About the Role
Virgin Media O2 is transforming how it uses data to run the business. Across pricing, network operations, customer care, and personalisation, we are building the products and services that help the company make better decisions, faster.
As a Staff Software Engineer, you will be at the centre of that work. You’ll design and build backend systems that handle real scale and real consequences: services that shape how we invest in our network, how we retain and grow our customer base, and how we support millions of customers when things go wrong. Your code will run in production, and your judgment will shape the technical direction of the teams around you.
This is a role for someone who wants to solve hard problems with good engineering. You’ll work across team boundaries, influence architectural decisions, and set the standard for how we build software. You’ll do this primarily by writing code, not by stepping away from it.
Who We Are
At Virgin Media O2 we’re going All In, to remove bias and barriers for our people and our candidates. We’re working hard to achieve bold ambitions, to help us better represent the diverse communities we serve across the UK. As an equal opportunities employer, we support and encourage you, to be your authentic self throughout your application journey.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
The Must Haves
- Expert-level proficiency in Python, with a track record of building production systems that are testable, maintainable, and built to last.
- Strong architectural instincts. You design systems that balance scalability, reliability, and cost, and you explain the trade-offs clearly to both engineers and stakeholders.
- Hands-on experience with cloud environments. Our stack includes BigQuery, Cloud Run, Spanner, and Vertex. You should be comfortable making infrastructure decisions, not just working within what exists.
- Familiarity with infrastructure-as-code (Terraform), and modern CI/CD practices.
- End-to-end ownership of services: from design through to production operation, monitoring, and incident response. You build it, you run it.
- The ability to see past the immediate problem. You identify systemic issues, propose long-term strategies, and ensure the platform can support what comes next.
- A track record of raising the bar beyond your own team, through code review, architectural guidance, or establishing practices that others choose to adopt.
- Clear communication across audiences. You can translate technical complexity for non-technical stakeholders and bring clarity to ambiguous problems for the engineers around you.
- A natural instinct for developing the people around you, through pairing, constructive feedback, and leading by example.

- Knowledge of Vertex AI or GCP's broader AI/ML services.
- Experience working in regulated or large-scale telecoms environments.
What's in it for You
We know that benefits mean so much more than the ‘stuff’ we can give you, so we offer a wide range of support, rewards, and tools, all focused on helping you to prioritise what really matters.
All work and no play just isn’t our style! We’re constantly evolving our approach to enable you to find a great work life balance.
Next Steps
