Job description

Help protect the systems and services that keep Virgin Media O₂ connected. As a Security Support Engineer, you’ll provide engineering and operational support for a broad range of security platforms, helping to keep our security tooling available, reliable and effective. You’ll configure and maintain technical security policies, support monitoring services used by our Security Operations Centre, and contribute to the automation and integration of security systems. From troubleshooting incidents and deploying new rules to supporting upgrades, audits and continuous improvement, you’ll collaborate with internal teams and technology vendors to solve problems and strengthen our security capabilities. Who we are

At Virgin Media O₂, we connect people to the moments that matter most. Virgin Media leads the UK for broadband reliability, speed and overall performance, while O₂ keeps people connected on the move with award‑winning coverage.

We’re also proud to be named one of the Financial Times Top 500 Best Employers for 2026, based on one of the UK’s largest employee satisfaction surveys.

Join us and you’ll be part of a team that stays curious, positive and focused on making life easier for our customers and each other. We’re investing in the future of connectivity, from expanding next‑generation 5G to exploring satellite‑supported solutions that help reach rural communities and hard-to-connect places.

You’ll work with people who back good ideas and give you plenty of room to grow. So if you’re looking for a place where you can feel supported, trusted and genuinely valued, you’ll feel right at home here.

Our ways of working

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 a month connecting with each other 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. What matters is making those moments count – so when we come together, it benefits everyone.

Accessible, inclusive and equitable for all

We believe a better tomorrow starts with the choices we make today. That means moving the dial on diversity, building equity into everything we do and putting inclusion at the heart of our business.

Virgin Media O₂ is an equal opportunities employer and we work hard to remove bias and barriers. We want every person who joins us – and everyone thinking about joining us – to feel seen, heard and supported.

When you work with us, you’ll have access to our award‑winning employee network groups. These communities bring people together, champion allyship and create uplifting spaces where you can learn, share and feel part of something bigger. They play a big role in helping people feel connected from day one.

In order to be considered for this role you must have the following experience;

Strong understanding of Windows Server and Linux operating systems, particularly Red Hat
Experience using network troubleshooting tools and methods to diagnose and resolve issues
Scripting or coding experience in at least one language, such as Bash, Python or PowerShell

CompTIA Security+ certification

The other stuff we are looking for

We would also like you to bring;

Cloud foundation or associate‑level training, such as AWS Associate or Google Cloud Associate
Hands‑on exposure to endpoint or perimeter security controls
Experience supporting policy‑driven security technologies
An interest in automation, integration and continuous improvement
A commitment to ongoing professional development and further security certifications

What's in it for you

We know life isn’t just about work, so our benefits are built to support you in the moments that matter. You’ll get Bupa healthcare, wellbeing support, life cover, a pension and generous holiday -plus your birthday off.

And there’s more. Enjoy some extra perks on us, with optional electric vehicle lease and Cycle2Work schemes, dental insurance, neurodiversity assessments, and brilliant discounts on broadband, TV and mobile. You’ll even get access to the Virgin Family platform and the O₂ Priority app, with exclusive rewards, experiences and chances to attend events at The O₂ and beyond.
