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
