We’re looking for an Android or iOS developer to join our existing engineering team of two web developers and two mobile engineers. 
Our flagship apps – Zombies, Run! and The Walk – combine innovative real-world interaction and gameplay with captivating stories and design. In short, we make exercising fun. We want to find someone who can help us maintain and improve our existing apps and develop new experiences that are just as revolutionary and innovative.
As a Senior Mobile developer at Six to Start, you will be primarily responsible for maintaining our mobile apps including Zombies, Run! and The Walk, with over 10 million downloads. You’ll work with a fully remote development team and be able to make an impact straight away.
This is a fully-remote position open to all locations, but you will need to overlap with at least 3 hours of 9am-5pm UK time (e.g. 9am to 12pm, or 2-5pm, etc.)
Our pay range is £68,000 to £75,000 dependent on experience.
