Flexible & Hybrid Working: We said you'll get freedom to work in a way that is best for you, and that extends to being in the office – or not.

Work better from home? No worries. Prefer the office? Come on down. We have 2 mandatory Townhall days; Spring and Autumn, where the whole business gets together. When you visit the office you won’t just find rows and rows of desks. No, you’ll find our colleagues meeting on the walking pads, having planning sessions over a game of tennis table or grabbing a bean bag in our ‘Quality’ collaborative space - that’s right we live our values so much, we named our meeting spaces after them.

You can also shape work around your life at Airbox Systems; most colleagues work our core hours of 9am-5pm with others flexibly between 7am-7pm. Whether you're fitting in a spin class or the school run, you'll have the flexibility for whatever matters most. All we ask in return is that you produce great work, but when you’re working with passionate people, that part comes naturally.
