Frontend Software Engineer in Uxbridge

Here at giffgaff we’re currently on the lookout for talented frontend engineers with a focus on Typescript, Next.js, React and various React ecosystem tools and libraries to join us on a number of exciting projects in 2025. You’ll join a new team creating a greenfield product that will fundamentally change how giffgaff and our members interact with each other and in the telecommunications industry—a brand new area for the business where we’ll focus on self-managed, affordable, and simple ways for people to connect.

We’re looking for frontend engineers with a focus on Typescript, Next.js, React and various React ecosystem tools and libraries. Ideally you are a ‘t‑shaped’ individual, whose expertise runs deep in their chosen area, but are happy to learn and help out in other areas, growing towards a full stack skillset over time.

Who we are

Do you want to join a telecoms company that’s up to good? At giffgaff we do mobile differently. We call out the bad and find a better way. We’re laser‑focused on flexibility, value and mutual good. And we’re so proud to be a certified B Corp. This means we’ve joined a network of more than 1,000 UK companies, who want to make a positive impact on people and the planet. Working at giffgaff is something you could be proud of too.

You’ll get the best of both worlds, the energy and fast pace of giffgaff, plus all the benefits that come with being part of our parent company, Virgin Media O2. Our business model is unique. We work with our members to understand their needs in all areas of the business. We love this highly collaborative approach. Over the past few years our member base has grown steadily, and we’re still going. We’re always looking to acquire new members, and to do that we need the best people in our team.

Our bright and modern gaff is in Uxbridge, in leafy West London. But if commuting isn’t your favourite, most of our roles can be hybrid or work from home, or anywhere in between. If you like coming in, you’ll always find some office buddies. And if you like big occasions, we really bring the office to life monthly for our themed culture days. Plus all our giffgaffers come together at our legendary giffgaff summer, birthday and Christmas celebrations.

The must haves

In order to be considered, you must have the following experience:

• Observability, “you build it you run it” attitude
• Mentoring, good communication, giving and receiving feedback

The other stuff we are looking for

• Event‑Driven Architecture; SOLID principles; microservices; micro frontends
• Experience in telecommunications / connectivity domain

What’s in it for you

Our goal is to celebrate our people, their lives and everything in‑between. We aim to create a culture that empowers everyone to bring the best versions of themselves to work each and every day. We believe the most inclusive and diverse culture makes for a better business and a brighter world. Working at giffgaff means you get a bumper reward package bursting with benefits, and loads of extras you can add if you’d like to. These are designed to support both you and your loved ones, making sure that you’re covered no matter what life throws your way.

We’re all about hybrid working here, so expect to have a base location where you’ll have the right facilities to enable amazing collaboration and quality time with your team, alongside all the right kit to work from home too.

Next steps

If we feel like a place where you can belong, we’d love to learn more about you as a person and your experience to date. Once you’ve submitted an application the next steps of the process, if successful, are likely to include two technical rounds of interview followed by a culture fit check. Please note: Applications will be reviewed, and interviews conducted throughout the duration of this advert, therefore we may bring the closing date forward. We encourage all interested applicants to apply as soon as possible. If you’re offered a job with us, it will be conditional, based on the passing of background checks. All roles require a criminal record check and some roles need a financial probity check. Your recruiter can provide you with more information if needed.
