Senior Machine Learning Expert (AI Training)

About The Role

What if your deep expertise in machine learning could directly shape how the next generation of AI systems reasons, plans, and makes decisions? We're looking for Senior Machine Learning Experts to author high-fidelity reasoning traces — the structured, step-by-step records of how an AI should think through complex technical problems.

This is frontier work. The data you create trains LLMs to reason more reliably in real-world scenarios, influencing how millions of people interact with AI. If you're a senior-level ML practitioner who loves breaking down hard problems and documenting rigorous thought processes, this role was built for you.

This is a fully remote, flexible contract role. You set your own schedule — 10 to 40 hours per week, on your terms.

• 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, and step-by-step decision-making for sophisticated ML tasks




• Design and document data strategies that help LLMs navigate intricate, real-world problem-solving scenarios
• Review and mentor structured traces to ensure optimal logical flow, clarity, and technical accuracy
• Apply senior-level architectural insights to validate and improve how AI models reason through multi-step challenges
• Work independently and asynchronously — entirely on your own schedule

Who You Are

• Experienced machine learning practitioner with significant hands-on expertise in ML, deep learning, or related technical fields
• Skilled at decomposing complex, ambiguous problems into explicit, logical, and well-documented steps
• Familiar with LLM evaluation, training methodologies, and how large models reason and fail
• Detail-oriented with strong written communication — you can explain sophisticated concepts precisely and clearly
• Self-directed and comfortable producing high-quality work i
