Join us at a pivotal moment for BT Business. We are executing a multi-year transformation to restore growth, modernise at scale and unlock new markets beyond connectivity. Our ambition is clear – return to sustainable revenue and EBITDA growth, strengthen our market position, and deliver meaningful shareholder value through disciplined execution and bold reinvention.

We are fundamentally reshaping the business – simplifying our portfolio, digitising our customer experience and building market-leading capability across cyber, AI and managed services, all powered by the UK’s leading fixed and mobile networks. This is a shift from a legacy connectivity provider to a modern, solutions-led, AI-first business that can truly differentiate in a competitive and fast-moving market.

With execution momentum building and a clear path to growth, the opportunity now is to scale what works, accelerate performance and fully realise our potential. This is about delivering against ambitious financial outcomes while transforming how we operate – creating a business that is simpler, faster, more innovative and easier to do business with.

If you want to be part of the team shaping the turnaround of a multi-billion-pound business – and building a stronger, more competitive BT for the future – this is your moment.
