What are the responsibilities and job description for the Rust Software Engineer - Distributed Systems position at Alignerr?
Rust Software Engineer — Distributed Systems (AI Infrastructure)
About The Role
What if your Rust expertise could directly shape the infrastructure powering the next generation of AI? We're looking for a senior Rust engineer to build and optimize the distributed systems, data pipelines, and tooling that leading AI labs depend on — working on real production systems with real consequences.
This is a fully remote, flexible contract role. If you're the kind of engineer who gets satisfaction from writing safe, performant, correct code at scale — and you want that work to matter — this is the role for you.
