Data Infrastructure Engineer (Rust) - High Performance Computing

About the Role

What if your mastery of Rust could directly shape the infrastructure powering the next generation of AI? We're looking for a Senior Rust Engineer to build the high-performance data pipelines, annotation tooling, and evaluation systems that leading AI labs depend on to train and improve their most advanced models.

This is a fully remote, flexible contract role for an elite systems engineer who knows Rust at a deep level - memory layout, SIMD, concurrency, and all. You'll work on real production systems at the frontier of AI development, collaborating with research and engineering teams doing genuinely important work.

    : Hourly Contract
  • Location
    : Remote
  • 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 full-stack tooling and backend services for data annotation, validation, and quality control
  • Identify and eliminate bottlenecks through deep profiling, SIMD optimizations, and careful memory management
  • Improve reliability, performance, and safety across existing Rust codebases
  • Collaborate with data, research, and engineering teams to support model training and evaluation workflows
  • Participate in synchronous design reviews and iterate quickly on system architecture decisions
Who You Are
  • 5+ years
    of professional experience writing production-grade Rust
  • Deep expertise in
    data parallelism and concurrency patterns
    - you know how to maximize CPU saturation
  • Strong command of
    memory layout, SIMD optimizations, and heap allocation strategies
    to hunt down and fix performance bottlenecks
  • Native or fluent English speaker with clear written and verbal communication skills
  • Able to commit 20-40 hours per week consistently
  • Self-directed and comfortable working asynchronously in a remote engineering environment
Nice to Have
  • Prior experience with data annotation pipelines, data quality systems, or evaluation infrastructure
  • Familiarity with AI/ML workflows, model training, or benchmarking pipelines
  • Experience with distributed systems architecture or developer tooling
  • Background working with or alongside AI research teams
Why Join Us
  • Work on cutting-edge AI infrastructure projects alongside leading research labs
  • Fully remote and flexible - structure your work around your life
  • Freelance autonomy with the substance of high-impact, senior-level engineering work
  • Tackle genuinely hard systems problems that matter at scale
  • Potential for ongoing work and contract extension as new projects launch
