What you’ll be doing

The Chief Security Office (CSO) plays a critical role in safeguarding the Group against an increasingly complex threat landscape while supporting its vision of helping Britain prosper. As AI reshapes both opportunity and risk, we are strengthening our capability to secure the Group’s rapidly expanding AI ecosystem. We are looking for an experienced AI Security Engineering Lead to design and deliver the secure engineering patterns, controls, and tooling that protect our AI and machine learning systems. This is a hands-on technical leadership role, where you will take ownership of complex problem spaces and lead through engineering expertise. You will work directly on code, automation, and platform design, while influencing direction and embedding best practice across AI security engineering in collaboration with senior technical customers and cross-functional teams. The role is suited to a senior engineer with deep expertise in AI/ML security, modern software engineering, and secure-by-design approaches. You will champion secure architectures, embed DevSecOps practices, and help elevate engineering capability as the organisation adopts generative AI, agentic systems, and automation at scale.

What we’re looking for

• Experience operating as a senior security engineer and leading engineering initiatives in a DevSecOps environment.
• Strong expertise securing AI and ML systems at scale, including model lifecycle security, data pipelines, and secure deployment.
• Strong hands-on experience with machine learning stacks, such as PyTorch, TensorFlow, MLflow, Kubeflow, or equivalent managed platforms (e.g. Vertex AI, Azure ML).
• Solid understanding of cloud-native and containerised architectures, including Kubernetes and serverless technologies.
• Experience operating in complex hybrid environments, spanning public cloud, private cloud and on-premise platforms.
• Experience building automation and engineering tooling using Python, Go, or similar languages.
• Certifications such as CISSP, CCSP, or cloud security accreditations are appreciated but not required.

Training, certifications, and learning pathways across AI, Cloud, Security Engineering, and Architecture.
• This is a place for you… Our ambition is to be the leading UK business for diversity, equity and inclusion, supporting our customers, colleagues and communities. We are committed to creating an environment in which everyone can thrive, learn and develop. We were one of the first major organisations to set goals on diversity in senior roles, create a menopause health package, and launch a dedicated Working with Cancer initiative. We offer reasonable workplace adjustments for colleagues with disabilities, including flexibility in office attendance, location and working patterns. As a Disability Confident Leader, we guarantee interviews for a fair and proportionate number of applicants who meet the minimum criteria for the role and have a disability, long-term health or neuro-divergent condition, through the Disability Confident Scheme.
