Job description
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 reason, plan, and solve complex problems? We're looking for Senior Machine Learning Experts to help train cutting-edge large language models — teaching them to think step by step, use tools effectively, and make reliable decisions in real-world scenarios.
This is a fully remote, flexible contract role built for senior-level ML practitioners who want to work on some of the most technically challenging and consequential AI problems being tackled today.
- 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 plans, uses tools, and makes decisions step by step
- Design and document structured reasoning workflows for sophisticated real-world technical tasks
- Review and mentor reasoning trace quality to ensure clarity, logical consistency, and optimal decision-making patterns
- Develop data strategies that help LLMs navigate intricate, multi-step problem-solving scenarios
- Apply senior-level architectural insight to ensure the data you produce drives reliable, trustworthy model behaviour
Who You Are
- Experienced machine learning practitioner with significant hands-on expertise in ML, AI, or closely related technical fields
- Skilled at decomposing complex problems into clear, logical, well-documented reasoning steps
- Familiar with advanced LLM evaluation and training methodologies
- Sharp analytical thinker who can bridge deep technical knowledge with structured written communication
- Self-motivated and reliable when working independently and asynchronously
Nice to Have
- Prior experience with data annotation, data quality assurance, or AI evaluation systems
- Top-tier Kaggle competition results (Grandmaster or Master level), demonstrating elite-level model performance and feature engineering expertise
- Familiarity with reasoning trace construction, chain-of-thought prompting, or tool-use training pipelines
- Background in applied AI research or production ML systems
Why Join Us
- Work on some of the most technically advanced AI training projects in the industry alongside leading research labs
- Fully remote and asynchronous — work when and where it suits you
- Freelance autonomy with meaningful, intellectually stimulating work
- Direct impact on how next-generation AI models reason and behave in the real world
- Potential for ongoing work and contract extension as new projects launch
