AI Expert Network connects you with prompt engineering specialists who design, test, and optimize prompts for Claude, GPT, and Gemini. Expect systematic evaluation, prompt versioning, and measurable improvements.
Work with expert prompt engineers. Optimize LLM outputs, design prompt pipelines, and build reliable evaluation systems.
A prompt engineer makes an LLM behave reliably on the same task thousands of times, not just once in a demo. That means structured prompts, versioning, and an evaluation set that catches regressions when a prompt changes.
The job is closer to testing than to writing. The output that matters is a system that stays consistent under real, varied input.
Ask to see their eval harness. Serious prompt work is measured, with a labeled test set and before and after numbers, not adjusted by feel until it looks good.
Ask how they handle the cases where the model gets it wrong, because guardrails and fallbacks separate a production prompt from a lucky one.
Prompt engineers on AI Expert Network charge $60 to $200 per hour. A focused optimization pass on an existing feature is a short engagement, while building a full prompt system with evaluation for an enterprise app is a larger, multi week piece of work.
A prompt engineer designs and optimizes the instructions given to LLMs. Good prompt engineers use evaluation harnesses, A/B testing, and iteration rather than guesswork.
