About the role

Key responsibilities & impact

You’ll be using AI to power your workflow of research, prototype, validate, refine and ship.
Research - Get to know users better than anyone. Build tools that pull signal from a wide range of sources – reviews, communities, behavioural data – synthesize it fast and use it to stay laser-focused on the changes that actually help people build a fitness habit and hit their goals.
Prototype – Rapidly turn problems and opportunities from research into lo-fi prototypes. Using the right AI tooling, you'll go from insight to something testable incredibly quickly.
Validate – Engage with users fast and often. Pressure-test assumptions and get feedback on what’s actually landing before spending time polishing.
Refine – Turning a validated idea into something polished requires a strong design eye and it’s probably where AI helps least. Getting here faster and with more confidence will have an enormous impact.
Ship - Work closely with engineering on the handover from prototype to production ready code and stay involved through launch and iteration.

Requirements

What you’ll need

You have exceptionally strong design taste
You've used AI to collapse the time between user insight and validated prototype
You’re keen to push the boundaries between design and engineering, shipping yourself wherever possible and experimenting with Cursor, Claude Code or similar
You care about the details but you don't let them slow you down - fast when it needs to be fast, polished when it needs to be polished
You have strong opinions and aren’t shy advocating for users but you know the goal is to move things forward together, not to win the argument
You’ve delivered in fully remote teams and thrive with collaborative, async work
