Software Engineer, Astral

We are looking for an experienced software engineer to build next-generation programming language tooling. If you like writing high-performance Rust, it could be a good fit; if you like thinking about the future of programming, it could also be a good fit. Strong candidates tend to have deep experience with Rust, Python, open source, compilers, or developer tools - but few candidates are deep in all of these areas, and we’ve hired candidates without prior Rust or Python experience.

In this role, you will:

• Design and implement features in Astral’s existing open source projects (Ruff, uv, ty, and python-build-standalone, and more).
• Support Astral’s open source projects as a maintainer, triaging user issues, reviewing pull requests, and participating in community discussions.
• Evolve the Astral toolchain to accelerate development velocity at OpenAI.
• Build entirely new tools, in entirely different programming ecosystems, to power the future of agentic software development.

• 5+ years of professional engineering experience, excluding internships, in relevant engineering roles.
• High agency and comfort operating in a fast-moving environment, with strong ownership of security, reliability, and operational excellence.
• Strong developer empathy and communication skills, including experience maintaining open source projects.
• Exceptional systems engineering fundamentals and a track record of leading complex projects from ambiguous problem statements through to user impact.
• Proficiency in one or more system programming languages (like Rust).

The Astral team builds high-performance developer tools to power the future of programming, at OpenAI and beyond, including Ruff, uv, and ty. The Astral toolchain sees hundreds of millions of installs per month and powers hundreds of millions of package downloads per day for the Python ecosystem. As a team, we are building on those foundations to continue solving impactful tooling problems as programming evolves., OpenAI is an AI research and deployment company dedicated to ensuring that general-purpose artificial intelligence benefits all of humanity. We push the boundaries of the capabilities of AI systems and seek to safely deploy them to the world through our products. AI is an extremely powerful tool that must be created with safety and human needs at its core, and to achieve our mission, we must encompass and value the many different perspectives, voices, and experiences that form the full spectrum of humanity., At OpenAI, we believe artificial intelligence has the potential to help people solve immense global challenges, and we want the upside of AI to be widely shared. Join us in shaping the future of technology.
