About the Role
What if your deep expertise in machine learning could directly determine how the next generation of AI systems reason, plan, and make decisions? We're looking for Senior Machine Learning Experts to author the high-fidelity reasoning traces that teach large language models how to think — step by step, decision by decision.
This is a fully remote, flexible contract role built for experienced ML practitioners who want to work at the frontier of AI development. Your work won't just support AI research — it will actively shape how models reason through complex, real-world problems.
- 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 across sophisticated technical tasks
- Design and document structured decision-making workflows that reflect senior-level architectural thinking
- Review and provide expert feedback on reasoning traces produced by other contributors to ensure clarity, logical rigor, and quality
- Develop data strategies that help LLMs navigate intricate, multi-step real-world scenarios
- Collaborate with a global team working directly alongside leading AI research labs
- Complete task-based assignments independently and asynchronously on your own schedule
Who You Are
- Experienced in machine learning, AI research, or a closely related technical field — you've worked with models at depth, not just in theory
- Skilled at decomposing complex problems into clear, structured, logical steps that others can follow and models can learn from
- Familiar with advanced LLM evaluation and training methodologies
- Detail-oriented and rigorous — you hold yourself to a high standard of technical accuracy
- A clear communicator who can translate expert-level reasoning into well-documented, readable traces
- Comfortable working independently with minimal supervision in an async environment
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 exceptional model understanding and feature engineering
- Background in ML infrastructure, model architecture, or reinforcement learning
- Experience mentoring or reviewing technical work produced by other contributors
Why Join Us
- Work directly on cutting-edge AI projects in collaboration with the world's leading research labs
- Fully remote and flexible — structure your hours around your life, not the other way around
- Freelance autonomy with the depth and meaning of high-stakes technical work
- Make a tangible, lasting impact on how AI models reason and behave in the real world
- Potential for ongoing work and contract extension as new projects launch
