Hybrid

We believe that through collaboration and connection with our colleagues we can achieve great things. Our hybrid working approach allows our people to work both in the office and at home, providing the flexibility and resources you need to succeed in your role. We don't require you to be in on specific days; instead, we ask people to come into the office 2-3 days each week, for at least 8 days per month. You should work with your line manager to understand what their expectations are for you, your specific role and your team.

Because no matter where you live, what your background is, or how you get online – we think everyone deserves the same chance to stay connected, and with VodafoneThree, that future’s being built – today.

We’re creating more than the UK’s best network. We’re helping close the digital divide, empower communities and drive meaningful progress.

We believe that everyone should feel they belong. Whoever you are and whatever your story, there’s space for you here. We’re building a workplace where different perspectives are welcomed, voices are heard, and everyone feels safe to show up as themselves.

You’ll join a team that genuinely cares – about each other, about our customers, and about the future we’re building. From day one, you’ll be welcomed, valued and encouraged to bring your whole self to work.

What you’ll do

You’ll play a key role in shaping how secure, responsible AI is built and delivered across VodafoneThree UK’s technology landscape. Working at the intersection of cyber security and emerging AI innovation, you’ll help ensure that AI-enabled products, platforms, and services are designed with strong security foundations from day one—balancing innovation with risk, compliance, and resilience.

• Define and evolve secure architecture patterns for AI and GenAI systems, covering platforms, APIs, data pipelines, and model environments
• Embed security into the design of AI solutions by identifying and mitigating risks such as data leakage, prompt injection, and model misuse early in the lifecycle
• Lead Secure by Design (SbD) assessments for AI initiatives, ensuring the right level of review and controls based on risk
• Collaborate with Cloud, Data, Networks, and Digital teams to ensure secure configuration of AI infrastructure, including MLOps and compute environments
• Guide programmes and product teams with clear, practical recommendations that balance security, delivery, and innovation
• Drive compliance with regulatory, legal, and internal frameworks (including GDPR, TSA, and Baseline Security Requirements)
• Contribute to AI security standards, policies, and best practices—helping shape how responsible AI is delivered at scale
• Act as a trusted subject matter expert, influencing stakeholders across local and group teams to adopt secure AI practices
• Partner with Cyber Defence, Risk, Audit, and Compliance teams to ensure seamless end-to-end AI risk management
• Support audit readiness by providing evidence, insights, and clear security narratives for AI systems
• Champion the adoption of AI security standards and patterns, improving resilience and reducing risk across the organisation

Who you are

• You bring experience in security architecture within IT, cloud, digital, or network environments
• You have hands-on exposure to AI/ML systems, data platforms, or AI-enabled product design (even if you’re not a developer or data scientist)

• You’re comfortable working across complex, fast-paced environments with multiple stakeholders and competing priorities
• You can review architectures at both high-level and detailed design, offering clear and actionable guidance
• You have a strong grasp of secure design principles, threat modelling, risk management, and zero trust concepts
• You communicate with clarity and empathy, making complex AI security topics easy to understand for non-technical audiences
• You enjoy collaborating, influencing, and building strong partnerships across teams and senior stakeholders
• You bring a forward-thinking mindset and stay curious about evolving AI and cybersecurity trends
• You take a pragmatic, risk-based approach—balancing protection with business needs

It would be great if you also have:

• Experience with GenAI, large language models, or model lifecycle and governance
• Familiarity with cloud-native AI services (AWS, Azure, GCP) and AI security tooling
• Understanding of telecoms security frameworks and regulations
• Relevant security certifications such as CISSP, CCSP, SABSA, or AI/cloud security credentials
