Machine Learning Engineer

Machine Learning Engineer (AI Data Trainer) About the Role What 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 : Alignerr Type : Hourly Contract Location : Remote Commitment : 10-40 hours/week What You'll Do Construct precise, well-structured reasoning logs that walk through complex technical problems step by step Document sequential decision-making workflows - showing how an expert strategizes, selects tools, and arrives at solutions Generate high-quality training datasets that demonstrate proficient tool use and systematic problem-solving for AI models Audit and refine AI-generated reasoning steps, catching logical gaps and improving overall coherence Work independently and asynchronously - fully on your own schedule Who You Are Professional background in Machine Learning, Software Engineering, or a related technical discipline Exceptional ability to articulate complex reasoning processes in a clear, structured, and reproducible way Strong critical thinking skills - you can spot flawed logic and know how to fix it Methodical, detail-oriented, and consistent in your approach to technical problem-solving Comfortable working independently without hand-holding Master's Degree or PhD in a relevant field Nice to Have Prior experience with data annotation, data labeling, or AI evaluation workflows Familiarity with LLM behavior, prompt engineering, or AI training pipelines Background in applied ML, NLP, or AI research Experience writing technical documentation or reasoning traces Why Join Us Collaborate directly with leading AI research labs on genuinely cutting-edge projects Fully remote and flexible - work when and where it suits you Freelance autonomy with the substance 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 Alignerr
