Staff Product Designer - Do Health

Voy is a healthcare platform led by clinicians. We support people managing long-term health conditions with treatment plans backed by real evidence.

Founded in 2018, we started as MANUAL, focusing on hair loss, weight loss and men’s health. As we grew, we realised we could help more people. In 2025, we became Voy and expanded into more areas of health, including female hair loss, testosterone, menopause, dermatology and diagnostics with Do Health.

Today, Voy has around 750,000 active customers and has treated more than 2 million people since we began. We work across the UK, Germany, Brazil and India to make a new future of healthcare a reality. We’re approaching $1bn in ARR and have grown more than 100% year on year, every year since inception. At Voy, we let the evidence do the talking. In a published study of over 100,000 people, those who reached 12 months in the Voy programme and stayed engaged lost up to 24% of their body weight.

Our vision is simple: to make 100 years of healthy living within reach for everybody. Our mission is to bring quality care to everyone, at scale.

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
