Summary
What you’ll impact
The Senior Machine Learning Engineer will author high-fidelity reasoning traces to teach large language models how to plan, use tools, and make decisions. This fully remote, contract position involves designing structured traces, ensuring architectural quality, and developing data strategies while working independently.
Responsibilities
What you'll do
- Author complex, high-fidelity reasoning traces that capture how an LLM plans, uses tools, and makes decisions to solve sophisticated technical tasks
- Design and document structured traces that reflect expert-level problem decomposition — showing every step from initial analysis to final output
- Apply senior architectural insight to ensure reasoning traces reflect best-in-class model decision-making patterns
- Review and refine trace quality to maintain rigorous standards for planning and tool-use documentation
- Develop data strategies that help LLMs navigate intricate real-world scenarios more reliably
- Work independently and asynchronously — fully on your own schedule
Requirements
What you’ll bring
- Significant hands-on experience in machine learning, AI research, or a closely related technical field
- Deep understanding of how LLMs reason, plan, and handle multi-step tasks
- Proven ability to decompose complex problems into clear, logical, well-documented steps
- Strong familiarity with advanced LLM evaluation and training methodologies
- Precise, structured written communicator — you can explain technical reasoning with clarity
- Self-directed and consistent when working independently without supervision
