About the role

Our mission is to help small businesses run themselves. We’re starting with doctors’ offices, building autonomous systems that handle busywork and complete the workflows that keep the office moving every day. Our team is small, flat, and ambitious. We value craft, intellectual rigor, and direct communication.

About the Role

We're hiring a design-minded engineer to build the control plane for powerful agents handling billing and medical records. Real patients and real practices depend on these systems. You'll craft interfaces that make autonomous agents feel trustworthy and effortless to supervise.

We take a consumer approach to healthcare software: approachable, elegant, and sweating the details. The product spans onboarding, human-in-the-loop review, the tools practice owners use to understand their business, and more.

You Will Be a Great Fit If You

  • Strive for great, not good, and iterate until you get there
  • Take pride in building software that feels fast and effortless
  • Look for leverage: using tools, automation, and process to multiply your impact
  • Have strong fundamentals in JavaScript and browser APIs
  • Believe healthcare software should be as delightful as consumer products

Some Things We've Built

  • A sync engine backed by encrypted SQLite in the browser, enabling 100ms experiences for healthcare payments and patient ledgers
  • Systems that eliminate thousands of hours of paperwork every month
  • Data pipelines processing $1B+ in insurance claims

Technology We Use

We invest heavily in productivity. Engineers should have the best tools for the job and the freedom to choose them.

  • TypeScript, React, Tailwind
  • Python (Django, Pydantic AI), Postgres, Redis
  • Google Cloud Platform, Vercel
  • Linear, Slack, Notion

Joining US

To start, you'll have a handful of conversations with our team and founders. If there is mutual excitement, we'll invite you to the office where you'll work on a small project and meet the team.
