Senior Machine Learning Engineer (AI Training)

What if your deep expertise in machine learning could directly influence how the next generation of AI systems reason, plan, and solve problems We're looking for Senior Machine Learning Engineers to author high-fidelity reasoning traces — the structured, step-by-step thought processes that teach large language models how to think.

This is a fully remote, flexible contract role built for senior-level ML professionals who understand model behavior from the inside out. Your work won't just describe what AI does — it will shape how AI reasons.

Type: Hourly Contract

Location: Remote

Commitment: 10–40 hours/week

Author complex, high-fidelity reasoning traces that capture planning, tool use, and multi-step decision-making for sophisticated technical tasks

Review and quality-check traces produced by other contributors, ensuring clarity, logical soundness, and technical accuracy

Develop data strategies that help LLMs navigate ambiguous, multi-layered problems with reliable, consistent reasoning

Experienced in machine learning, AI research, or a closely related technical field — you understand how models learn and where they fail





Familiar with LLM training pipelines, evaluation methodologies, and the mechanics of how models develop reasoning capabilities

A accurate, structured thinker who can translate expertise into high-quality written documentation

Self-directed and reliable — you produce consistent, high-quality work without hand-holding

Prior experience with data annotation, data quality assurance, or AI evaluation systems

Top-tier Kaggle competition results (Grandmaster or Master level) demonstrating elite-level model understanding and performance optimization

Background in reinforcement learning, chain-of-thought prompting, or agentic AI systems

Experience working with or evaluating frontier LLMs

Work directly with some of the world's leading AI research teams and labs on cutting-edge model development

Fully remote and flexible — structure your work around your life, not the other way around

Freelance autonomy with meaningful, intellectually stimulating work on problems that actually matter

Potential for ongoing work and contract extension as new projects launch
