Senior iOS Developer

About SpareRoom

Since launching in 2004, SpareRoom has helped over 17 million people around the world find homes to share — and great people to share them with. We believe living with the right people beats living alone, so our mission is simple: to create happier flatshares. We're independently owned by our founder and directors, which means we make decisions that put our users first. We work with humble, motivated people who bring positive energy and love turning great ideas into reality.

As part of SpareRoom's Apps Team, you'll work on products that are used by millions of people across the UK & US, have been featured by Apple — including as App of the Day — and consistently rank alongside the biggest names on the App Store. With over 100,000 user reviews and a 4.6-star rating, our apps are genuinely loved by our community.
