Machine Learning Engineer

Machine Learning Engineer (AI Data Trainer)About The RoleWhat if your machine learning expertise could directly influence how the world's most advanced AI systems reason, plan, and solve problems? We're looking for Machine Learning Engineers to help train cutting-edge AI models by demonstrating expert-level reasoning — the kind that makes AI not just smart, but reliably, systematically intelligent.This is a fully remote, flexible contract role built for technical specialists who think clearly, work precisely, and want their expertise to leave a lasting mark on AI development.Organization: AlignerrType: Hourly ContractLocation: RemoteCommitment: 10–40 hours/weekWhat You'll DoConstruct precise, well-structured reasoning logs that walk through complex technical problems step by stepDocument sequential decision-making workflows — showing how an expert strategizes, selects tools, and arrives at solutionsGenerate high-quality training datasets that demonstrate proficient tool use and systematic problem-solving for AI modelsAudit and refine AI-generated reasoning steps, catching logical gaps and improving overall coherenceWork independently and asynchronously — fully on your own scheduleWho You AreProfessional background in Machine Learning, Software Engineering, or a related technical disciplineExceptional ability to articulate complex reasoning processes in a clear, structured, and reproducible wayStrong critical thinking skills — you can spot flawed logic and know how to fix itMethodical, detail-oriented, and consistent in your approach to technical problem-solvingComfortable working independently without hand-holdingMaster's Degree or PhD in a relevant fieldNice to HavePrior experience with data annotation, data labeling, or AI evaluation workflowsFamiliarity with LLM behavior, prompt engineering, or AI training pipelinesBackground in applied ML, NLP, or AI researchExperience writing technical documentation or reasoning tracesWhy Join UsCollaborate directly with leading AI research labs on genuinely cutting-edge projectsFully remote and flexible — work when and where it suits youFreelance autonomy with the substance of meaningful, high-impact technical workGain rare, hands-on exposure to how frontier LLMs are trained and evaluatedPotential for ongoing work and contract extension as new projects launch
