Backend Rust Engineer

Backend Rust Engineer (AI Training) About The Role What if your deep expertise in Rust could directly shape how the next generation of AI understands systems-level programming?

We're looking for experienced Rust engineers to review, evaluate, and challenge AI-generated code — helping ensure that the models influencing software development worldwide can reason correctly about memory safety, ownership, concurrency, and performance.

This is a fully remote, flexible contract role designed for seasoned Rust developers who know what good systems code looks like — and exactly how to spot when it falls short.

Organization: AlignerrType: Hourly ContractLocation: RemoteCommitment: 10–40 hours/week What You'll Do Review AI-generated Rust code for correctness, memory safety, and idiomatic ownership patternsDesign challenging systems-level problems to probe the limits of AI's understanding of low-level constraintsEvaluate concurrent programming logic and identify potential race conditions or unsafe patterns in AI outputsAssess performance optimization strategies and flag where AI reasoning breaks downEnsure scientific rigor and type-safety across all evaluated deliverablesProvide clear, structured feedback that helps improve AI model behavior at the systems levelWork independently and asynchronously — on your own schedule Who You Are 5+ years of professional experience writing production Rust with a strong focus on memory safety and concurrencyDeep familiarity with Rust's ownership model, lifetime system, and type guaranteesStrong background in systems programming and performance optimizationAble to clearly articulate complex low-level programming concepts in writingBachelor's degree or higher in Computer Science or a related technical fieldDetail-oriented and methodical — you spot what others miss Nice to Have Experience with distributed systems, operating systems, or developer toolingFamiliarity with unsafe Rust and the tradeoffs involvedBackground in compiler design, embedded systems, or high-performance computingPrior exposure to AI code evaluation or technical content review Why Join Us Work on cutting-edge AI projects alongside leading research labs and AI teamsFully remote and flexible — work when and where it suits youFreelance autonomy with the structure of meaningful, technically rigorous workMake a direct, tangible impact on how AI understands and generates systems-level codePotential for ongoing work and contract extension as new projects launchTraining and onboarding support provided — hit the ground running
