Rust Jobs for Rustaceans

About the Role
What if your deep expertise in Rust could directly shape how AI writes and reasons about systems-level code? We're looking for experienced Rust engineers to review, evaluate, and improve AI-generated Rust code — helping ensure the next generation of AI understands memory safety, concurrency, and performance at an expert level.

This is a fully remote, flexible contract role built for senior Rust developers who want meaningful, intellectually engaging work on their own schedule.

• Organization: Alignerr
• Type: Hourly Contract
• Location: Remote
• Commitment: 10–40 hours/week

Key Responsibilities:

• Design, build, and optimize production-grade Rust systems supporting large-scale AI data pipelines and model evaluation workflows
• Develop full-stack backend services and tooling for data annotation, validation, and quality control
• Improve reliability, performance, and safety across existing Rust codebases
• Debug complex concurrency issues — deadlocks, race conditions, and async edge cases — using instrumentation and tracing tools
• Collaborate with data, research, and engineering teams to support model training and evaluation infrastructure
• Identify bottlenecks and implement scalable, robust fixes
• Participate in synchronous design reviews to iterate on system architecture and implementation decisions

Requirements:

• 3–5+ years of professional experience writing production Rust
• Strong background in distributed systems — RPC frameworks, distributed state, consensus mechanisms
• Experienced at debugging complex concurrency issues using async instrumentation and tracing tools
• Native or fluent English speaker with clear written and verbal communication skills
• Able to commit 20–40 hours per week with reliable availability
• Self-directed and comfortable working asynchronously in a remote environment

Nice to Have

• Prior experience with data annotation, data quality, or evaluation systems
• Familiarity with AI/ML workflows, model training pipelines, or benchmarking infrastructure
• Background in developer tooling or systems-level software
• Experience contributing to or maintaining open-source Rust projects

Why Join Us

• Work on cutting-edge AI projects alongside leading research labs and AI teams
• Fully remote and flexible — work when and where it suits you
• Freelance autonomy with the structure of meaningful, technically rigorous work
• Make a direct, tangible impact on how AI understands and generates systems-level code
• Potential for ongoing work and contract extension as new projects launch
• Training and onboarding support provided — hit the ground running
