You're a talented Lead Product Designer with a passion for health and excitement about building our expanding healthcare platform. You enjoy working in dynamic environments, solving complex problems, and creating thoughtful, user-centred design solutions that make a real impact.

In this role, you will:

Own a domain, a product line's design, or a system others depend on.
Drive outcomes across the domain, not a single surface. You tie design to revenue, retention and cost, and to outcomes like trust and operational efficiency.
Set the quality bar for a group of designers. You raise it by shipping and by coaching.
Take line management of designers, where the team needs it. You develop people without leaving the craft.

What good looks like

Scope: you own a domain and the system under it.
Impact: you moved domain-level outcomes. Revenue, retention or cost, not just a feature.
Influence: you coach and develop designers, formally or informally. You build coalitions beyond design. The bar rises around you.

About you (who you are)

Skills & experience

Problem definition. You shape problem definition across a domain. With evidence and the input of others, you focus the team on what matters and cut what does not. You turn ambiguity into a plan the team can run.
Visual craft. Non-negotiable, and you set the paradigms and standards the team calibrates to, motion and micro-interactions included.
Accessibility. You set the domain's bar. Compliance is the floor, not the target, and you coach others past checkbox thinking.
Systems thinking. You build the infrastructure. Design systems, information architecture, shared surfaces across mobile and emerging platforms like AI interfaces. You think in service design terms, connecting the app to the clinician and the delivery. The full 360, not just the screen.
Product and commercial sense. You connect design to the numbers that move the business. You bring the patient voice into the room and the commercial case with it.
Communication. You align people. Clear writing, sharp critique, opinions others can act on. What you chose not to do is as clear as what you built, and it closes debates rather than reopening them.
Working in the open. You build the conditions for it. Critique over presentation, rough work shared safely, feedback that makes the work better.

How you work with AI

Advanced prototyping. You test real ideas in real code, fast.
You redesign how your team works with AI, not just your own loop.
You know where AI does not belong, and you hold that line for the team.
You expose weak operating models and fix them. Judgement over production, set as a standard others follow.

The full stack

We expect you to work end to end, from problem definition and research to information architecture and UX writing.

You set the research and experimentation bar for your domain.
You make others better at validation, testing and reading results honestly.
You raise the writing bar. In regulated health, that is craft and compliance at once.
You set the bar for problem definition, especially on the hardest, most ambiguous problems.

Your portfolio

Show problem solving that moved a commercial lever across a broader product area, not a single surface. We want to see the craft, polish and care throughout, how you elevated the people around you and built an inclusive team culture, and how AI reshaped the way your team worked. How you write it says as much as what you show. Concise and clear is a signal of how you communicate. Applications without a portfolio will not be considered.

Experience

Typically 8 years or more in product design, with a track record of owning a domain, building systems others depend on, and developing other designers.

Behaviours & attitude

Patient-first mindset. You put patient outcomes first. Every decision weighs commercial growth against clinical safety and care, and you don't let one erode the other. You understand real health journeys well enough to make them simple, accessible and worth trusting.
Collaborative creation. You work well across product, engineering and clinical, and you know a good idea can come from any of them. You listen to feedback and take it on, using it to make the work better.
Curiosity. You ask why before how. You stay curious about the patient, the problem and the tools you use to solve it, and you're comfortable being a beginner when something new is worth learning.
