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 doOwn major surfaces end-to-end; research, flow, interface, prototype, spec and QA of what ships — across both product and growthTurn clinical blood results into something a non-clinician can understand and act on alone, on their phoneDesign the day-to-day experience across the four pillars (Eat, Move, Sleep, Relax), turning results into a plan members actually followDesign for personalisation, so members with different biology get genuinely different products without the system falling apartOwn the acquisition and activation experience alongside product and growth, so the first impression matches the quality of the productBuild and hold the design system as the team grows, rather than retrofitting one laterBalance long-term product direction with near-term shipping; setting design direction for the next few quarters, not just the next sprintWork directly with product and engineering, and make the case for your decisions directly to leadership and clinical stakeholdersWho you areAround 4+ years of product design experience, with consumer products you've shippedHave a portfolio of shipped consumer work you can talk about honestly — what the problem was, what you killed, what you'd change nowStrong visual and interaction craft that holds up under close inspection, not just from a distanceFluent with dense information (ranges, trends, states) and skilled at making it feel calm rather than clinicalMobile-first instincts, with real prototyping ability that tests assumptions, not just presents themComfortable owning outcomes rather than screens, and being measured on themExercise good judgement in ambiguity — most decisions here don't have an obviously right answerConfident, responsible user of AI tools — a force multiplier where they help, set aside where they don't
