Remote, Global

We’ve partnered with a YC-backed AI tooling startup to find an Open Source Software Engineer who’s passionate about building developer tools for the LLM era.

The company is developing a widely adopted, open-source framework for evaluating LLM applications, which is already used by engineers at top companies such as Google, Amazon, and Databricks.

As part of a small and focused team, you’ll work on a high-impact library that’s shaping how the next generation of AI products gets evaluated and improved.

What You'll Do

• Build new features that improve how developers evaluate LLM-powered applications.
• Contribute to the design, maintenance, and evolution of the open-source library
• Collaborate with the community- responding to issues, feature requests, and bug reports
• Work closely with users to improve the developer experience

You Might Be a Fit If You

• Love working on open-source projects and care about the developer experience
• Have strong experience with Python and software engineering best practices
• Have contributed to open-source libraries or maintained your own projects
• Enjoy startup environments and thrive in ambiguity

Bonus Points

• Prior work on evaluation, RAG workflows, or LLM-based applications
• Contributions to AI infra or tooling libraries used by other developers
