The AI Security Architect will lead the design and implementation of robust security architectures, standards, and governance frameworks for Artificial Intelligence (AI), Generative AI (GenAI), AI-powered applications, agents, copilots, and enterprise environments.
This role requires a deep understanding of AI security, AI governance, cloud-native security, application security, data security, and enterprise security technologies. You will work closely with product teams, AI engineering teams, developers, security engineers, DevSecOps, legal, risk, and operations teams to ensure security is embedded throughout the application lifecycle, from solution design and vendor selection to deployment, operation, and ongoing monitoring. The role will define secure AI architecture patterns, provide security oversight for AI initiatives, and enable responsible AI adoption aligned with organisational policies and industry frameworks.
Reporting to the Enterprise Security Architect and collaborating with stakeholders, such as the Head of Cyber Security, BISOs and Solutions Architects, you will assist in promoting a harmonised security architecture via standards, patterns, and tooling.

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.
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.
