Product Designer in London

We're building the future of healthcare by giving every clinician the earth's finest AI Care Partner. In just 18 months, our clinical AI products 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're looking for a product designer who designs, prototypes, and ships. Someone who knows the difference between software that works and software that makes someone smile. Clinicians use Heidi to get away from keyboards and back to patients. We want the product to feel as considered as the best software you've ever used: cohesive, quiet, and precise across every surface. When a clinician's tools feel right, they spend less time fighting software and more time with patients.

You'll own specific features across Heidi's product surface, from the first rough frame through to what lands in front of clinicians. You'll work directly with engineers, care about the 3px padding issue as much as the information architecture, and ship work you're proud of, not just work that passes review.

What you'll do:

• Produce pixel-precise, interaction-complete work you'd put in your portfolio, not work that just clears the bar.
• Use AI tools as part of your process: generating variants, accelerating exploration, moving from rough concept to refined solution faster than traditional workflows allow.
• Work directly with engineers during implementation, reviewing builds and flagging where quality has slipped from the spec.
• Sweat the details that separate good software from trusted software: type choices, spacing, motion, micro-interactions.
• Work within and contribute to the design system: apply existing patterns with rigour, flag where patterns are missing or broken.
• Share work early, give honest critique, and receive feedback with the same seriousness you'd give it.

What We're Looking For:

• A portfolio that shows craft at the component and screen level. We want to feel something when we look at it, not just follow the UX flow.
• You use AI tools (Figma AI, Claude Code, or similar) as part of your workflow: regularly and with intent, not occasionally.
• Strong foundational skills: typography, layout, colour, component architecture. The kind of thing you can see immediately in someone's work.
• You can defend a design decision without referencing user testing; you have opinions about easing curves, optical versus mathematical alignment, and why a component should be structured the way it is.
• When you see a broken pattern in production, your instinct is to fix it, not file a ticket.

How we show up:

• Build for the next decade, not next quarter. Our targets are outrageous on purpose.
• Lead, don't wait. We treat tomorrow's problems today.
• Follow the evidence. Trust the patient. We pursue truth relentlessly.
• Own the outcome. Everyone here carries the company.
• Ship, measure, go again. More iterations beat better planning.
• Live in clinicians' reality. We build for exhausted humans.

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. 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.

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.
