Systems Programmer - AI Data Pipelines

Systems Programmer — AI Data PipelinesAbout The RoleWhat if your Rust expertise could directly shape the infrastructure behind the world's most advanced AI systems? We're looking for a senior Rust engineer to design and build the high-performance data pipelines, annotation tooling, and evaluation systems that leading AI labs depend on to train and improve their models.This is a fully remote contract role working on real production systems — not toy projects. You'll collaborate with research and engineering teams at the frontier of AI development, solving hard systems problems that matter.Organization: AlignerrType: Hourly ContractLocation: RemoteCommitment: 20–40 hours/weekWhat You'll DoDesign, build, and optimize high-performance Rust systems supporting AI data pipelines and evaluation workflowsDevelop full-stack tooling and backend services for large-scale data annotation, validation, and quality controlImprove reliability, performance, and safety across existing production Rust codebasesIdentify bottlenecks and edge cases in data and system behavior — then implement scalable, robust fixesCollaborate with data, research, and engineering teams to support model training and evaluation workflowsParticipate in synchronous design and code reviews to iterate on architecture and implementation decisionsWho You AreNative or fluent English speaker with strong written and verbal communication skills3–5+ years of professional experience writing production RustDeep command of Rust lifetimes, ownership mechanics, and idiomatic error handling patternsProven experience building I/O-bound data pipelines with robust retry and backoff logicAble to commit 20–40 hours per week with reliable availability for collaborationSelf-directed and effective working independently in a remote environmentNice to HavePrior experience with data annotation, data quality, or evaluation systemsFamiliarity with AI/ML workflows, model training, or benchmarking pipelinesExperience with distributed systems or developer toolingBackground in systems programming, infrastructure engineering, or platform workWhy Join UsWork directly with leading AI labs on production systems at the frontier of AI researchFully remote and flexible — structure your week around the work, not the other way aroundFreelance autonomy paired with meaningful, high-impact engineering challengesBuild systems that have a direct, measurable influence on how next-generation AI models are trained and evaluatedPotential for ongoing work and contract extension as new projects launch
