The Role

As a software engineer, you will execute on our vision to create RL environments to automate software engineering. In particular, you will:

• Design realistic evaluation scenarios: Independently identify meaningful software engineering tasks, determine clear grading criteria, and select the appropriate tools and workflows that allow AI agents to complete tasks.
• Influence technical direction: Directly shape product development, make key architectural decisions, and contribute to growing our engineering team at an early-stage startup.

You might be a good fit if you:

• Are about to graduate university, or have 1-5 years of experience building software products
• Write fluent Python
• Have practical experience with designing CI/CD processes

We encourage you to apply even if you do not believe you meet every single qualification.

No prior machine learning or AI experience is required.
