Full Stack Engineer

We’re Heidi.

We're building the future of healthcare by giving every clinician the earth's finest AI Care Partner. Our platform has absorbed the administrative chaos of 175 million patient visits and supported 67 million clinical hours. Today, we support 2.8 million patient sessions a week across 190+ countries, in 110 languages and over 200 specialties.

Healthcare systems are failing us; clinicians spend more time on documentation than on patients, and the human connection that makes medicine worth practicing is eroding. Our mission is simple: double the world’s capacity for care and strengthen the human connection at its heart.

We found product-market fit with a freemium medical scribe that clinicians love. Now, we're expanding. Every task a clinician hands to Heidi is a patient who feels more attended to, a health system unclogged, and a clinician who gets to be a clinician again.

We’ve grown annual recurring revenue from $1 million to $50 million in two years.

To go further, we’ve secured US$340 million: a $100 million Series C led by Blackbird, with Phoenix Court, Point72 Private Investments and Headline, alongside a $240 million growth investment led by General Catalyst’s Customer Value Fund.

The role

A Senior Full-Stack Engineer who owns new features end-to-end: the React interface a clinician clicks, the Python service behind it, and the data model underneath. You have shipped SaaS products inside a high-growth startup, and a slow query bothers you as much as a component that drops frames.

You know where the trade-offs live on both sides of the stack: when logic belongs in the browser and when it belongs on the server, and how a schema decision made today shows up as latency on screen in six months.

You take a loose brief and return a working, tested feature without waiting for a hand-off from another team. You read the user need behind the ticket.

You thrive in a flat, flexible team, and you pick up the specifics of building an AI product for clinicians in 190+ countries within your first weeks.

Brilliant people come from unlikely places. If you have a record of shipping hard, technically demanding products and features, whatever the industry, we want to meet you.

What you'll do

You will work alongside the engineers who built Heidi, shipping AI products that change how healthcare runs.

• Own features from database to browser: design the data model, build the Python service, ship the React and TypeScript interface, then watch how clinicians use it and iterate.

• Build fast, accessible interfaces in React, TypeScript and Next.js that hold up for a GP seeing twenty patients before lunch.
