work, define our culture and we encourage everyone to bring their whole selves to the gaff. That's why we believe in creating an equitable, fairer, more inclusive business that champions different ideas and perspectives.

part of the country isn't warming your cockles - please don't be put off from applying for this role. The world has changed - particularly when it comes to ways of working. Most of our roles can be on a work from home basis if needed, but we'll ferry you in a few times a year from wherever you are in the UK for team or company days, or our famous giffgaff summer and Christmas celebrations. Who we are : giffgaff is a little different to your 'normal' telecoms company. We're a mobile brand owned by Virgin Media O2 but run by our members (what we call our valued customers) and we've been awarded Uswitch Network of year for 6 years out of 7! Sounds interesting so far? There's more. The word giffgaff is an ancient Scottish word for "mutual giving". Since we were founded upon the principle of putting community first, it's always been our aim to do right by the planet and the people that live on it. We started wanting to change the mobile industry, and we did - offering value, flexibility and mutuality - but we aren't done yet . As we've grown over the years, we've grown our vision too. We believe it's our responsibility to make sure that: * Keeping people connected doesn't damage the planet * Everyone can be connected, so everyone gets the same opportunities * The connections we make online improve our lives Our business model is unique. We take a highly collaborative approach to any decision we make - working with our members (who are rewarded for helping) across all areas of the business. Our vibrant community, online platform and immense value proposition are key to our success. We're both proud and humbled to say that over the past few years our member base has grown, but our job is far from done. We're always looking to acquire new members - but to do that we need the best people to help and that's why we're hiring!
