Senior Machine Learning Expert

Senior Machine Learning Expert (AI Training) About the Role What if your deep understanding of machine learning could directly influence how the next generation of AI systems reason, plan, and make decisions? We're looking for a Senior Machine Learning Expert to help build the training data that teaches large language models to think more reliably — step by step, in real-world scenarios. This is a fully remote, flexible contract role built for senior ML practitioners who want meaningful, high-impact work on their own schedule. 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 step-by-step thought processes that help AI navigate intricate, real-world problem-solving scenarios Review and mentor the quality of reasoning traces — ensuring logical rigor, clarity, and optimal decision-making documentation Develop data strategies that improve how LLMs handle ambiguity, multi-step reasoning, and tool use Apply senior-level architectural insight to ensure the training data you produce drives more reliable and trustworthy model behavior Who You Are Experienced in machine learning, AI research, or a closely related technical discipline Skilled at decomposing complex problems into clear, structured, logical steps Deeply familiar with how large language models are trained, evaluated, and improved Comfortable thinking rigorously about model behavior, edge cases, and failure modes Detail-oriented with a consistent, methodical approach to quality Able to work independently and asynchronously without hand-holding Nice to Have Prior experience in data annotation, data quality assurance, or AI evaluation systems Top-tier Kaggle competition results (Grandmaster or Master level), demonstrating mastery of model performance and feature engineering Fam
