Senior Software Engineer

Who are we

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

A Senior Software Engineer responsible for the execution of the backend features,  with a deep technical understanding and how it translates to representing user needs. You will have operated in a hyper growth startup with experience building SaaS products. 

You will also have a deep understanding of the key challenges engineers face and a firm grasp on design principles in prioritizing key features and capabilities.

Your superpower is how to bridge the gap between technical specifics and business needs effortlessly and turn high-level designs into real-world solutions. 

You thrive in challenging situations, and you appreciate the dynamics of a flexible, flat-structured work environment. You are quick to grasp the nuances and complexities of developing an AI product healthcare internationally. 

We know that brilliant people can come from unlikely places; if you have a proven track record of shipping spectacular technically challenging products and features, regardless of industry, we want to meet you.
Your team
You'll join a team building the foundation that lets hospitals and healthcare organisations onboard to Heidi in hours, not weeks—with enterprise-grade security their IT teams can trust. Your work enables clinicians to collaborate seamlessly while keeping patient data safe. Every feature you ship strips away admin burden and returns clinicians to their patients.

What you'll do: 

- Build enterprise-grade user management: Develop features that let organisations self-manage their users—provisioning, role syncing from IdPs, team policies, data retention, and MFA enforcement

- Deliver critical auth capabilities: Implement security features like single logout, IdP-initiated logout, idle lock, and session management that enterprises expect

- Design for multi-region scale: Build systems that support data residency requirements and scale reliably as Heidi grows into mid-market and enterprise customers

- Keep patient data secure: Your work directly protects sensitive health information through robust access policies and up-to-date security controls

- Grow with the domain: Start with foundational auth work, then take on increasing ownership of User Management as the team and product evolve

- Ship with quality: Write clean, testable code with strong API design—these systems are depended on by every other team

What we’ll look for: 

- Strong full-stack or backend experience (Python preferred; TypeScript a plus)

- Solid understanding of API design, data modeling, and building secure, reliable services

- Comfortable with distributed systems concepts: multi-region, caching, eventual consistency

- Security-conscious mindset—you think about edge cases, access control, and audit trails

- Track record delivering features independently in a fast-paced environment

- Motivated by building infrastructure that other teams and customers depend on

- Experience with identity or auth systems (SSO, OIDC, SAML, SCIM, MFA) is a plus but not required

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 th
