Software Engineer, Package Management

Astral is revolutionizing the Python ecosystem by developing next-generation developer tools that enhance productivity and speed. The company is behind Ruff, a lightning-fast Python linter and formatter, and uv, an extremely fast Python package manager - both among the fastest-growing developer tools ever created.

The role focuses on uv, which has achieved remarkable success with tens of millions of monthly downloads and handles hundreds of millions of daily network requests to PyPI. This position offers a unique blend of technical challenges, from deep optimization work to user experience design. You'll work with SAT solvers and shape the future of Python development.

The team includes impressive talent - creators of tools like ripgrep, bat, hyperfine, and maturin, as well as core contributors to Biome, Prefect, and CPython. Working at Astral means being part of an open-source-first culture, where you'll actively engage with the community, review pull requests, and help maintain our public-facing development approach.

The company embraces remote work across multiple time zones (UTC-7 to UTC+1) and maintains a strong collaborative culture through asynchronous communication. Team members meet twice yearly for week-long, in-person on-sites. The hiring process is thoughtfully designed to mirror actual work experiences, featuring a take-home project, technical presentations, and collaborative coding sessions, all without traditional live coding interviews.

This role is perfect for someone passionate about developer tools, open-source software, and creating high-performance solutions that impact millions of developers worldwide.
