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
