Senior Software Engineers

Join us in helping advance the next generation of AI models!

We are looking for experienced Software Engineers to contribute to a cutting-edge AI evaluation project. This project plays a key role in improving how frontier language models understand, reason about, and generate production-quality software. You'll evaluate AI-generated solutions through the lens of an experienced software engineer, helping shape the future of AI-assisted software development.

Project Timeline

• Project Duration: Approximately 1 week

• Expected Timeline: July 8–14

• Expected commitment: at least 10 hours

• Candidates must be located in US/Canada due to the need for real-time collaboration with the project team.
