Rust Software Engineer — Distributed Systems (AI Infrastructure)
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
