Senior Machine Learning Engineer (AI Training)

About The Role

What if your deep knowledge of 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 Engineers to help train cutting-edge large language models — not by writing traditional code, but by crafting the structured reasoning traces that teach AI how to think step by step. Your architectural intuition and understanding of model behaviour will have a direct, lasting impact on how next-generation AI approaches real-world challenges.

This is a fully remote, flexible contract role built for experienced ML professionals who want to work at the frontier of AI development — on their own schedule.

• Organization: Alignerr
• Type: Hourly Contract
• Location: Remote
• Commitment: 10–40 hours/week

What You'll Do

• Author complex, high-fidelity reasoning traces that document how an LLM should plan, use tools, and make decisions across sophisticated technical tasks




• Design structured traces that capture multi-step problem decomposition, logical inference, and real-world decision-making strategies
• Review and refine reasoning traces to ensure they reflect sound ML thinking and produce reliable, generalizable model behaviour
• Develop data strategies that help LLMs navigate intricate, open-ended scenarios with greater consistency and accuracy
• Contribute senior-level insights that elevate the overall quality and depth of training data

Who You Are

• Experienced in machine learning, AI research, or a closely related technical field — you understand how models learn and where they go wrong
• Skilled at breaking down complex problems into clear, logical, documented steps — the kind of thinking that makes excellent training data
• Familiar with LLM evaluation, fine-tuning, or training methodologies
• A precise, structured communicator who can make sophisticated reasoning legible and reproducible
• Self-directed and comfortab
