Job description

The role

In this role, the focus will be on researching how to design secure architectures and systems around AI, rather than building or securing models directly. Close collaboration is expected with teams researching core GenAI security, as well as those examining broader socio-technical considerations and supporting capabilities.

Assessing how AI technologies can be integrated into both existing and emerging architectural models is a key aspect of the role. This includes working with cloud platforms such as AWS, Azure, Google and GCP, as well as areas like identity and access management, AI agents, and hybrid cloud environments. Responsibilities also include contributing to the development and evaluation of secure frameworks, tools and architectures, and supporting the development of NCSC guidance on the safe adoption of GenAI.

This work provides an opportunity to further develop expertise as a security architect while contributing to a wider range of AI and broader architectural initiatives.
