Security Support Engineer

This job is with Virgin Media O₂, an inclusive employer and a member of myGwork – the largest global platform for the LGBTQ+ business community.

We're hiring not one, but two Security Support Engineers to join our Security Engineering team. This is a hands‑on role at the heart of how we keep Virgin Media O2 secure, supporting the tools and platforms that protect our customers, our colleagues and our networks every single day. You'll be working across a wide range of security technologies, from SIEM and monitoring tools through to endpoint, identity, cloud and perimeter controls. No two days look the same. One minute you might be tuning policies or deploying new configurations, the next you could be automating integrations, supporting an investigation or working with vendors and internal teams to keep our security tooling running smoothly and improving all the time.

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.

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.

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.

The must haves:

• Strong working knowledge of Windows Server and Linux operating systems, with experience in Red Hat environments.
• Proven ability to use network troubleshooting tools and techniques to diagnose issues and identify effective solutions.
• Hands on experience with scripting or coding in at least one language such as Bash, Python or PowerShell.
• Demonstrated problem‑solving mindset, with the ability to break down complex technical issues and communicate them clearly to a range of stakeholders.
• Experience working with at least one Security Incident and Event Management platform, such as Splunk, ArcSight, Azure Sentinel or Google Chronicle.
• Practical understanding of policy driven security technologies, with hands on exposure to endpoint and or perimeter security controls.
• CompTIA Security+ certification (or equivalent) is required.

The other stuff we are looking for:

• A naturally inquisitive approach, with the curiosity to dig into issues, ask the right questions and get to the root cause rather than settling for surface answers.
• Strong attention to detail, with the ability to work methodically, follow processes accurately and spot inconsistencies while balancing pace and quality.

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.

Next steps:

If this feels like a place where you can belong, we'd love to see what you can do. Once you apply, the next steps might include a call with a recruiter, a video interview, an interview with the hiring manager and a task or assessment. We'll also ask about any adjustments you might need, and we'll do our best to make them happen. We review applications and interview throughout the advert window, so it's worth applying sooner rather than later. If you're offered the role, the offer will be subject to background checks, including a criminal record check and, for some roles, a financial background check.
