Senior Software Engineer (Fullstack - Growth)

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.

The Role

Working closely with our Engineering Manager and Growth Product Manager, you'll be a Senior Full Stack Engineer owning end-to-end development of high-impact features in our Growth Team.

What you’ll do:

• Own and ship full-stack features: We’re looking for someone to fully own growth related features end-to-end; working closely with your EM and PM to build and launch full-stack features across both frontend and backend APIs

• Champion quality: author tests, monitor performance and create run-books so teams can trust every release.

• Collaborate cross-functionally: pair with product, design and AI teams to convert ideas into customer value in weeks, not quarters.

• Continuously improve: profile bottlenecks, tune cloud resources and refine developer tooling to keep the stack fast, safe and cost-effective.

What we will look for:

• You’ve started a project from scratch - maybe as a founder, project owner, or by building an impressive side product

• A love for making simplicity out of complexity with an obsession for shipping world-class products

• Deep experience with modern TypeScript on both client (React, Next.js or similar) and server (Node.js, NestJS, Express, etc.).

• Solid backend fundamentals—REST/GraphQL design, domain-driven architecture, relational and NoSQL datastores.

• Cloud proficiency (GCP or AWS): containers, CI/CD, infrastructure-as-code, observability and security best practices.

• Strong testing and code-review discipline, with an eye for readable, approachable code.

• Clear communication & teamwork skills, especially when blocked

• Bonus points: familiarity with real-time streaming, event-driven systems, or integrating AI/LLM services.
