Senior Product Designer

FitXR is building a love of movement in everyone. Forget products for people who already enjoy exercise. This is about fitness for the 96% of people who don’t go to the gym and who haven’t already built habits around fitness. Operating at the intersection of spatial and wearable AI, we build experiences that prove exercise can be genuinely fun and for everyone.

While nothing compares to trying it yourself, this trailer gives you a taste.

With > 100,000 users, we have product-market fit and are profitable with an exceptional team of ~35 people and a heavy innovation arc ahead of us.

Right now, our biggest unlock is compressing weeks of research, prototyping and validation into days. You'll be joining us on that journey and helping accelerate it.

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 – synthesise 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.

• 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

• You’re using AI as a thinking partner to refine your ideas but haven’t really overhauled the way you work
  You design purely on instinct or validate only on release with users

• You thrive in well-defined roles with clear handoffs and structured processes
