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
