What are the responsibilities and job description for the Backend Rust Engineer position at Alignerr?
Backend Rust Engineer (AI Training)
About The Role
What if your deep expertise in Rust could directly shape how the next generation of AI understands systems-level programming? We're looking for experienced Rust engineers to review, evaluate, and challenge AI-generated code — helping ensure that the models influencing software development worldwide can reason correctly about memory safety, ownership, concurrency, and performance.
This is a fully remote, flexible contract role designed for seasoned Rust developers who know what good systems code looks like — and exactly how to spot when it falls short.
