Job description

This growing startup uses Rust, Python, and TypeScript to deliver health-tech services. As a small team, everyone contributes to a range of areas with the goal of meeting end user needs.

In particular, this role will focus on developing audio and video streaming via WebRTC, alongside other high-performance and some low-level systems.

Your experience will include:

1. Kernel-level (or close to) software engineering in Rust, C, C++, or low-level functional programming languages such as OCaml.
2. Extensive software engineering using Python, as well as experience with one of the above languages, and an interest in Rust as a primary development language.
3. Familiarity with multi-threaded code and OS-level I/O primitives in Linux.
4. Significant experience developing commercial-grade web application platforms—ideally for video streaming or similar high-throughput systems—or working on compiler technology for programming languages or DSLs, as both are valuable here.
5. Startup experience or a strong interest in working as part of a small, fast-moving team.

Work is primarily office-based in rural west Cambridge, within easy reach of the city. A day per week can be work-from-home, with some additional days over the year. Benefits include salary, share options, and healthcare. Full UK work permission without sponsorship is required.

Keywords: Rust, Python, video, audio, WebRTC, Linux, kernel, I/O, multithreading, compiler, DSL
