Project Lion - Prompt Engineer - United States (Remote, Part-Time)

We are seeking a Prompt Engineer tobe responsible forthe end-to-end technical migration workflow for transitioning templates to LLMautoraters.The role isrequiredto use client’s internal tools toleverageprompt engineering techniques to maximize model performance.

Responsibilities:

• UtilizeAutomatic Prompt Generation (APG) tools to create baseline prompts for complex parent-child template clusters.
• Run and superviseAutomatedPrompt Optimization (APO) tool,review the outputs, and flag when the APO reaches deadlocks or plateaus.
• Manuallydraft, test, and refineprompts 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.
• Monitorshadowbotruns to ensure sufficient disagreements(between human and LLM ratings) are registered, generated, and tracked.
• Runprompt versions against establishedgold datato continuously measureautoraterquality against the human crowd baseline, calculatingaccuracymetrics such as F1 scores, precision, and recall.
• Drafttechnical launch readiness justifications (Launch Certification Documentation) for final.

Requirement:
