What to look for in a Prompt Engineering freelancer
A strong prompt engineer treats prompts like software: measured, versioned, and improved, not guessed. Look for:
- A systematic approach, testing variations against examples rather than tweaking by feel.
- Understanding of model behavior, including context limits, temperature, and where models hallucinate.
- Experience with real APIs: OpenAI, Anthropic, or open models, and the tooling around them.
- Skill at grounding output with retrieval, examples, and structured formats.
- Attention to cost and latency, not just the cleverest possible prompt.
Ask for a before-and-after: a weak prompt, the fix, and how they proved it improved. Good prompt engineers can show the difference, not just claim it.
