AlignerrCoding & software eval
Machine Learning Engineer
up to $70/hr
About this role, in Alignerr's words
What if your deep technical expertise could directly shape how the world's most advanced AI models reason, plan, and solve problems? We're looking for Machine Learning Engineers to help train cutting-edge AI by producing high-quality reasoning data — the kind that teaches models to think like true experts.
What you'll do
- Produce precise, well-structured reasoning logs that walk through complex technical problems step by step
- Document sequential decision-making and strategic tool use in ways that AI models can learn from
- Generate high-quality training datasets that demonstrate expert-level problem-solving in real environments

- Review and refine AI-generated reasoning chains, catching gaps, errors, and logical inconsistencies
- Translate sophisticated ML concepts and workflows into clear, structured, reproducible documentation
- Work independently and asynchronously — fully on your own schedule
Candidate background
Who You Are
- Professional background in Machine Learning, Software Engineering, or a related technical discipline
- Able to explain complex reasoning processes with precision and clarity — not just what you did, but why
- Strong critical thinker who can audit multi-step reasoning and identify where logic breaks down
- Detail-oriented and methodical — you take quality seriously and it shows in your work
- Comfortable working independently on technically demanding tasks without hand-holding
- Master's Degree or PhD in a relevant technical field
