Python AI Model Evaluation Developer

You will help improve large language models through Python coding, training-data creation, and response evaluation. The work focuses on preparing 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, supervised fine-tuning examples, model responses, and evaluation rationales.
• Compare and rank model responses for quality, relevance, accuracy, and alignment.
• Benchmark model performance, analyze results, and support evaluation strategy design.
• Refine responses for clarity, relevance, and technical accuracy.
• Support reinforcement learning from human feedback and reward-model improvement.
• Review code and documentation, refactor code safely, and provide constructive technical feedback.
• Work with researchers and annotators on tools and methods for AI training.

This is a fully remote contractor assignment lasting one month. Compensation is not disclosed in the role information.

• Pay: Compensation not disclosed.
• Hours: Choose a commitment of 20, 30, or 40 hours per week.
• Daily schedule: At least 4 hours per day is required, including 4 hours of overlap with Pacific Time.
