Who we are
We’re a flexible‑first organisation, because we know people do their best work when they have choice and clarity. To support meaningful collaboration, we ask everyone to spend at least eight days each month connecting in person. That doesn’t just mean time in the office, it could be team meetings, offsites, volunteering days, cross‑functional projects, or away days – anywhere meaningful collaboration happens. What matters is making those moments purposeful, so when we come together, it really counts.
Accessible, inclusive and equitable for all
Virgin Media O2 is an equal opportunities employer and we’re working hard to remove bias and barriers for our people and candidates. We build equity and inclusion into everything we do, from the policies we craft to the relationships we shape. We support and encourage you to be your authentic self throughout your application journey with us.

The other stuff we are looking for
- Experience translating consumer and operational problems into analytics, AI agent, or automation use cases
- Familiarity with conversational AI, LLM fine‑tuning, prompt engineering, and agentic design patterns (call‑centre automation a strong plus)
