Job Description

We're Heidi.

We're building the future of healthcare by giving every clinician the earth's finest AI Care Partner. In just 18 months, our clinical AI products have absorbed the administrative chaos of 73 million patient visits. Today, we support over 2.5 million patient sessions a week across 190+ countries.

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 healthcare capacity 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.

If you don't choose easy and you want to build something way bigger than yourself then, choose the challenge, choose Heidi.

The role

A clinician mid-visit does not care which region an availability zone sits in. They care that Heidi is there when they press record, and that the note is waiting when they finish. Two million patient visits a week now depend on that being true.

This role leads the team that makes it true. You'll own Heidi's cloud platform and our reliability practice as one function: the infrastructure everything runs on, the SLOs we hold ourselves to, the on-call rotation that answers when they slip, and the tooling that lets every engineer at Heidi ship without filing a ticket. You'll lead a small team of cloud and reliability engineers, and you'll still be close enough to the systems to be useful at 3am.

What you'll do

Lead and grow the platform team covering cloud infrastructure and reliability. Set direction, run hiring, coach engineers through hard technical calls and make sure the on-call load is sustainable rather than heroic.

Own Heidi's multi-region cloud footprint end to end: compute, networking, data stores, Kubernetes, identity and the infrastructure-as-code that defines all of it. Clinical data lives in-region, and your architecture is what keeps that promise across the US, UK, Canada, Australia and Europe.

Set the reliability bar and hold it. Define SLIs and SLOs with the product teams that own each service, run error budgets that actually change roadmap decisions, and report honestly when we spend one.

Run incident response and make it better every time. Own severity definitions, escalation paths, comms to health system customers during an outage, and blameless post-incident reviews where the follow-ups get finished.

Partner with the Release Manager and engineering leads to sharpen how Heidi ships: feature flags, canary and staged rollouts, and rollback paths that get exercised before they're needed. Move deployment frequency and change lead time without moving change failure rate.
