Backend Rust Engineer
About this role
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
