Rust Engineer (AI Training)
About the Role
What if your deep knowledge of Rust — memory safety, concurrency, systems performance — could directly influence how the next generation of AI understands and writes systems-level code?
We're looking for experienced Rust engineers to work alongside leading AI research teams, evaluating and improving AI-generated Rust code, building high-performance tooling, and helping ensure that AI systems produce code that's safe, correct, and production-ready.
This is a fully remote, flexible contract role built for senior engineers who want meaningful, technically stimulating work on their own schedule.
- Organization: Alignerr - Type: Hourly Contract - Location: Remote - Commitment: 10–40 hours/week
