## About the role

As one of the founding members of Prolific's newly formed AI Data Services team, you'll help build the quality systems behind some of the world's most advanced AI models. Data quality is a strategic priority for Prolific, so this is a high-visibility role with direct exposure to senior stakeholders. This isn't a traditional QA role. We are not looking for someone to review data against a predefined checklist.

## What they're looking for

- Experience with LLM evaluation, RLHF, AI safety or red teaming
- Experience translating vague model or evaluation goals into clear annotation specifications
- Experience working with human annotation programmes or human data operations
- Familiarity with calibration, inter-rater agreement, drift detection or other evaluation methodologies
