Backend Rust Engineer
About this role
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
