Senior Site Reliability Engineer (Upmarket)

Who We Are

Healthcare needs a better rhythm: one that keeps care continuous and deeply human. Heidi is building an AI Care Partner that works alongside clinicians to make that possible.

We’re a team of doctors, engineers, designers, researchers, and creatives building tools that help clinicians stay focused on what matters most: their patients.

In just 18 months, Heidi has given back more than 18 million hours to healthcare professionals — supporting 73 million patient visits in 116 countries. Today, more than two million patient visits each week are powered by Heidi worldwide.

Backed by nearly $100 million in funding, we’re growing in the US, UK, Canada, and Europe, partnering with leading health systems including the NHS, Beth Israel Lahey Health, and Monash Health.

What you’ll do

• Participate in on-call and incident response:

  Respond to production incidents, contribute to service restoration, and support clear communication during incidents. Over time, take increasing responsibility for leading incidents end-to-end.

• Improve operational reliability:

  Identify recurring issues and reliability risks, and drive fixes through better alerting, automation, system changes, or process improvements.

• Own parts of the production environment:

  Operate and improve Kubernetes clusters, cloud infrastructure, and core platform services, with growing ownership as familiarity increases.

• Strengthen observability:

  Improve dashboards, alerts, logs, and traces so issues are detected earlier and diagnosed faster, with a strong focus on actionable signals.

• Reduce operational toil:

  Automate repetitive tasks, simplify runbooks, and improve tooling to make on-call and day-to-day operations easier and safer.

• Support safe change:

  Improve deployments, rollback mechanisms, and operational readiness to reduce the risk of incidents caused by change.

• Contribute to operational practices:

  Write and maintain runbooks, participate in blameless post-mortems, and help improve incident response processes over time.

• Collaborate closely with engineers:

  Work with product and feature teams to improve production readiness, service ownership, and reliability expectations.

What we’re looking for

• 3–6+ years in SRE, DevOps, Platform, or operations-heavy engineering roles.

• Experience supporting production systems and participating in on-call rotations.

• Comfortable debugging live systems under pressure.

• Experience operating cloud infrastructure (AWS preferred).

• Working knowledge of Kubernetes and containerised workloads.

• Infrastructure as Code experience (Terraform or similar).

• Familiarity with monitoring and alerting tools (Datadog, Prometheus, etc).

• Scripting or automation experience (Python, Bash, or similar).

The way we work

1. Build to Last

We design for safety and reliability so clinicians, patients, and our teams can trust what we build every day.

2. Own Your Practice

Ideas rise on merit, not title, and everyone shares responsibility for the standards we set together.

3. Move Fast, Stay Steady

We move quickly but never at the cost of trust. Progress only matters if people can depend on what we make.

4. Make Others Better

Honest feedback, steady support, and shared growth keep our teams improving together.
