Senior Machine Learning Expert (AI Training)
About the Role
What if your deep expertise in machine learning could directly determine how the next generation of AI systems reason, plan, and make decisions?
We're looking for Senior Machine Learning Experts to author high-fidelity reasoning traces — the structured, step-by-step thinking records that teach large language models how to tackle complex, real-world problems with precision and reliability.
This is a fully remote, flexible contract role built for senior-level ML professionals who understand not just how models work, but how they should think.
Organization: Alignerr Type: Hourly Contract Location: Remote Commitment: 10–40 hours/week
What You'll Do
- Author complex, high-fidelity reasoning traces that capture:
- Planning
- Tool use
- Step-by-step decision-making for sophisticated technical tasks
- Design and document structured traces demonstrating how an LLM should navigate intricate, multi-step, real-world scenarios
- Review and mentor reasoning trace quality, ensuring:
- Logical clarity
- Architectural soundness
- Reliable model decision pathways
- Develop data strategies to expose LLMs to:
- Nuanced edge cases
- Advanced problem-solving patterns
- Apply your senior-level ML intuition to push the boundaries of how AI models reason and act
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
