Machine Learning Engineer
About this role
About the Role What if your deep technical expertise 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 and improve large language models by demonstrating how expert-level thinking actually works — step by step, tool by tool, decision by decision. This is a fully remote, flexible contract role designed for experienced technical professionals who know how to break down complex problems and explain their reasoning with precision. - Organization: Alignerr - Type: Hourly Contract - Location: Remote - Commitment: 10–40 hours/week What You'll Do - Construct detailed, structured reasoning logs that walk through how sophisticated technical problems are approached and solved - Document sequential decision-making workflows — capturing how tools are selected, applied, and evaluated at each step - Generate high-quality training datasets that demonstrate proficient, expert-level problem-solving for AI models - Audit and refine AI-generated reasoning traces to ensure logical consistency and technical accuracy - Translate complex methodologies into clearly articulated, reproducible workflows Who You Are - Professionally experienced in Machine Learning, Software Engineering, or a related technical discipline - Exceptionally clear at explaining intricate technical processes — you can make complex reasoning legible - A rigorous critical thinker who can identify gaps, errors, or inefficiencies in AI-generated reasoning - Comfortable working independently and asynchronously on task-based assignments - Holds or is pursuing a Master's Degree or PhD in a relevant field Nice to Have - Prior experience with data annotation, data quality assurance, or AI evaluation systems - Familiarity with LLM behavior, prompt engineering, or model evaluation methodologies - Background in technical writing, research documentation, or structured problem-solving frameworks - Experience working across multiple ML domains — NLP, computer vision, reinforcement learning, etc. Why Join Us - Work directly with leading AI research labs on projects at the frontier of model development - Fully remote and async — work when and where it suits you, with no fixed hours - Freelance autonomy with meaningful, intellectually engaging work - Gain rare, hands-on insight into how cutting-edge LLMs are trained and improved - Potential for ongoing work and contract extension as new projects launch
