About the Role

What if your expertise in machine learning could directly shape how the next generation of AI systems reason, plan, and solve real-world problems? We're looking for Machine Learning Engineers to work at the frontier of AI development — capturing the step-by-step reasoning and decision-making processes that teach large language models to think more reliably.

This is a fully remote, flexible contract role built for technical minds who can break down complex logic and communicate it with precision. You won't just observe how AI is trained — you'll be a core part of making it smarter.

  • Organization: Alignerr
  • Type: Hourly Contract
  • Location: Remote
  • Commitment: 10–40 hours/week

What You'll Do

  • Author clear, structured reasoning traces that document how an AI should plan and execute complex technical tasks
  • Map out step-by-step decision-making processes — including tool use, logic branching, and problem-solving strategies
  • Create high-quality training data that demonstrates reliable, grounded reasoning in real-world scenarios
  • Evaluate and refine AI outputs to improve the quality and consistency of model decision-making
  • Work independently and asynchronously — fully on your own schedule

Who You Are

  • Background in Machine Learning, Computer Science, or a closely related technical field
  • Able to articulate complex logical and technical reasoning in clear, structured writing
  • Strong analytical thinker who can identify gaps or errors in AI decision-making workflows
  • Detail-oriented and consistent — you take pride in producing high-quality, precise work
  • Self-motivated and comfortable working independently without close supervision

Nice to Have

  • Prior experience with data annotation, data quality assurance, or AI evaluation systems
  • Familiarity with LLM architectures, prompt engineering, or RLHF workflows
  • Background in software engineering, applied research, or technical writing
  • Experience working with structured reasoning frameworks or chain-of-thought methodologies

Why Join Us

  • Work directly on cutting-edge AI projects alongside leading research labs and AI teams
  • Fully remote and flexible — work when and where it suits you
  • Freelance autonomy with the structure of meaningful, impactful technical work
  • Get rare, hands-on exposure to how advanced LLMs are actually trained and improved
  • Contribute to AI development that shapes how models reason across millions of real-world use cases
  • Potential for ongoing work and contract extension as new projects launch
