You'll join a new team creating a greenfield product that will fundamentally change how giffgaff and our members (that’s what we call our lovely customers) 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 strive for an outstanding user member experience in all areas of giffgaff, so we are looking for a passionate and enthusiastic software engineer who cares about the quality of their work and how the software and services they create will positively impact members. We’re constantly looking for ways to improve and evolve how we solve problems, driven by new, modern practices and challenging the status quo.

You will work in focused and dedicated, cross-functional teams with like-minded people to ensure this product is successful and sustainable. We work with many teams at giffgaff, including various partners and associates we rely on, to ensure we're active and engaged with our engineering community, improving our ways of working and maintaining a high standard and quality of products we create.

Our tech stack:
• Server-side: Java 17, Maven, Spring Boot, JUnit.
• Client-Side: Typescript, Next.js, React and various React ecosystem tools and libraries
• Infrastructure: AWS, Kubernetes, Terraform, Kafka, DynamoDB, PostgreSQL, Redis, ElasticSearch, Kibana, Grafana, and Prometheus.

However, you should be comfortable using a variety of frameworks, languages, and tools and be happy to learn new skills when the need arises.

Key responsibilities:
• Work with a full-stack attitude within a self-organising, cross-functional product engineering team, using extreme programming practices, notably pair programming and test-driven development.
• Build, support and maintain automated, fault-tolerant, scalable products and solutions continuously delivered into our production environment.
• Leverage your experience and skills to assist your team in establishing the best architecture for your products and services.
• Be technically curious, proactive and able to produce solutions your colleagues can use, maintain, and learn from.
• Know how to develop and follow a sense of purpose. Identify improvements in the software that you use and build. Accept feedback and adapt to your team and the company's current priorities.

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 (our customers) 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
• Test Driven Development, Pair Programming, Clean Code & Refactoring, System Design
• Observability, “you build it you run it” attitude
• Product mindset
• Mentoring, good communication, giving and receiving feedback

The other stuff we are looking fo
• Event-Driven Architecture; SOLID principles; microservices; micro frontends
• Experience in telecommunications / connectivity domain

What's in it for you

At giffgaff we want to challenge the old way of doing things. People, and the way they 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. We may be sort-of-small but we're big on that caring, sharing thing & strive to create a supportive culture.

As a lean organisation, our team is built of a diverse, spirited range of people who are multi-skilled, highly motivated and flexible.

In return for your outstanding efforts, you'll be rewarded with a competitive salary and excellent benefits. We believe that hard work should be supported and recognised.

If this sounds like you, we’d love to hear from you.
