We’re a sports technology company born out of London making a huge impact on the world of skiing. Built in consultation with Olympians, Carv gives casual skiers access to the feedback and knowledge that only elite skiers have had access to so far. With an extremely thin and intelligent insert, Carv measures your motion and pressure distribution then relays actionable feedback through the user’s earphones in real-time.

Our candidate is someone who is:

- A skier with a love of the great outdoors. - Experienced (ideally 1+ yr) in Swift and 2+ years in iOS with an app or 2 to show for it. - Willing to learn with a strong foundation to build upon. - Willing to get their hands dirty and communicate ideas effectively with an attention to detail - A person who finds a fast-moving, unpredictable and constantly evolving work environment to be buckets of fun.
