AlignerrCoding & software eval
Backend Rust Engineer
up to $90/hr
About this role, in Alignerr's words
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?
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
Show all 6 itemsHide the other 3 in What you'll do
- 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
Candidate background
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

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.
