Prompt Engineer Resume Example

“Prompt engineer with 3+ years optimizing LLM performance through systematic prompt design, evaluation, and optimization. Expert in chain-of-thought prompting, few-shot learning, and building robust evaluation frameworks that ensure consistent AI output quality across production applications.”

• Optimized prompt chains for the customer service AI. Resolution accuracy went from 72% to 91% and average response tokens dropped 40%
• Built a prompt evaluation framework testing 500+ variations across 20 use cases. Made optimization repeatable instead of trial and error
• Designed chain-of-thought strategies for financial document analysis. Hit 95% accuracy on complex multi-step reasoning tasks
• Ran the red teaming program testing AI safety across 200+ adversarial scenarios. Found and fixed 50+ prompt injection vulnerabilities
• Created a prompt template library and guidelines used by 30+ engineers. Standardized how we integrate LLMs across the org
• Responsible for tracking LLM costs per feature and recommending when to use cheaper models versus when quality requires the best
• Worked with the product team to define what good AI output looks like for each use case. Wrote evaluation rubrics
• Tested prompts across multiple models (GPT-4, Claude, Gemini) to understand performance differences and pick the right one per task
• Maintained a regression test suite for prompts so model provider updates didn't silently break our outputs
