Backend Rust Engineer

Backend Rust Engineer (AI Training) 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
