Senior Machine Learning Expert (AI Training)
About the Role
What if your deep expertise in machine learning could directly influence how the next generation of AI systems reason, plan, and make decisions?
We’re looking for Senior Machine Learning Experts to help build the foundational training data that teaches large language models how to think — step by step, in real-world scenarios.
This is a fully remote, flexible contract role designed for experienced ML professionals who understand model architecture, reasoning pipelines, and what separates good AI outputs from great ones.
- Organization: Alignerr
- Type: Hourly Contract
- Location: Remote
- Commitment: 10–40 hours/week
What You’ll Do
- Author complex, high-fidelity reasoning traces that capture how an LLM should plan, use tools, and make decisions to solve real technical tasks
- Design structured, step-by-step decision-making data that trains AI models to reason more reliably in production environments
- Review and refine reasoning traces contributed by others, ensuring:
- Logical coherence
- Planning quality
- Tool-use accuracy
- Develop data strategies for navigating intricate, multi-step problem scenarios that push model capabilities forward
- Apply senior-level architectural insight to validate that traces reflect sound, expert-level machine learning thinking
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
