Software Engineer - Python (San Francisco Company)

We're looking for strong full-stack IC engineers to join our team.
Specifically we're looking for people who have:

1. Worked at a company with less than 100 people, with a lot of responsibility (founding engineer or CTO for example)
2. Are very comfortable with a single stack (Typescript / Python / Go / Java). Preferably some experience with Typescript (specially backend)
3. Are a product, platform or ML engineer. We are not looking for people with CI/CD, infrastructure or data science as their primary experience. We prefer backend experience over frontend
4. Are able to think for yourself and solve hard technical problems without any ai assistance, but are also leveraging tools like Cursor everyday to speed up your development

What you will do

You will be building RL environments and sandboxes that will be used by major LLM labs like OpenAI and Anthropic to train their coding agents. For that, you will onboard to a different codebase every 1-1.5 months. You will understand the codebase completely and build RL environments on top of it.
These environments will be engineering tasks to do on top of the codebase alongside perfect mocking and testing for how well the task was performed. You will be creating mocks, tests, hacking around infrastructure and whatever else required to build these environments. You will also build tooling and agents that helps you and other engineers build these environments faster.

Why you should join us

1. You will be working with a deeply talented and dense team. Our founding team is the following: Navid was the second engineer at Cursor and part of the team that built Cursor Tab. Justus lead RL at Prime Intellect (an OS LLM research lab based in SF). Calvin scaled a company to $1.5M ARR and sold it for $9M previously.
2. Our aim is to build the most talent dense team of engineers in India. You will work with the most talented team you have ever worked with
3. You will be respected and treated as part of our core team. We're building an in-person office in Bangalore (would still accept exceptional engineers remotely), and you will be treated as part of our main team. For example, our founders will be in Bangalore setting this team up and we will be very hands-on.
4. Very competitive salary
5. We've raised $10M raised from General Catalyst alongside angels from Cursor, Open AI, Anthropic, Cognition, Google Deepmind and more
6. We are one of the fastest growing companies in San Francisco right now
