This role sits within giffgaff’s broadband engineering space, with a strong focus on backend development, building the services and platforms that power a seamless, reliable connectivity experience for members. You’ll be responsible for designing, developing and maintaining scalable, fault-tolerant systems that support everything from hardware interactions to customer-facing services, ensuring performance and reliability are at the heart of what you deliver.

Working as part of a cross-functional product engineering team, you’ll collaborate closely with hardware specialists, customer teams and fellow engineers to continuously evolve and improve the platform. While the role is primarily backend-focused, there is the opportunity to contribute to frontend development when needed, using modern technologies to deliver end-to-end solutions. You’ll work with a contemporary tech stack including Java, Spring Boot and AWS on the backend, alongside React and TypeScript on the frontend, all within a culture that champions pair programming, test-driven development and continuous delivery.
