Prompt Engineer
Evolvingengineering
Prompt Engineers specialize in crafting, testing, and versioning the prompts that drive production AI systems. They build evaluation frameworks to measure prompt quality, run systematic A/B tests across different prompt strategies, and maintain prompt libraries that other teams consume. As the field matures, this expertise is increasingly folded into AI Engineer and AI Product Manager roles rather than standing alone.
Salary by Level
A Day in This Role
The day begins by reviewing overnight evaluation results comparing prompt variants across different model versions. Late morning is spent pair-programming with the AI engineering team to integrate a new chain-of-thought prompting strategy into the production pipeline. The afternoon involves documenting prompt patterns in the team's internal library and running red-team tests to find edge cases where prompts produce unsafe or incorrect outputs.
Common Interview Topics
- 01Design an evaluation framework to compare two prompt strategies for a customer-facing summarization feature — what metrics matter and how do you collect ground truth?
- 02Walk through how you would systematically red-team a prompt to find failure modes before production deployment
- 03Describe your approach to prompt versioning and rollback when a new prompt degrades output quality
- 04How would you optimize a chain-of-thought prompt that produces correct answers but is too slow and expensive for real-time use?
- 05A prompt that works well on GPT-4 performs poorly on Claude — describe your cross-model prompt portability strategy
