Senior Rust Engineer — AI Data & Infrastructure

Senior Rust Engineer — AI Data & Infrastructure

About the Role

What if your systems programming expertise could directly shape the infrastructure powering next-generation AI? We're looking for a Senior Rust Engineer to build and optimize the high-performance data pipelines, annotation tooling, and evaluation systems that sit at the heart of cutting-edge AI development.

This is a fully remote contract role working alongside leading AI labs on real production systems — not toy projects. If you care deeply about performance, correctness, and building things that scale, this is the work you've been waiting for.

• Organization: Alignerr
• Type: Hourly Contract
• Location: Remote
• Commitment: 20–40 hours/week

What You'll Do

• Design, build, and optimize high-performance systems in Rust supporting AI data pipelines and evaluation workflows
• Develop backend services and tooling for large-scale data annotation, validation, and quality control
• Improve reliability, performance, and memory safety across existing Rust codebases
• Collaborate with data, research, and engineering teams to support model training and evaluation workflows
• Identify bottlenecks and edge cases in data and system behavior, and implement scalable, production-ready fixes
• Participate in synchronous design reviews to iterate on system architecture and implementation decisions

Who You Are

• 5+ years of professional experience writing production-grade Rust
• Strong systems programming background — you think deeply about performance, concurrency, and memory safety
• Proven experience building backend services, developer tooling, or data pipelines
• Clear and effective communicator in both written and verbal contexts
• Able to commit 20–40 hours per week with reliability and consistency

Nice to Have

• Prior experience with data annotation, data quality systems, or evaluation pipelines
• Familiarity with AI/ML workflows, model training, or benchmarking infrastructure
• Experience with distributed systems or large-scale developer tooling
• Background working with or alongside AI research teams

Why Join Us

• Work on cutting-edge AI infrastructure alongside leading research labs
• Fully remote and flexible — work from wherever you do your best work
• Freelance autonomy with the structure of meaningful, high-impact engineering work
• Make a direct, tangible contribution to AI systems that operate at real scale
• Potential for ongoing work and contract extension as new projects launch
