Accretional | Founding Software Engineer | San Francisco, ONSITE | Full-Time | $100k-200k + 1-2+% equity

Come work with us on Brilliant, the most capable agentic AI code editor to date. We're putting the finishing touches on it - join us and help us ship!

We're looking for someone with frontend / fullstack skills, with at least 3 and preferably 5 or more years of experience. It would be beneficial to have additional experience with any of the following: IDE and IDE extension development, cloud development environments, platform engineering, AWS/GCP/K8s/containers, devops, WASM, "prompt engineering", and of course LLM usage and development. Skill with wielding AI dev tools as a user would be a very big plus.

We're located in Jackson Square in San Francisco, and this role would be on-site four days per week. We cannot sponsor visas at this time, and you should either be in the SF Bay Area already or able to relocate here by the end of January.

About Accretional - I [0] left Google in March to better integrate LLMs into developers' workflows. I though most products and startups in the space were either being way too ambitious with what they were claiming to build, or building things that weren't adding much more value than just integrating a chat interface. I still think that. Brilliant is our first product, and we have more to come. I'm the founder, we have one full time employee, and a couple part time employees. You'll have the opportunity to join us very early on with all the excitement and hat wearing that entails!

Contact: jobs at accretional dot com [1]. Please add a brief description of how you currently use AI dev tools.

[1] You might notice if you visit our website that it kind of sucks. That's why we need someone like you with frontend skills! Brilliant itself is in a better shape, but we really need a frontend expert to help us make it something our users will love.

Gain Compliance | Sr Software Engineer | Remote (USA) | Full-time | ~$160k | https://join.gaincompliance.com

Hey this is Brian from Gain Compliance, we've had success hiring out of a hacker news thread before, so let's give it a spin again.

We are a small company that builds financial reporting tools for the insurance industry. While the domain might be foreign to most, we are having a lot of fun building modern web software with React, Python and Node running on GCP infrastructure. You'll be joining 7 other engineers split into two full stack product focused teams.

We've been around over 8 years and value empowering our customers to breeze through their boring compliance tasks, building great teams that focus on outcomes over features, and work place stability.

We wrote a lot more over at https://join.gaincompliance.com if you are interested.

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've scaled to >$3MM annual revenue and 400k MAU with our small team. 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 more of a 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.

Purplefish | https://purplefish.com/careers | Member of Technical Staff | Full-Time | ONSITE | New York, NY, USA | NextJS, Typescript, Python | $150k-$225k + 0.5%-1%+

Purplefish is transforming the trillion-dollar talent industry with powerful AI agents that will fully automate most hiring processes end-to-end.

We are funded by 8VC, and Adam and I previously worked closely together to launch 145 companies at the venture studio Fractal Software out of a $650 million fund. Before that I was a staff software engineer at Lyft, and Adam was CRO at Wunderkind ($100m+ ARR). We've built a powerful voice agent, and are expanding into other parts of the sourcing-to-onboarding flow.

We're currently a team of 3 engineers in NYC (7 people total). We're working on really cool problems with multimodal AI agents (and some really not cool problems like ATS and HRIS integrations). I'm trying to build the engineering team that I would want to join, which to me means a high emphasis on agency, purpose, technical excellence, collaboration, learning and velocity.

We're building on LiveKit's agents framework and a host of other systems.

If that's interesting, let's talk.

Sequin | Platform Engineer | San Francisco | ONSITE

We're building the world's fastest change data capture (CDC) platform for Postgres. CDC is a proven pattern that enables real-time use cases like triggering side effects, fanning out events, caching at the edge, and audit logging - but existing solutions are notoriously difficult to set up and maintain.

We're making CDC easy enough for weekend projects yet robust enough for Fortune 500 companies.

Sequin is open source/MIT (https://github.com/sequinstream/sequin). We're backed by Kleiner Perkins and Craft Ventures.

Tech Stack: Elixir/Phoenix, LiveView + Svelte, Postgres

What makes this role exciting:

- Join an early-stage open source project with significant technical influence

- Build a tool you would use for a user you understand

- Work deeply with Postgres

- Solve novel distributed systems challenges (not building CRUD apps)

- Work with Elixir/Phoenix and OTP primitives in production

- High-energy environment focused on rapid iteration and customer impact–we ship a lot, and fast!

We're based in San Francisco, where we have an office. Learn more: https://sequin.notion.site/

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.
