- Produce clear documentation and enable teammates to operate agents safely
Requirements

- Strong prompt engineering experience, including multi-agent setups
- Experience designing evaluations and driving measurable improvements
- Hands-on with agent/prompt/automation platforms (Airtable, Zapier, Latitude, etc.)
