Posted January 15, 2019


Y Combinator has a small ~4 person team that makes the software that runs YC. Software is a critical part of YC - we see it as key to our future and we are investing aggressively in new software products.

YC has ambitious plans to create more innovation in the world, and the only way to reach that level of impact is to scale through software. What we’ve built so far is probably only 10% of what we will eventually need.

Some of the things we've worked on recently are Work at a Startup, Startup School or this technical blog post. You can read about the daily life at YC, the people on our team, and how we work together on our Key Values page.

As a member of the software team, you'll get full access to the YC program, just like founders do. You'll learn the ins and outs of how YC works, and you'll get to know and learn from hundreds of companies. You'll meet some of the most successful people in the startup world and get exposed to the best startup ideas. If you ever want to start your own company, working at YC would be an excellent jumping off point.


We're looking for capable generalist engineers. We care mostly about your ability to write great software; we don’t care if you’ve used the technologies we work with as long as you’re willing to learn them. Because we don’t have product managers, we look for engineers with great product instincts who can own whole projects from start to finish.

This is a good job for a someone who is excited about startups and interested in learning more about them. You’ve likely worked at or started a startup, or want to do so in the future.

We generally look for people with at least two years of work experience. We usually aren't able to hire current students or recent graduates.

The software team has a lot of individual responsibility and access to sensitive information, so we need to hire people we can trust. Your ability to make good trade-offs and exercise good judgement is particularly important to us.


The YC internal software is mostly written in Ruby on Rails and React. It runs on AWS and PostgreSQL. Previous experience developing web apps will be helpful, but we don't care if you've used React or Rails specifically.
