Alignerr Corp.; Województwo mazowieckie; Remote; PLN 83,000 - 124,000; Part time

Job summary

Alignerr is seeking experienced ML engineers to evaluate AI-generated machine learning solutions from Warsaw and across Poland. This fully remote, flexible hourly contract lets you work on your own schedule, without fixed hours, focusing on catching errors and improving model quality.

You will review code across Python ML frameworks, write high‑quality ML solutions, and craft clear explanations for model decisions, enabling frontier AI models to perform better at one of the hardest tasks they do.

Qualifications

• Deeply fluent in machine learning — model development, data preprocessing, training pipelines, and deployment
• Hands-on experience with ML frameworks such as TensorFlow, PyTorch, or scikit-learn
• Strong written communicator — able to explain complex ML concepts clearly and precisely
• Detail-oriented and rigorous — you catch what others miss and care about getting things right
• Self-motivated and comfortable working independently in an async environment
• 3–5+ years working on ML projects, pipelines, or MLOps
• Experience with model evaluation, cloud deployment, or production ML systems
• Background in data labeling, RLHF, or other AI training workflows
• Prior experience with code review or technical writing

Responsibilities

• Review and evaluate AI-generated machine learning code — including Python, TensorFlow, PyTorch, and scikit-learn — for correctness, efficiency, scalability, and clarity
• Write high-quality ML solutions to modeling, data processing, and deployment problems across a range of difficulty levels
• Craft clear, developer-friendly explanations for model architecture decisions, code logic, and problem-solving approaches
• Identify edge cases, ambiguities, and weaknesses in problem statements, datasets, or AI-generated responses
• Help set the quality bar for how AI understands and produces machine learning code
