Machine Learning Engineer (AI Data Trainer)About The RoleWhat if your technical expertise could directly influence how the world's most advanced AI systems learn to reason, plan, and solve problems? We're looking for Machine Learning Engineers to help train cutting‐edge large language models — not by writing model code, but by demonstrating how expert technical minds actually think. This is a fully remote, flexible contract role built for experienced engineers and researchers who can articulate complex reasoning with precision. Your work will form the backbone of training data that teaches AI to think like a specialist. Organization: Alignerr Type: Hourly Contract Location: Remote Commitment: 10–40 hours/week What You'll DoProduce precise, well‐structured reasoning logs that capture how expert engineers approach sophisticated technical problems Document step‐by‐step decision‐making workflows — covering strategy, tool selection, and problem decomposition Generate high‐quality training datasets that demonstrate proficient, reliable problem‐solving for AI models Audit and refine AI‐generated reasoning chains, identifying gaps, errors, or logical inconsistencies Work across a range of complex ML and engineering scenarios, translating expert intuition into structured, learnable examples Who You AreProfessional background in Machine Learning, Software Engineering, or a related technical discipline Exceptional ability to explain complex technical reasoning in a clear, organized, and reproducible way Strong critical thinking skills — you can evaluate the quality of a logical argument and know when something doesn't hold up Methodical and detail‐oriented, with a consistent approach to structured problem‐solving Comfortable working independently and managing your own time across flexible hours Nice to HaveMaster's Degree or PhD in Machine Learning, Computer Science, or a related field Prior experience with data annotation, evaluation systems, or AI quality assurance Familiarity with LLM behavior, prompt engineering, or AI reasoning frameworks Background in technical writing, research documentation, or instructional design Why Join UsWork directly with teams building some of the most advanced AI models in the world Fully remote and asynchronous — work on your own schedule, from anywhere Freelance autonomy with the structure of meaningful, high‐impact technical work Gain rare, hands‐on exposure to how frontier LLMs are trained and evaluated Potential for ongoing work and contract extension as new projects launch#J-18808-Ljbffr
