Machine Learning Engineer

Machine Learning Engineer (AI Data Trainer)About The RoleWhat if your expertise in machine learning could directly shape how the next generation of AI models reason, plan, and solve real-world problems? We're looking for Machine Learning Engineers to help train cutting-edge AI by demonstrating how expert technical minds actually think — step by step, tool by tool, decision by decision.This is a fully remote, flexible contract role built for experienced ML and engineering professionals who want to put their deep technical knowledge to work at the frontier of AI development.Organization: AlignerrType: Hourly ContractLocation: RemoteCommitment: 10–40 hours/weekWhat You'll DoConstruct precise, well-structured reasoning logs that walk through sophisticated technical problems from start to finishDocument sequential decision-making workflows — how you strategize, select tools, and adapt your approachGenerate high-quality training data that shows AI models what expert-level problem-solving actually looks likeAudit and refine AI-generated reasoning chains to identify gaps, errors, or logical inconsistenciesDemonstrate proficient tool use across complex ML and engineering scenariosWork independently and asynchronously — fully on your own scheduleWho You AreProfessional background in Machine Learning, Software Engineering, or a closely related technical disciplineExceptional ability to articulate complex reasoning and methodologies in a clear, structured wayStrong critical thinking skills — you can evaluate a line of logic and spot exactly where it goes wrongComfortable working independently on intellectually demanding, task-based assignmentsMaster's Degree or PhD in a relevant technical fieldNice to HavePrior experience with data annotation, data quality assurance, or AI evaluation workflowsFamiliarity with large language models (LLMs) and how they're trained or fine-tunedBackground in technical writing, documentation, or instructional designExperience working across multiple ML frameworks or toolchainsWhy Join UsWork directly with leading AI research labs on genuinely cutting-edge projectsFully remote and flexible — work when and where it suits youFreelance autonomy with the structure of meaningful, high-impact technical workRare inside access to how frontier LLMs are built and trainedPotential for ongoing work and contract extension as new projects launch
