Senior Design System Engineer

We’re Heidi.

We're building the future of healthcare by giving every clinician the earth's finest AI Care Partner. In just 18 months, our AI products (Scribe, Comms, Evidence, Remote) have absorbed the administrative chaos of 73 million patient visits. Today, we support over 2.5 million patient sessions a week across 190+ countries.

Healthcare systems are failing us; clinicians spend more time on documentation than on patients, and the human connection that makes medicine worth practicing is eroding. Our mission is simple: double the world’s healthcare capacity and strengthen the human connection at its heart.

We found product-market fit with a freemium medical scribe that clinicians love. Now, we're expanding. Every task a clinician hands to Heidi is a patient who feels more attended to, a health system unclogged, and a clinician who gets to be a clinician again.

If you want to build something way bigger than yourself, jump in.

What You'll Do

• Build and own Heidi's design system across React and Figma. This is the component library, tokens and patterns every product team builds on, so a button behaves the same whether it ships in Scribe, Evidence or Comms.

• Shape where the product is heading, not just how it's built. You'll bring real product design taste to the system and push the bar on what good looks like across the app.

• Set and defend the standards for design and frontend: accessibility, component API design, and how a Figma file becomes shipped code without drifting along the way.

• Embed with product pods during feature work, helping engineers and designers get from mockup to merged PR without rebuilding the same primitives every sprint.

• Improve developer experience for everyone building on the system. That means monorepo structure, giving our AI coding tools the context they need to generate on-brand frontend, and cutting the small frictions that slow design-to-code down.

What We're Looking For

• You've built or owned a production design system in React, not just consumed one. Component libraries, design tokens, theming, the works.

• You're fluent in Figma as a systems tool: variables, component properties and keeping the design source in sync with the code.

• Strong frontend engineering with TypeScript and modern React, plus a clear point of view on component API design that you can defend.

• Genuine product design sense. You can look at a screen, know why it feels off and fix it, rather than only implementing someone else's spec.

• You've worked inside a monorepo and improved the tooling around it, whether that's build speed, linting or frontend CI.

• You've shipped things that made other engineers faster, and you treat developer experience as part of the job rather than a side project.

It would be great if you also have: deep accessibility (WCAG) experience, a track record of setting up AI coding tools to produce on-brand frontend, or time building in healthtech or another regulated, high-trust domain.

How we show up

• Build for the next decade, not next quarter. Our targets are outrageous on purpose. The world's health doesn't have the luxury of incrementalism.

• Lead, don't wait. We treat tomorrow's problems today. Sometimes we build what's needed before it's wanted, and we're fine with that.

• Follow the evidence. Trust the patient. We pursue truth relentlessly. But when the subjective and objective disagree, we treat the patient, not the numbers. Ego is a comorbidity we can't afford.

• Own the outcome. Everyone here carries the company. Raise problems with solutions, solve them end-to-end, and never be a bystander.

• Ship, measure, go again. A button today, a workflow tomorrow. More iterations beat better planning. We're precise at pace, not reckless.

• Live in clinicians' reality. Not the ideal workflow, the twenty-patients-before-lunch actual one. We build for exhausted humans, and we'd better be decent ones while we do it.

Why Heidi?

You’ll join a team focused on real-world impact over imaginary valuations and glossy PR. We live and breathe the challenges of modern health systems, and are laser-focused on exacting the change we’d like to see. We’re medicos, engineers, builders, and designers who’ve felt (on every side of the equation) what non-care feels like—the moral and practical toll as a provider or receiver.

Building what we’re building isn’t always easy. But we didn’t choose easy, we chose to build something that actually matters. We hold ourselves to a higher standard because healthcare demands it. If you join Heidi, you recognise that the deeper question isn’t whether AI can solve the global healthcare crisis, but whose hands will shape it. The work is hard, but you will trust and admire the people you work beside, and rest easy knowing you’re doing the defining work of your career.

True A-players progress extremely fast here. The nature of the scale-up game is demanding, but we value sustainable performance and mental health. You're trusted to perform, and you set your schedule. We operate on outcomes > inputs, not process theatre. We all take the bins out, metaphorically and literally.

We take care of you.

We offer a $1,000 annual learning and development budget, a $150/month health and wellness allowance, a $500 home office budget, 26 weeks paid primary parental leave and 18 weeks paid secondary parental leave, fertility support up to $10,000, four weeks of work from anywhere per year, and serious equity.
