About the role
TL;DR
Build a reference implementation of a full AI inference stack in Rust.
- •We're building a new Rust engineering team from scratch
- •greenfield software, with real scope to influence architecture, engineering practices, and direction from day one.
- •Key Responsibilities Build a reference implementation of a full AI inference stack in Rust, tuned to Fractile's custom hardware Write a Linux kernel driver in Rust Develop cloud-based tooling for data centre deployments Research the state of the art in AI inference and bring new ideas into the codebase Collaborate closely with hardware engineers in a true co-design loop Requirements Strong Rust skills
- •or senior-level experience in a systems language (C, C++) with demonstrable Rust proficiency via open source or personal projects Experience serving AI workloads (e.g. vLLM, SGLang, or Rust equivalents), OR deep systems-level experience in adjacent areas such as low-latency data movement, paging, caching, or real-time processing A solid background in computer science and the ability to read unfamiliar code, understand it quickly, and identify problem areas Comfort working autonomously in areas of ambiguity
- •you’ll often be the person making sense of a problem for the first time
