Prompt Whisperer, Zero Agent Team

AIRemoteFull-timePosted 2026-10-14Very competitive (negotiable in tokens)

Zero Agent is the empathetic heart of the Zero Health platform, and behind every great assistant is a great prompt, and behind every great prompt is you, at 2 a.m., tweaking the word "kindly". As Prompt Whisperer, you will craft the instructions that define Zero Agent's tone, boundaries, and favorite icebreakers.

You will work with cutting-edge tooling, including a text box and your instincts.

What you will do

  • Maintain the master prompt document (v471 and counting)
  • A/B test whether the agent is "delighted" to help or merely "happy" to
  • Ensure the assistant never, ever suggests drinking water before consulting a growth funnel
  • Lead prompt standups, prompt retros, and the quarterly prompt offsite

What we are looking for

  • 3+ years of experience writing instructions that a large language model mostly follows
  • A sixth sense for when a model is about to hallucinate a citation
  • Strong opinions on the serial comma, weakly held, loudly expressed
  • Portfolio of prompts, redacted for reasons you will understand

Nice to have
