Founding Product Designer

'Normal' health is no longer good enough. Normal is code for tired, stressed, barely functioning and slowly declining, and calling that a life. We think everyone has a right to better than that.

Stride is turning tracking your entire internal biology into a lifestyle, with a next generation preventative health membership. Every member builds a multi-omic health profile covering DNA, microbiome, blood biomarkers, epigenetics and oral health. That's over 500 biomarkers, tested at least twice a year, so we can see direction of travel and not just a single point in time.

Then we turn it into what to actually do: what to eat, how to train, what to supplement, what to watch, with a coach, dietitian or physiologist alongside you.

Imagine an elite longevity concierge, at an everyday price, with no stuffy clinics to attend!

This is yours to own. Most health products hand people a page of numbers and leave them to work out what it means. Your job is to make sure none of Stride's science gets lost between the lab and the person trying to live better because of it.

You’ll own product design for the member experience end to end: the app and web surfaces where someone sees their results, understands what changed, and knows exactly what to do next. You’ll work closely with the Head of Product (Olympic athlete, exercise physiologist, ex-DNAfit, FIFA and Prenetics), our CTO and the wider product and engineering team. You’ll take problems from rough idea to shipped, polished experience.

Your biggest challenge will be our flagship biological age platform. It's a longitudinal, multi-omic view of how someone's rate of ageing changes over time. It's backed by both an Innovate UK grant and a multi-million-pound Innovation Loan, and there's no obvious template to copy.

• Design end to end across onboarding, results, protocols, coaching and community

• Turn dense biomarker and trend data into visualisations that are easy to understand at a glance

• Run lightweight research and testing to validate decisions, not just rely on instinct

• Build and evolve a design system that keeps the product coherent as it grows

• Design how members see their biological age over time: trends, comparisons, and the moments that make the data feel real

• Turn a genuinely novel scoring model into an interface nobody has quite built before

• Work with our scientific team to keep it rigorous and evidence-based while you simplify it

• Partner with product and engineering from the earliest framing of a problem, not just at handoff

• Work with our clinical team so design never compromises accuracy or trust

• Collaborate with marketing and brand so product and brand reinforce each other

• Use AI natively for research synthesis, rapid prototyping and exploring more directions, faster

• Bring judgement on where AI speeds up craft and where human taste still has to lead

• Members understand their results and know what to do next

• Design quality and consistency as the product scales

• Speed from problem to shipped, well‑considered solution

• Measurable impact on engagement, retention and trust

• A few years designing complex digital products, ideally consumer-facing, where you owned problems end to end

• Real skill at simplifying complexity: dense data or complicated processes made intuitive

• Strong craft across the full process, from research and flows to production‑ready design

• Fluency with AI tooling as a genuine part of your process, not a novelty

• Comfort working closely with engineering, and a…
