Senior Software Engineer

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 UK healthcare system is defined by its friction - complex billing requirements, rigid EHRs, and administrative burden that pulls clinicians away from patients.

We're looking for a Senior Software Engineer to turn that friction into flow.

You'll build the systems that make Heidi feel native to American healthcare. That means going deep into the infrastructure clinicians actually use and making Heidi work seamlessly inside those workflows. It means building AI systems that handle the complexity of UK billing so clinicians don't have to.

You'll work across the full stack of what makes Heidi valuable in the US market: from the AI pipelines that understand clinical documentation to the integrations that put the right information in the right place at the right time.

This isn't just localisation. It's building the definitive clinical AI experience for the world's most demanding healthcare market.

• Build systems that live inside clinical workflows: You'll shape how Heidi integrates with the EHRs that run American healthcare. The goal isn't connectivity—it's making Heidi feel like a native capability, not a plugin.

• Turn clinical complexity into simple experiences: US healthcare has layers of billing rules, compliance requirements, and payer constraints. You'll build systems that absorb that complexity so clinicians never see it.

• Build for trust and quality: Write clean, testable code with strong interfaces, thoughtful error handling, and observability. These workflows are depended on by clinicians, operators, and downstream systems.

• Own outcomes, not just code: You'll care about whether the things you build actually help clinicians and improve practice revenue—not just whether they technically work.

• Ship agentic workflow functionality: Build systems where AI assists with extraction, reconciliation, and drafting across workflows, with human review, auditability, and clear controls.: Build systems where AI assists with extraction, reconciliation, and drafting across workflows, with human review, auditability, and clear controls.

• Operate in close collaboration: Work day-to-day in a highly collaborative environment, including frequent pairing and shared ownership of design and implementation.

• Grow with the domain: Learn how healthcare organisations operate in practice, especially the requirements and constraints that come with serving US customers, and translate that into product improvements.

• 5+ years of software engineering experience, with a track record of shipping complex systems that real users depend on.

• Strong full-stack fundamentals and experience contributing to user-facing products end-to-end.

• Sound engineering judgment: You make sensible trade-offs, keep scope clear, and improve quality through testing, readable code, and thoughtful design.

• Ownership and follow-through: You take responsibility for what you commit to, communicate clearly when something changes, and unblock yourself or escalate early.

• Collaborative working style: You work well with others, enjoy building in a tight feedback loop, and are comfortable pairing and sharing work in progress.

• Comfort with ambiguity: You can engage with messy problems, ask good questions, and drive toward a practical, shippable solution.

• Fluency with AI coding tools: You use modern AI tools to accelerate delivery, while staying rigorous about correctness and validation.

• Experience with agentic frameworks, modelling complex domains, orchestration, and event-driven architectures is a plus.

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.

• Real product momentum. We’re not trying to generate interest, we’re channeling it. This is a rare chance to create a global impact as you immerse yourself in Australia’s fastest growing start-up.

• Equity from day one. When Heidi wins, you win. You’ll share directly in the success you help create.

• Unmatched impact. Play a pivotal role at a critical growth moment - all while working on a product that delivers tangible value to clinicians and patients every day.

• Work alongside world-class talent. Join a team of operators and builders who’ve scaled unicorns.

• Global reach. Help shape our international expansion as we bring Heidi to key international markets.

• Growth and balance. Enjoy a personal development budget, dedicated wellness days, subsidised gym membership, and your birthday off to recharge.

• Flexibility that works. A hybrid environment, with 3 days in the office.

Heidi is dedicated to creating an equitable, inclusive, and supportive work environment that brings people together from diverse backgrounds, experiences, and perspectives. Our strength is in our differences. We're proud to be an equal opportunity employer and are proud to welcome all applicants as we're committed to promoting a culture of opportunity for all.

Help us reimagine primary care and change the face of healthcare in Australia and then around the world.
