Lead Product Designer

Senior Product Designer

At Thriva, we're on a mission to close the gap between lifespan and healthspan. While people are living longer, they're also spending more years in poor health. We help people live better now, and for longer, with proactive at‑home blood testing, connected wearables, doctor‑reviewed results, and personalised actions backed by evidence.

We're building a first‑of‑its‑kind proactive health app, combining deep clinical insight with human‑centred design, conversational coaching, and increasingly sophisticated data insight. As Lead Product Designer, you will bring craft from unpacking the shape of the problem to the pixels in production, and set the bar for design quality across the company. We are looking for a designer who sees design as a creative problem solving exercise, who knows how to explore a solution space and then select and refine creative UX solutions in production in partnership with product and engineering.

This might mean inventing novel patterns when they're warranted, and it will always mean designing experiences that meet people where they actually are in their health journey. If you're the kind of designer who is energised rather than daunted by tackling messy human problems head on, this is for you.

This is a hands‑on role across an exciting product portfolio. You'll be the senior design voice in a lean, fast‑moving team: setting direction, holding the quality bar, and doing the craft yourself. If that combination of strategic ownership and getting‑your‑hands‑dirty excites you, you'll thrive here.

We're a purposefully small team that moves fast. Our CTO Founder writes code, our Product Director runs user interviews, and our Product Managers prototype in code. Designers and engineers work shoulder to shoulder, increasingly using the latest AI tools to accelerate both the design and the build of first‑class experiences. We're looking for someone excited by that way of working and ready to help us define how design operates as we grow our impact and pace in a fast moving market.

• Set and hold the design vision across the entire Thriva journey — physical and digital — from the at‑home sampling experience through to the app, results, insights, and coaching
• Carry Thriva's design‑led heritage forward and raise the standard of design thinking across the team
• Constantly connect the dots across touchpoints so the product feels like one considered, coherent whole rather than a set of features

• Shape our ways of working at lead level: how designers and engineers collaborate day to day, and how we keep quality high while moving fast with prototyping and AI tooling
• Own the review and approval of new additions to the design system, keeping it consistent, scalable, and a genuine accelerator for the team
• Establish the rituals, standards, and guardrails that let a lean team ship first‑class work quickly with the right cross‑functional input

• Act as the guardian of a single, coherent experience across every touchpoint — visually, in interaction, and in tone
• Ensure clinical insight, data, and content come together in interfaces that feel calm, trustworthy, and unmistakably Thriva

• Represent design in product and whole‑team conversations, and advocate for both the user and the craft, supporting an understanding of design‑led thinking as the route to world class product experiences
• Bring others along with your thinking, mentor and raise the level of those around you, and influence product strategy with a strong design perspective

• Solve hard product problems with creativity and rigour
• Explore the solution space for ambiguous, novel problems and create patterns that genuinely meet users where they are
• Design for real behaviour change — building experiences that encourage healthy action, habit‑building, and reflection in the real world
• Balance engagement with restraint, avoiding dark patterns or addictive mechanics in favour of meaningful, lasting impact over months and years
