About The Role
What if your Rust expertise could directly shape the infrastructure powering the next generation of AI models? We're looking for a senior Rust engineer to build and optimize the high-performance systems that leading AI labs depend on — from data pipelines and annotation tooling to evaluation frameworks and backend services.
This is a fully remote contract role with meaningful, high-impact work across real production systems. If you write Rust the way it's meant to be written — fast, safe, and reliable — this is the role for you.
Organization: Alignerr
Type: 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 backend services and full-stack tooling for data annotation, validation, and quality control
Improve reliability, safety, and performance across existing Rust codebases
Collaborate with data, research, and engineering teams to support model training and evaluation infrastructure
Identify bottlenecks and edge cases across data flows and system behavior — then implement scalable, production-grade fixes
Participate in synchronous design reviews to iterate on architecture and implementation decisions
Who You Are
5+ years of professional experience writing production Rust
Proven track record building high-performance backend web services and robust CLI tooling
Experienced with type-safe database interactions and connection pooling at scale
Clear, confident written and verbal communicator in English
Able to commit 20–40 hours per week consistently
Self-directed and effective working asynchronously across a distributed team
Nice to Have
Prior experience with data annotation, data quality pipelines, or model evaluation systems
Familiarity with AI/ML workflows, model training, or benchmarking infrastructure
Experience with distributed systems or developer tooling
Background working directly with AI or research engineering teams
Why Join Us
Work on real, high-impact AI infrastructure alongside top research labs
Fully remote and flexible — build from wherever you do your best work
Freelance autonomy with the structure of meaningful, long-term technical projects
Solve genuinely hard systems problems that directly influence how next-generation AI is built and evaluated
Potential for ongoing work and contract extension as new projects launch
