Senior Software Engineer (Fullstack - Enterprise Foundations)

Who are Heidi?

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

We’re looking for a Senior Full Stack Engineer with strong leadership skills to help shape and deliver world-class user experiences in our AI-powered healthcare products.

You’ll be comfortable working across the stack, but have a particular interest in crafting elegant, intuitive, and performant interfaces. You combine technical depth with a product mindset — thinking not only about how features are built, but why they matter, and how they can best serve our users.

What you’ll do:

• Lead development of foundational systems: We’re looking for someone to lead the design and development of key systems such as authentication across all of Heidi’s platforms; working closely with other teams and stakeholders to build systems that enable other teams and the product roadmap.

• Champion quality & maintainability: design simple and maintainable systems to solve complex problems, author tests, optimise performance and create fault tolerant systems so teams can move fast without compromising quality.

• Continuously improve: drive continuous improvement by providing technical leadership and mentorship, identifying process or development bottlenecks, and working with our AI enablement team to improve both the speed and safety with which we release.

What we will look for:

• 5+ years experience working on complex, high-scale, or highly integrated services, with the ability to work effectively on both frontend (TypeScript, React) and backend (Python or TypeScript) services. Experience with REST/GraphQL design, domain-driven architecture, relational and NoSQL datastores.

• Strong communication and collaboration skills, with the ability to work effectively in a cross functional team, balance priorities from other departments and coordinate the release of your team’s features.

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

• A proven history of architecting and building highly available, scalable, secure & performant systems.

• A product mindset — you care deeply about solving real problems for users and measuring the impact of what you build.

• Bonus: Experience with authentication and identity platforms is a strong plus, especially with good understanding of security concerns and best practices across APIs, web and native/mobile.

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.
