The Opportunity

Do Health is Voy's next chapter: a mobile-first preventative health product co-founded by Dr Rangan Chatterjee, built as an independent startup inside Voy, one of the UK's fastest-growing digital health companies. Unlike Voy's existing work in men's health, metabolic health, menopause, hormonal health, TRT and dermatology, Do Health is built not to treat illness, but to prevent it - testing members' blood regularly and turning results into a personalised programme across four pillars: Eat, Move, Sleep, Relax.

You'll join as the senior design voice on a small team, with no layer of management between you and the work. What you ship in month one is what members get — you'll own major surfaces end-to-end, working directly with product and engineering, with no tickets thrown over walls.

What you'll do

• Own major surfaces end-to-end; research, flow, interface, prototype, spec and QA of what ships — across both product and growth

• Turn clinical blood results into something a non-clinician can understand and act on alone, on their phone

• Design the day-to-day experience across the four pillars (Eat, Move, Sleep, Relax), turning results into a plan members actually follow

• Design for personalisation, so members with different biology get genuinely different products without the system falling apart

• Own the acquisition and activation experience alongside product and growth, so the first impression matches the quality of the product

• Build and hold the design system as the team grows, rather than retrofitting one later

• Balance long-term product direction with near-term shipping; setting design direction for the next few quarters, not just the next sprint

• Work directly with product and engineering, and make the case for your decisions directly to leadership and clinical stakeholders

Who you are

• Around 4+ years of product design experience, with consumer products you've shipped

• Have a portfolio of shipped consumer work you can talk about honestly — what the problem was, what you killed, what you'd change now

• Strong visual and interaction craft that holds up under close inspection, not just from a distance

• Fluent with dense information (ranges, trends, states) and skilled at making it feel calm rather than clinical

• Mobile-first instincts, with real prototyping ability that tests assumptions, not just presents them

• Comfortable owning outcomes rather than screens, and being measured on them

• Exercise good judgement in ambiguity — most decisions here don't have an obviously right answer

• Confident, responsible user of AI tools — a force multiplier where they help, set aside where they don't
