Backend Rust Engineer

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. • Organization: Alignerr • Type: Hourly Contract • Location: Remote • Commitment: 10–40 hours/week What You'll Do • Review AI-generated Rust code for correctness, memory safety, and idiomatic ownership patterns • Design challenging systems-level problems to probe the limits of AI's understanding of low-level constraints • Evaluate concurrent programming logic and identify potential race conditions or unsafe patterns in AI outputs • Assess performance optimization strategies and flag where AI reasoning breaks down • Ensure scientific rigor and type-safety across all evaluated deliverables • Provide clear, structured feedback that helps improve AI model behavior at the systems level • Work independently and asynchronously — on your own schedule Who You Are • 5+ years of professional experience writing production Rust with a strong focus on memory safety and concurrency • Deep familiarity with Rust's ownership model, lifetime system, and type guarantees • Strong background in systems programming and performance optimization • Able to clearly articulate complex low-level programming concepts in writing • Bachelor's degree or higher in Computer Science or a related technical field • Detail-oriented and methodical — you spot what others miss Nice to Have • Experience with distributed systems, operating systems, or developer tooling • Familiarity with unsafe Rust and the tradeoffs involved • Background in compiler design, embedded systems, or high-performance computing • Prior exposure to AI code evaluation or technical content review Why Join Us • Work on cutting-edge AI projects alongside leading research labs and AI teams • Fully remote and flexible — work when and where it suits you • Freelance autonomy with the structure of meaningful, technically rigorous work • Make a direct, tangible impact on how AI understands and generates systems-level code • Potential for ongoing work and contract extension as new projects launch • Training and onboarding support provided — hit the ground running
