Software Engineer (Integrations) | HL7 / FHIR in London

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 in our Integrations Engineering team, you’ll play a key role in connecting Heidi to healthcare systems for the UK&I. You’ll design and implement integrations with EMRs/EHRs and healthcare APIs, ensuring our technology fits seamlessly into clinical workflows. This is a chance to make a direct impact on how clinicians use AI at the point of care.

What you’ll do

• Build and maintain integrations between Heidi and healthcare systems, following interoperability standards like HL7, FHIR, SMART on FHIR.
• Collaborate with our AI/ML team to bring medical speech transcription and note generation into clinical workflows.
• Work with APIs and distributed systems that power Heidi’s core features, ensuring performance, security, and scalability.
• Improve the reliability and accuracy of medical documentation pipelines.
• Champion best practices for building robust, maintainable systems in healthcare contexts.

What we’re looking for

• 5+ years of professional software engineering experience.
• Prior experience integrating with healthcare systems (Cliniko, Halaxy, MediRecords, Epic, Cerner, athenahealth, Meditech, etc.).
• Familiarity with healthcare interoperability standards (FHIR, HL7, SMART on FHIR, etc.).
• Proficiency in a prominent programming language such as Python, C++, Rust, C#, Java, Javascript, Typescript, etc., with experience building APIs and backend services (preferably with FastAPI).
• Experience working with datastores such as MongoDB and Redis.
• Experience with integration design, including RESTful APIs, authentication/authorization (OAuth2, OpenID Connect), and event-driven systems.

Bonus points

• Previous experience in digital health startups or companies building EHR/EMR solutions.
• Knowledge of medical terminology or curiosity about speech-to-text systems.
• Full-stack experience with backend services (Python, FastAPI) and frontend frameworks (React.js) is a plus.
• Passion for improving healthcare and clinician experience.

What do we believe in?

• 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.
