Senior Full Stack Software Engineer

Heidi

Heidi is building an AI Care Partner that works alongside clinicians to make healthcare continuous and deeply human. 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.

What You'll Do

• 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.

• 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 organizations operate in practice, especially the requirements and constraints that come with serving US customers, and translate that into product improvements.

What We're Looking For

• 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.
