Senior Machine Learning Expert (AI Training)

What if your deep expertise in machine learning could directly shape how the world's most advanced AI systems think, plan, and solve problems

We're looking for Senior Machine Learning Experts to author high-fidelity reasoning traces — the structured, step-by-step records of how an intelligent system should approach and solve complex real-world tasks. This data becomes the backbone of training for frontier LLMs, directly influencing how reliably they reason, use tools, and make decisions at scale.

This is a fully remote, flexible contract role built for senior ML practitioners who want meaningful, intellectually stimulating work at the cutting edge of AI development.

Type: Hourly Contract

Location: Remote

Commitment: 10–40 hours/week

Author complex, high-fidelity reasoning traces that capture how an LLM should plan, reason, and act across sophisticated technical tasks

Design data strategies that enable LLMs to navigate intricate, multi-step real-world decision-making scenarios

Review and mentor structured traces to ensure optimal documentation of planning, tool use, and logical progression





Identify gaps and failure modes in AI reasoning and contribute structured solutions through annotated examples

Seasoned ML practitioner with significant experience in machine learning, deep learning, or related technical fields

Experienced with advanced LLM evaluation, training methodologies, or model reasoning workflows

Self-directed and comfortable working independently in an asynchronous remote workplace

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

Top-tier Kaggle competition results (Grandmaster or Master level), demonstrating deep expertise in model performance and feature engineering

Background in AI safety, alignment research, or RLHF workflows

Work on frontier AI projects in direct collaboration with leading research labs

Fully remote and async — work on your own schedule, from anywhere in the world

Freelance autonomy with intellectually stimulating, high-impact work

Potential for ongoing work and contract extension as new projects launch
