Senior Python Developer (AI Model Evaluation)

You will help improve large language models through coding, training-data creation, and response evaluation. The work focuses on producing and reviewing examples rather than building or fine-tuning the models themselves.

• Write and maintain efficient Python code for AI training and evaluation workflows.
• Create Python solutions, model responses, supervised fine-tuning examples, and evaluation explanations.
• Compare and rank model responses for quality, relevance, accuracy, and alignment.
• Test model performance, analyze results, and suggest ways to improve quality.
• Refine responses for clearer language, stronger relevance, and technical accuracy.
• Review code and documentation, design evaluation approaches, and give constructive technical feedback.
• Support reinforcement learning from human feedback and reward-model improvement work.
• Work with researchers and annotators while exploring tools and methods for stronger AI training processes.

Compensation is not disclosed for this assignment. It is a fully remote contractor role lasting one month.

• Time commitment: at least 20 hours per week and at least 4 hours per day.
• Available commitments: 20, 30, or 40 hours per week.
• Schedule: at least 4 hours of overlap with Pacific Time.
• Location: open worldwide and fully remote.
• Language: fluent conversational and written English.
• Experience: at least three years of strong Python programming experience.
• Technical skills: familiarity with Python frameworks and libraries, software-development quality standards, formatting, architecture, and best practices.
• Testing: experience with unit, integration, and property-based testing in Python.
• Programming knowledge: understanding of multithreading and asynchronous programming.
• Problem solving: ability to refactor code safely, avoid regressions, and diagnose memory or concurrency issues.
• Communication: ability to write clear evaluation explanations and technically accurate responses.
