Job description

I’m partnering with a wellness organisation going through a major product transformation — shifting from a traditional health club model into a fully‑fledged, data‑driven wellness and longevity platform.

Right now, there’s no unified digital experience across web or app, which creates a genuinely greenfield opportunity. A full website rebuild (new tech stack and front‑end) will be underway alongside a broader app redesign — but the real challenge sits deeper: defining how data becomes meaningful to users.

This is where you come in.

At the heart of this role is a critical workstream focused on longevity, health data, and performance insights. The ambition isn’t to replicate platforms like Garmin - it’s to go further. Not just dashboards or wearables, but experiences that genuinely help users understand their health, behaviours, and long‑term wellbeing.

This isn’t about making dashboards look good. It’s about turning complex health data into clear, intuitive, and visually compelling experiences that drive action.

What you’ll be doing

• Owning the design process end‑to‑end — from discovery and problem framing through to final UI and delivery
• Playing a key role in shaping a greenfield product experience across web and mobile
• Defining user journeys where data, insight, and decision‑making sit at the core
• Designing intuitive, scalable UX across complex, data‑heavy products
• Translating health and performance data into clear, structured, and engaging interfaces
• Creating high‑quality UI with strong attention to hierarchy, layout, typography, and visual clarity
• Designing dashboards and data visualisations that make complex information feel simple, useful, and even beautiful
• Working closely with Product, Engineering, and Data teams to shape solutions that are both valuable and buildable
• Prototyping and iterating based on user feedback, testing, and real‑world usage
• Contributing to and evolving design systems to support consistency at scale
• Taking ownership of quality — ensuring what goes live reflects the design intent

What they’re looking for

• Strong capability across both UX thinking (journeys, flows, problem framing) and UI execution (craft, polish, detail)
• Experience working on data‑heavy products (dashboards, analytics platforms, reporting tools)
• A portfolio that demonstrates both product thinking and high‑quality visual design
• Ability to simplify complex problems into clear, usable, and visually intuitive experiences
• Strong interaction design skills, particularly around data exploration, filtering, and navigation
• Confidence working cross‑functionally and influencing product direction
• High proficiency in Figma and modern design tools
• Someone who cares deeply about both usability and visual quality

What makes this interesting

• A true greenfield opportunity to shape a unified digital experience from the ground up
• The chance to help define a product transitioning into a long‑term health and longevity platform
• A role where design directly influences how users understand and act on their health data
• Complex, meaningful problems — not surface‑level UX
• High ownership and real influence across product direction
• A team focused on clarity, impact, and building something genuinely useful, not just aesthetically pleasing
