Senior Software Engineer

Date: 24-Jul-2021

Location: UXBRIDGE, GB

Company: Telefonica S.A.

giffgaff is a little different to your `normal` telecoms company. It’s a mobile business run by its members. Sounds interesting? It is.

 

We may be a small company, but we like to think big and take a different approach to telecommunications. At the heart of it, we believe in mutuality and simplicity. A better way to do mobile. We'd rather our members stay with us because they want to, not because there's a nasty contract forcing them to. It's why we work our socks off every day to keep them and guess what? It works. We're uSwitch Network of the Year 2021.

 

giffgaff is a fast growing mobile network. Our business model is unique - we take a highly collaborative approach with our members who help (and are rewarded for helping) across all areas of the business.
