Machine Learning Engineer
Machine Learning Engineer (AI Data Trainer)
About the Role
What if your deep technical expertise could directly shape how the world's most advanced AI models reason, plan, and solve problems? We're looking for Machine Learning Engineers to help train cutting-edge AI by producing high-quality reasoning data — the kind that teaches models to think like true experts.
This is a fully remote, flexible contract role built for experienced ML and engineering professionals who want to work on something that genuinely matters. You won't just be using AI — you'll be shaping how it thinks.

What You'll Do
- Produce precise, well-structured reasoning logs that walk through complex technical problems step by step
- Document sequential decision-making and strategic tool use in ways that AI models can learn from
- Generate high-quality training datasets that demonstrate expert-level problem-solving in real environments
- Review and refine AI-generated reasoning chains, catching gaps, errors, and logical inconsistencies
- Translate sophisticated ML concepts and workflows into clear, structured, reproducible documentation
- Work independently and asynchronously — fully on your own schedule
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
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Who You Are
