About the Role

What if your deep expertise in Rust — memory safety, ownership models, zero-cost abstractions — could directly shape how AI understands and generates systems-level code for developers worldwide?

We're looking for experienced Rust engineers to review, evaluate, and challenge AI-generated code at the systems level. You'll be on the front lines of AI development, applying your hard-won expertise to help AI models reason better about one of the most demanding programming languages in use today.

This is a fully remote, flexible contract role designed to fit around your existing commitments — whether you're a full-time engineer looking for meaningful side work or a seasoned contractor seeking your next high-impact engagement.

  • 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 understanding in low-level programming
  • Evaluate concurrent programming logic and identify potential race conditions, deadlocks, or unsafe patterns in AI-produced code
  • Assess performance optimization decisions and validate that AI responses reflect sound systems engineering judgment
  • Ensure type-safety, scientific rigor, and production-quality standards across all evaluation tasks
  • Provide clear, structured feedback that helps improve how AI models reason about Rust and systems programming

Who You Are

  • 5+ years of professional experience writing production Rust with a strong focus on memory safety and concurrency
  • Deep understanding of Rust's ownership model, lifetimes, traits, and async patterns
  • Strong background in systems programming — you think in terms of performance, resource constraints, and low-level behavior
  • Able to articulate complex technical concepts clearly in written English
  • Naturally rigorous — you catch edge cases others miss and hold code to a high standard
  • Bachelor's degree or higher in Computer Science or a related technical field

Nice to Have

  • Experience with distributed systems architecture or developer tooling
  • Familiarity with unsafe Rust, FFI, or embedded/systems targets
  • Background in performance profiling, benchmarking, or compiler internals
  • Prior experience with AI evaluation, code review tooling, or technical writing

Why Join Us

  • Work on cutting-edge AI projects alongside leading AI research labs
  • Fully remote and flexible — work when and where it suits you
  • Freelance autonomy with the structure of meaningful, well-scoped technical work
  • Make a direct, measurable impact on how AI models understand and generate Rust code
  • Potential for ongoing work and contract extension as new projects launch
