We're a consulting platform and marketplace.
On one side (demand), we help businesses (consultants, investors, and startups) find, connect, and learn from experts. On the other side (supply), we help make it easy for experts to get paid to share what they know.
Similar to Uber or Airbnb, things are simple on the surface: search, match, connect, and pay. But under the hood, there are fun and challenging engineering problems across search, discovery, recommendations, data, logistics, payments, and performance.
We're looking for an experienced backend engineer to help us solve them. The ideal candidate will likely be a generalist with a lean towards data platform or data engineering.
Our small, driven, curious, and collaborative team has taken things from 0 to 1. If you're interested in helping us scale from 1 to 100 (and beyond), shoot me a note.

We’re building SMB accounting software API-first so that it can be integrated directly into software platforms where business owners already work. Our customers are vertical software platforms in the vein of Toast, MindBody or Housecall Pro that help small business owners start, run and scale their business with workflows and financial products. We help them serve their customers who are stuck exporting all their data out of these systems into CSVs and importing it back into other accounting software.
Integrating with our accounting APIs gives business owners automation & accounting workflows directly within their core software while the software platforms get to solve one their customers’ biggest pain points: worrying about bookkeeping & finances.
We’re looking for a founding frontend engineer who is excited about building a company and team as well as building better software for SMBs. We have no standalone frontend - instead we build a React component library that our customers can directly use within their own apps: https://www.npmjs.com/package/@layerfi/components

We're building a new, regulated, commodity market for large scale GPU clusters. More like the Kalshi, less like craigslist. To accomplish this, we make a VM orchestrator called "Fog" that understands InfiniBand, GPUs, and heterogeneous hardware setups.
We make money by taking a flat fee of a few cents per GPU hour upon delivery. Up until recently, we've been "running a market" via a spreadsheet, by selling bursts on very large clusters (think 6 to 8 figures deal sizes).
SFC started because Alex (https://alexgajewski.org/) & I went to go train an audio model and none of the vendors at the time would sell us a month-long contract. So we bought a year-long one, and tried to sublease it at cost (https://news.ycombinator.com/item?id=36933603), so that way we could buy just one month.
The goal of the company is the same: we want to make it possible to buy a big, giant training cluster for a short time period. We think a liquid market will let you spend $40m for a month instead of $300m for a year. If we can't make that happen, then only the big labs will get to make AI.
Most of our code is in rust, some typescript. We're about ~20 people. We raised $12m a bit ago. There are 7 ex-founders on the team.
We'd love to work with you! I'll bet you're cool.

We are Stack Auth, the open-source Auth0 alternative. We are looking for cracked engineers who are passionate about building for other devs, whether that's authentication or not. We think that there's too much overhead in starting and growing new projects; we're here to fix that.
We spend a lot of time thinking about how we can maintain the agility of a startup while being as reliable as larger incumbents. Sometimes, this means being innovative; for example, for our frontend and E2E tests we heavily rely on AI/RPA and snapshots, and have API migration tooling that blows everyone else out of the water.
A lot of the work we do is very close to databases and infrastructure, both with the problems we face at scale and the integrations we build for our customers. We are well-funded and backed by YC, Paul Graham, Guillermo Rauch, Khosla Ventures, and more.

Loop is on a mission to unlock profits trapped in the supply chain (https://www.loop.com/article/unlock-profit-trapped-in-your-s...) and lower costs for consumers. Bad data and inefficient workflows create friction that limits working capital and raises costs for every supply chain stakeholder.
Loop’s modern transportation cost management platform uses our domain-driven AI to harness the complexity of supply chain data and documentation. We improve transportation spend visibility so companies can control their costs and power profit. That is why industry leaders like J.P. Morgan Chase, ABB, Estee Lauder, Great Dane, Emerge, and Loadsmart, work with Loop.

We're building Instant - a modern Firebase. Instant gives you a database you can subscribe to directly in the browser. You write relational queries in the shape of the data you want and we handle all the data fetching, reactivity, permission checking, offline caching, and optimistic updates.
Some context on us:
In August we open sourced Instant and had one of the largest Show HN’s for a YC company. We just announced a $3.4M seed and are backed by James Tamplin (CEO of Firebase), Paul Graham, Karri Saarinen, Greg Brockman, Jeff Dean, Amjad Masad and a bunch more technical angels.
We're currently a team of 3, working in-person in our office in SOMA. Our backend is in clojure and our frontend is typescript. We all do a bit of everything :)
We're looking to grow our team to 5. If you're the kind of hacker who who takes their craft and their word seriously, who moves fast, and isn’t afraid to look into the ‘scarier’ parts of programming, we want to talk to you
Want to apply?
Send us an email at founders [at] instantdb.com . Please include a side-project you've worked on (if it comes with a GitHub, heeck yeah!).

Roboflow is the fastest way to use computer vision in production. We help developers give their software the sense of sight. Our end-to-end platform[1] provides tooling for image collection, annotation, dataset exploration and curation, training, and deployment.
Over 250k engineers (including engineers from 2/3 Fortune 100 companies) build with Roboflow. We now host the largest collection of open source computer vision datasets and pre-trained models[2]. We are pushing forward the CV ecosystem with open source projects like Autodistill[3] and Supervision[4]. And we've built one of the most comprehensive resources for software engineers to learn to use computer vision with our popular blog[5] and YouTube channel[6].
We have several openings available but are primarily looking for strong technical generalists who want to help us democratize computer vision and like to wear many hats and have an outsized impact. 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 full-stack engineers for our ML and web platform teams, a web developer to bridge our product and marketing teams, several technical roles on the sales & field engineering teams, and our first applied machine learning researcher to help push forward the state of the art in computer vision.
