Senior Machine Learning Expert

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.

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

• 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, and 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

• Experienced machine learning professional with a strong foundation in model reasoning, training pipelines, or AI systems design
• Skilled at decomposing complex technical problems into clear, logical, well-documented steps
• Familiar with how large language models are trained, evaluated, and improved
• Detail-oriented - you notice when a reasoning chain breaks down or when a decision step is unclear or missing
• Comfortable working independently and asynchronously, producing high-quality work without hand-holding

• Prior experience with data annotation, data quality assurance, or AI evaluation systems
• Top-tier Kaggle competition results (Grand master or Master level), demonstrating elite model performance and feature engineering skills
• Hands-on experience designing or auditing LLM evaluation frameworks
• Background in AI safety, alignment research, or model interpretability

• Work on some of the most technically challenging AI training projects in the field, alongside leading research labs
• Fully remote and asynchronous - work when and where it suits you, on your own schedule
• Freelance autonomy with access to meaningful, senior-level technical work
• Make a direct, lasting impact on how the world's most advanced AI models reason and act
• Potential for ongoing work and contract extension as new projects launch
