Job description

Principal Rust Engineer - ML Infrastructure (AI Training)
About the Role
What if your deep Rust expertise could directly influence the infrastructure powering the world's most advanced AI models? We're looking for a Principal Rust Engineer to build and optimize the high-performance systems that leading AI labs depend on - from data pipelines and annotation tooling to evaluation infrastructure at production scale.
This is a fully remote, flexible contract role for engineers who live and breathe Rust and want to work on problems that genuinely matter.

  • Commitment
    : 20-40 hours/week
What You'll Do
  • Design, build, and optimize high-performance Rust systems supporting large-scale AI data pipelines and evaluation workflows
  • Develop backend services and full-stack tooling for data annotation, validation, and quality control
  • Improve reliability, performance, and memory safety across existing Rust codebases
  • Identify and resolve bottlenecks, edge cases, and failure modes in data-intensive systems
  • Collaborate closely with data, research, and engineering teams to support model training and evaluation workflows
  • Participate in synchronous design reviews to iterate on architecture and implementation decisions
Who You Are
  • Native or fluent English speaker with clear written and verbal communication skills
  • 5+ years of professional experience writing production Rust for data-intensive applications
  • Deep understanding of memory management and zero-copy deserialization with minimal runtime overhead
  • Experienced integrating Rust with machine learning frameworks or columnar data standards to support model training workflows
  • Able to commit 20-40 hours per week with consistency and reliability
  • Self-directed and effective working asynchronously across distributed teams
Nice to Have
  • Prior experience with data annotation, data quality pipelines, or evaluation systems
  • Familiarity with AI/ML workflows, model training, or benchmarking pipelines
  • Experience with distributed systems or developer tooling
  • Background contributing to or maintaining open-source Rust projects
Why Join Us
  • Work directly on infrastructure used by leading AI research labs on real production systems
  • Fully remote and flexible - work when and where you do your best work
  • Freelance autonomy with meaningful, high-impact technical work that pushes the boundaries of what Rust can do
  • Collaborate with world-class engineers and researchers working on next-generation AI
  • Potential for ongoing work and contract extension as new projects launch
