Senior Machine Learning Expert (AI Training) About The Role What if your deep expertise in 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 Experts to author high-fidelity reasoning traces — the structured, step-by-step records of how an intelligent system should approach and solve complex real-world tasks. This data becomes the backbone of training for frontier LLMs, directly influencing how reliably they reason, use tools, and make decisions at scale.

This is a fully remote, flexible contract role built for senior ML practitioners who want meaningful, intellectually stimulating work at the cutting edge of AI development.

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, reason, and act across sophisticated technical tasks

Design data strategies that enable LLMs to navigate intricate, multi-step real-world decision-making scenarios

Review and mentor structured traces to ensure optimal documentation of planning, tool use, and logical progression

Apply senior-level architectural insight to guarantee consistent, reliable model decision-making patterns





Identify gaps and failure modes in AI reasoning and contribute structured solutions through annotated examples Who You Are Seasoned ML practitioner with significant experience in machine learning, deep learning, or related technical fields

Skilled at decomposing complex problems into clear, logical, well-documented steps

Experienced with advanced LLM evaluation, training methodologies, or model reasoning workflows

Detail-oriented thinker who communicates technical concepts with precision and clarity

Self-directed and comfortable working independently in an asynchronous remote 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 deep expertise in model performance and feature engineering

Familiarity with prompt engineering, chain-of-thought methods, or reasoning trace construction

Background in AI safety, alignment research, or RLHF workflows Why Join Us Work on frontier AI projects in direct collaboration with leading research labs

Fully remote and async — work on your own schedule, from anywhere in the world

Freelance autonomy with intellectually stimulating, high-impact work

Rare opportunity to contribute directly to how the next generation of LLMs learn to reason

Potential for ongoing work and contract extension as recent projects launch
