, leading to missed sales opportunities, unsold inventory and waste. We believe the next wave of innovation will happen in the time before stock arrives, enabling brands to sell inventory no matter where it is in the world. Our pre-commerce platform puts the power back in brands’ hands, allowing them to take control of their sales timelines and maximise revenue potential.

And we make pre-orders trust worthy for the shoppers too, keeping their money in escrow until items ship, and always up to date on where their pre-order is at, with an option to cancel no questions asked.

We've raised a $10m Series A in 2024, we've plenty of runway left and we're looking for help as we scale our platform through the next order of magnitude in terms of load on the system and ultimately the number of dollars we process.

We are a team of 22 split evenly between the UK and US. 32% female, including the CEO. All of us have a mix of startup and big tech experience. For the founding team this is our second (so far :) successful startup.

I have two engineering roles open:

* senior full stack engineer - based in London, UK - to join our core engineering team of 6 that are shipping our product roadmap: https://purpledot.notion.site/senior-full-stack-engineer-uk

* customer solutions engineer - based in New York, US - to work with our support and sales teams to help make going live with and using Purple Dot a delightful experience for brands and their shoppers: https://purpledot.notion.site/customer-solutions-engineer-us...

Like everything else we do, we interview fast, and you will deal with me (head of engineering) throughout.

https://center.app | Center Pixel, Inc | Engineering | Full-time | Remote | 100k+ and up (we are flexible on salary since we're venture-backed and still a 4-person team) We build web3 developer tools and are most focused on solving the "schlep" types of problems that every team ends up building in house but shouldn't have to. Building stuff in crypto today is really hard. Imagine if you wanted to put up a personal website and all you had to do was start by breaking ground to build a data center. Your personal page probably would not be that good, would it? Small teams can only focus on so many things; we want them to use center so they can focus on the details that truly matter and make products beautiful.

We want to eliminate all of these annoying, cumbersome, expensive problems that devs face so that they can build incredible user experiences that help people flourish and rise to the level of their ambition, without having to think about if their nodes are online or if their indexer is missing any data.

We started about 3 years ago and have finally started to find product market fit. We're looking to scale the engineering team so that we can finally bring our products to market.

Our investors include Founders Fund, Thrive Capital, SV Angel, @balajis, and many more incredible folks who have taken a chance on us; it's been my mission for the last 3+ years to make sure that everyone involved in this venture does phenomenally well.

Our engineering culture is built on a foundation of autonomy & we don't consider an engineer fully ramped until they can "choose their own loss function". At Roboflow, engineers aren't just responsible for building things but also for helping us figure out what we should build next. We're builders & problem solvers; not just coders. (For this reason we also especially love hiring past and future founders.)

We're currently hiring for full-stack engineers to help build our product, field engineers that work directly with our customers to solve their business needs with computer vision, and several technical roles on the sales team.

We just raised our Series B round, led by GV. With this round, we will continue building the open source tools, platform, and community so developers and enterprises can deploy computer vision applications to production. [7]
