Senior Product Designer - App Experience (Independent Contractor)

Own key surfaces of the ZOE app, taking loosely defined gut health problems and exploring widely before shipping high-impact experiences. You'll design native iOS and Android journeys end-to-end, translating complex science into simple, rewarding interfaces. Partner with Product, Engineering and Data to run A/B tests and iterate based on evidence. This senior individual contributor role needs strong creative range, product judgement and craft — someone comfortable with ambiguity who can move quickly when direction is clear. You'll work on habit change, behaviour design and data visualization.
