Engineering Lead - Mobile Engagement

Join our newly formed Mobile Engagement Team at giffgaff and help shape how over 4 million members experience our mobile products every day. This team is all about deepening relationships with existing members - ensuring they feel connected, supported, and genuinely delighted to stay with giffgaff for life. As the Engineering Lead, you'll play a pivotal role in building this vision - driving technical excellence, fostering a culture of innovation, and enabling your team to deliver meaningful, member-first experiences that make a real impact.

This is a unique moment to join us as we redefine our technical strategy, evolving our stack into a modern, microservice-based, event-driven architecture. You'll be hands-on in shaping this transformation - leading a talented group of engineers through best-in-class practices like pair programming, test-driven development, and continuous delivery. If you're a passionate and purpose-driven engineering leader who thrives in a collaborative, product-focused environment and loves empowering teams to achieve great things, this is your chance to help craft the future of mobile engagement at giffgaff.

Key responsibilities

• Lead a team of engineers with a full-stack attitude within a self-organising, cross functional product engineering team using extreme programming practices - notably pair/ensemble programming and test-driven development.
• Be a force-multiplier and change-driver for the team, raising the bar of technical excellence, championing industry best-practices and our engineering principles; driving great behaviours and practices in the team.
• Build, support and maintain automated, fault-tolerant, scalable products and solutions that are 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, tackling problems without giving up, and producing solutions that less-experienced engineers can use, maintain, and learn from.
• Know how to develop and follow a sense of purpose. Be willing to point out, own, and fix things that are broken about our company and in your own career track.
• Work with your other engineering lead colleagues to drive the technical direction and innovation, encouraging collaboration and excellence.
• Client-side: Typescript, Next.js, React and various React ecosystem tools and libraries. Some legacy PHP that we're working very hard to move away from.
• 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.

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.

The must haves

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

• Mentoring, good communication, giving and receiving feedback
• Observability, "you build it you run it" attitude
• Product and iterative development mindset

The other stuff we are looking for

We'd also love you to bring;

• Event-Driven Architecture; SOLID principles; microservices; micro frontends
• Experience in telecommunications / connectivity domain
• A commitment to make ethical and responsible decisions that support giffgaff's impact on people, planet and profit.

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 a call from one of our Talent Acquisition Partners.

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.

Thanks for your patience and for showing an interest in joining the giffgaff family.
