About the Role
What if your Rust expertise could directly shape the infrastructure powering the next generation of AI? We're looking for a senior Rust engineer to build and optimize the distributed systems, data pipelines, and tooling that leading AI labs depend on — working on real production systems with real consequences.
This is a fully remote, flexible contract role. If you're the kind of engineer who gets satisfaction from writing safe, performant, correct code at scale — and you want that work to matter — 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 AI data pipelines and evaluation workflows
- Develop full-stack tooling and backend services for large-scale data annotation, validation, and quality control
- Improve reliability, performance, and 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 distributed system behavior and implement scalable solutions
- 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
- 3–5+ years of professional experience writing production-grade Rust
- Strong background in building distributed services using RPC frameworks, distributed state management, or consensus protocols
- Experienced debugging complex concurrency issues — deadlocks, race conditions — using async instrumentation and tracing tools
- Able to commit 20–40 hours per week on a consistent basis
- Self-directed and reliable when working in a remote, async-first environment
Nice to Have
- Prior experience with data annotation, data quality pipelines, or evaluation systems
- Familiarity with AI/ML workflows, model training, or benchmarking infrastructure
- Experience building distributed systems or developer tooling at scale
Why Join Us
- Work on cutting-edge AI infrastructure projects alongside leading research labs
- Fully remote and flexible — work when and where you do your best work
- Freelance autonomy with the substance of high-impact, production-grade engineering
- Contribute directly to systems that shape how next-generation AI models are built and evaluated
- Potential for ongoing work and contract extension as new projects launch
