Backend Rust Developer
About this role
About the Role What if your deep knowledge of Rust — memory safety, ownership semantics, concurrency — could directly shape how AI understands and generates systems-level code for developers worldwide? We're looking for experienced Rust engineers to evaluate AI-generated code, stress-test its correctness, and help train the next generation of AI models to think like expert systems programmers. This is a fully remote, flexible contract role built for senior engineers who want to do meaningful work on their own schedule. - Organization: Alignerr - Type: Hourly Contract - Location: Remote - Commitment: 10–40 hours/week What You'll Do - Review AI-generated Rust code for memory safety, ownership correctness, and idiomatic patterns - Design challenging systems-level problems to probe the model's understanding of low-level constraints - Evaluate concurrent programming logic and identify potential race conditions or undefined behavior in AI outputs - Assess performance optimization strategies and flag inefficiencies in AI-generated solutions - Ensure type-safety and scientific rigor across all code evaluation tasks - Provide structured, expert-level feedback that directly improves how AI models reason about Rust and systems programming Who You Are - 5+ years of professional experience writing production-grade Rust - Deep understanding of memory safety, ownership, borrowing, and lifetime semantics - Strong background in systems programming — you think in terms of performance, safety, and correctness - Experienced with concurrency patterns and comfortable spotting subtle race conditions - Able to clearly articulate complex low-level concepts in written English - Bachelor's degree or higher in Computer Science or a related technical field Nice to Have - Experience with distributed systems, embedded systems, or developer tooling - Familiarity with unsafe Rust and the constraints around its correct use - Background in compiler internals, OS development, or performance profiling - 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 — take on as many or as few hours as suits your schedule - Freelance autonomy with the structure of meaningful, task-based work - Make a direct, expert-level impact on how AI understands one of the most demanding programming languages in the world - Potential for ongoing work and contract extension as new projects launch
