NOWATCH is a beautiful piece of wearable jewellery capable of measuring a range of different vital signs and analyses. Being a screen-less device, the product comes with an app to monitor data and foster habit change. Whilst most other wearable focus on optimisation and performance for fitness, NOWATCH focuses on helping people restore balance in daily life.

We are looking for a Senior iOS Developer to join our team and play a crucial role in building and enhancing our iOS app, ensuring it delivers a seamless and intuitive user experience. If you’re passionate about creating innovative health-focused applications, working with sensor-based data, and pushing the limits of what iOS can do, we’d love to hear from you!

As NOWATCH evolves, so does the fluid nature of your role. Remember, while this description outlines core responsibilities, our dynamic environment may require adaptability and ingenuity. We value you not just for your skills, but also for the human touch you bring, infusing our code with dedication, passion, and the essence of NOWATCH.
