Who are OnBuy?

We have recently been named one of the UK's fastest-growing tech companies in Deloitte's Technology Fast 50 for the third year in a row (as well as 'Fastest-Growing Tech Business in the South West'). 

All achievements we are very proud of, but we don't let that go to our head. We are all laser focused on our mission and understand the huge joint effort ahead of us needed to succeed. 

Working at OnBuy: 

We are a team of driven and motivated people who thrive when working at pace. To succeed at OnBuy you need to take charge and fully own your responsibilities, rolling your sleeves up when needed to 'get it done'. Working at OnBuy you are surrounded by so much opportunity, but you must possess the ability to stay focused and prioritise ruthlessly. Most importantly, you will thrive in an ever-changing environment as we are constantly evolving. 

At OnBuy, you're not just a number or another cog in a machine. We are creating something really special, and you have the opportunity to affect meaningful change and have your voice heard.  

We are a close team, who have the opportunity to learn and grow as OnBuy evolves. We work in a flexible way, meaning we can prioritise our health and relationships, but when we are working, we graft.
