    • Manually draft, test, and refine prompts to navigate complex template architectures, overcome anti-patterns, and handle edge cases where tooling is lacking or broken. Solve edge-case scenarios by designing and refining manual prompts. 

    • Monitor shadowbot runs to ensure sufficient disagreements (between human and LLM ratings) are registered, generated, and tracked.   

    • Run prompt versions against established gold data to continuously measure autorater quality against the human crowd baseline, calculating accuracy metrics such as F1 scores, precision, and recall.

    • Data Analysis: Strong proficiency in identifying error patterns, analyzing model performance, and using SQL or other data analytics tools.  

    • Technical Agility: Ability to quickly learn and master proprietary tools with minimal supervision.  

    • Communication: Excellent verbal and written communication skills.  

Optional / Preferred Skills:  

    • Familiarity with enterprise-grade LLM interfaces like the Goose API.
