Job description

Who?

Phoebe is building AI teammates for home health. Done right, this is a chance to build a net-new product category and wedge our way into a huge network-effect business in a large, growing, real-world market.

Why?

• Real Revenue and Traction
  • We are growing fast with paying customers and real revenue
  • Backed by Slow https://slow.co/about/ and other great investors
• Big Market in the Real World
  • As AI continues to accelerate, real-world skilled labor is only going to become more valuable.
  • We are focused on building for the 25B+ US medical staffing market - which is growing fast, and has huge tailwinds as America ages.
  • AI is fundamentally changing how staffing works - creating a clear path to take over the market in this period of change.
  • Building a classic network-effect business - there's a clear story as to how this gets more and more durable and valuable at scale. We're building for the commodified-software world and the strategy reflects it.

Who This Role Is For

You’ll be excited about this if you:

• Are full‑stack and like to learn new skills – prior experience with LLM/AI product development not required, but helpful.
• Ready to ship voice AI features to production in the next 30 days.
• Want to own and run with significant technical decisions, with room to grow into leading technical execution.
• Are energized by working in person.
• Are a product person, and like polished, well‑designed tools – we are going to build one, and prioritize this as we go.
• Excited about exploring the potential to scale companies to huge sizes with small headcounts as AI continues to improve.
• If you do want to found your own company someday – you will have a clear view into engineering, product, go‑to‑market, and the iterative loop that connects all 3.

You won’t like this if:

• Are looking for a clean, siloed engineering job – like most startups, this is too early to join if you want a stable, well‑defined ticket‑execution role.
• Are not excited about building something big, quickly.
• Don’t want to prioritize working in‑person several days a week.

Requirements

• Portfolio of projects (ideally LLM‑based).
• CS degree or dropout.
• NYC or willing to relocate.

About the Founder

I’m Justin Woodbridge – I’m a multi‑time, technical founder. My last startup, Bayes, went through YC in 2019. It was acquired by Airtable in 2021. Before that, I built a bootstrapped fundraising tool that processed >$100M of GMV. I studied CS at Columbia, and live in Brooklyn, NY. Other members of the team include ex‑Airtable engineers and an exited healthcare staffing platform founder.
