Senior Software Engineer

Overview

Heidi is building an AI Care Partner that supports clinicians every step of the way, from documentation to delivery of care. We exist to double healthcare’s capacity while keeping care deeply human. In 18 months, Heidi has returned more than 18 million hours to clinicians and supported over 73 million patient visits. Today, more than two million patient visits each week are powered by Heidi across 116 countries and over 110 languages. Founded by clinicians, Heidi brings together clinicians, engineers, designers, scientists, creatives, and mathematicians, working with a shared purpose: to strengthen the human connection at the heart of healthcare. Backed by nearly $100 million in total funding, Heidi is expanding across the USA, UK, Canada, and Europe, partnering with major health systems including the NHS, Beth Israel Lahey Health, MaineGeneral, and Monash Health, among others. We move quickly where it matters and stay grounded in what’s proven, shaping healthcare’s next era. Ready for the challenge?

The Role

Working closely with our Engineering Manager – Agents & Automations, you’ll be a Senior Software Engineer – DevOps who keeps our AI-powered systems running smoothly.

What you’ll do

- Own the release pipeline – automate build, test and deploy steps so new models and services reach production quickly and safely.
- Operate cloud infrastructure (GCP or AWS) using Terraform or similar, balancing performance (e.g. GPUs, specialised CPUs) with cost.
- Build sensible observability – surface metrics for model-level latency, token usage and streaming throughput alongside traditional health checks.
- Manage artefacts – handle model weights, embeddings and audio assets so versions are traceable and rollbacks painless.
- Harden security – apply least-privilege principles, secrets management and data-handling policies suited to sensitive health data.
- Guide the team – create runbooks, share best practices and help engineers debug production issues.

What we will look for

- Strong foundation in Linux, containers and networking.
- Hands-on experience with IaC (Terraform, Pulumi or similar) and at least one major cloud platform.
- CI/CD expertise covering microservices and workloads that include GPUs or other specialised hardware.
- Working knowledge of monitoring and alerting stacks (Prometheus, Grafana, Cloud native tools) with an eye on AI-specific signals such as model response times and cost per request.
- Comfort navigating security and compliance in a data-sensitive environment.
- Clear communication; you make complex infra topics accessible to the rest of engineering.
- N/A Nice to have: exposure to streaming media, real-time inference pipelines or running large-language-model services in production.

Attitude is more important than experience so if you are a hungry, competitive and highly motivated operator who has a knack for problem solving and building relationships, we want to hear from you.

What do we believe in?

Heidi builds for the future of healthcare, not just the next quarter, and our goals are ambitious because the world’s health demands it. We believe in progress built through precision, pace, and ownership.

- Live Forever - Every release moves care forward: measured, safe, and built to last. Data guides us, but patients define the truth that matters.
- Practice Ownership - Decisions follow logic and proof, not hierarchy. Exceptional care demands exceptional standards in our work, our thinking, and our character.
- Small Cuts Heal Faster - Stability earns trust, speed delivers impact. Progress is about learning fast without breaking what people depend on.
- Make others better - Feedback is direct, kindness is constant, and excellence lifts everyone. Our success is measured by collective growth, not individual output.

Our mission is clear: expand the world’s capacity to care, and do it without losing the humanity that makes care worth delivering.
