About the role
About The Role What if your systems engineering expertise could directly shape how the world's most advanced AI models are built, trained, and evaluated? We're looking for Senior Systems Engineers to work alongside leading AI labs — designing and building the high-performance pipelines, annotation tooling, and evaluation infrastructure that make next-generation AI possible. This is a fully remote contract role for engineers who move fast, think deeply about systems, and want their work to matter. If you write production-grade Go, Rust, Python, or C++ and care about correctness, performance, and scale — this is built for you. Organization: AlignerrType: Hourly ContractLocation: RemoteCommitment: 20–40 hours/week What You'll Do Design, build, and optimize high-performance backend systems using Go, Rust, Python, or C++Develop tooling and services powering large-scale data annotation, validation, and evaluation workflowsBuild and maintain reliable data pipelines that support AI model training and benchmarkingImprove performance, scalability, and correctness across production codebasesCollaborate with data, research, and engineering teams on model-facing infrastructureIdentify bottlenecks, edge cases, and failure modes across systems and data flowsParticipate in architecture and implementation reviews to continuously raise the bar Who You Are 5+ years of professional experience in Go, Rust, Python, or C++Strong systems or backend engineering background with production experienceProven track record building reliable services, internal tooling, or data pipelinesSharp instincts for performance, reliability, and correctness at scaleClear communicator — both in writing and in technical discussionsAble to commit 20–40 hours per week consistently Nice to Have Experience with data annotation, data quality systems, or evaluation pipelinesFamiliarity with AI/ML workflows, model training, or benchmarking infrastructureBackground in distributed systems or high-throughput data processingExperience building developer tooling or internal platform infrastructure Why Join Us Work on real, high-impact infrastructure alongside leading AI research labsFully remote — work from wherever you do your best workFlexible contract engagement with meaningful, senior-level technical problemsContribute to systems that directly influence how the next generation of AI is built and evaluatedPotential for ongoing work and contract extension as projects scale
