Staff Product Designer - Do Health

Do Health is a mobile-first preventative health product, co-founded by Dr Rangan Chatterjee and built as an independent startup inside Voy - one of the UK's fastest-growing digital health companies (more than 100% YoY growth every year since inception, ~750k active customers across the UK, Germany, Brazil and India), already working across metabolic health, menopause, hormonal health, TRT and dermatology. Do Health is Voy's next chapter: the first product built not to treat illness, but to prevent it. We test people's blood regularly, track how it changes over time, and turn results into a personalised programme across four pillars - Eat, Move, Sleep, Relax - that helps someone make small changes they can actually keep.

The Opportunity

Do Health is a mobile-first preventative health product, co-founded by Dr Rangan Chatterjee and built as an independent startup inside Voy, one of the UK’s fastest-growing digital health companies. Voy has over 1 million members across the UK, Germany and Brazil, and Do Health is its next chapter: the first product built not to treat illness, but to prevent it.

We test people’s blood regularly, track how it changes over time and turn results into a personalised programme across four pillars (Eat, Move, Sleep, Relax) that helps someone make small changes they can actually keep. Almost everything a member experiences is design, from a result they have to understand to a habit they have to keep. You’ll join as a senior design voice with the scope to set design direction and the craft bar for your area, working alongside product and engineering leadership as a strategic partner. This is a hands-on role, not a management one.

What you’ll do

• Set the design direction for your area, winning buy-in across product, engineering, clinical and leadership
• Own the hardest problems end to end, from research through to shipped and measured
• Turn clinical results into something members understand and act on
• Set and hold the craft bar, raising the team’s work through critique and pairing
• Own the direction of the design system as personalisation grows
• Shape the roadmap, not just the screens, by identifying the problems worth solving and making the case for investment
• Lead the research agenda and be the clearest voice in the company on what members need
• Design across the whole journey, from first ad and checkout to first result and the habits that follow

Who you are 

• Around 5+ years of product design experience at Senior level or above, ideally with depth in design systems, growth and funnels, data-heavy products or regulated products
• A portfolio of shipped consumer products you can talk about honestly: the problem, what you killed, what you’d change now and how it performed
• Craft that sets the bar for others, with work that holds up at 100% and at arm’s length
• Evidence of setting design direction beyond your own features, and of changing what a team or company decided to build
• Experience extending or leading a design system and keeping it coherent under pace
• Fluency with dense information (ranges, trends, states) and a talent for making it feel calm rather than clinical
• Comfort with data: you design the measurement alongside the design, read experiment results and know their limits
• The ability to explain your work simply and make the case to leadership and clinical stakeholders directly
