Backend Rust Engineer

Backend Rust Engineer

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
