What if your technical expertise could directly shape 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 how expert minds think through complex technical challenges — step by step.
This isn't prompt engineering or basic annotation. You'll be creating the gold-standard reasoning traces that teach AI models how to strategize, use tools effectively, and reach reliable conclusions in real-world environments. Your work will have a direct, measurable impact on the next generation of AI.
This is a fully remote, flexible contract role designed for senior technical professionals who can commit anywhere from 10 to 40 hours per week.
Construct precise, structured reasoning logs that walk through sophisticated technical problems from start to finish
Document sequential decision-making and strategic planning workflows that reflect genuine expert thinking
Demonstrate proficient tool selection and use across complex, multi-step technical scenarios
Generate high-quality training datasets that show AI models what reliable, rigorous problem-solving looks like
Review and critically evaluate AI-generated reasoning steps — identifying gaps, errors, and opportunities for improvement
Work independently and asynchronously on task-based assignments at your own pace
Who You Are
Experienced qualified with a strong background in Machine Learning, Software Engineering, or a related technical discipline
Exceptional at breaking down complex logical processes and articulating them clearly in writing
A structured, methodical thinker who naturally documents their reasoning — not just their conclusions
Sharp critical eye — you can audit AI-generated reasoning and spot where it goes wrong
Self-directed and
