Why are we recruiting for this role?

Supporting the NAO’s strategic objective to improve our digital and data capabilities and enabling innovation, our expanded Information Security team requires a skilled cyber security engineer with broad capabilities, dedicated to delivering new and developing existing cyber security capabilities.

The Cyber Security Engineer will lead on the development of our critical cyber security systems, tools, and processes, maintaining and improving the NAO’s security posture and risk profile in support of our ambition of being an exemplar organisation.

Who are the team?

The role sits within an inclusive, diverse, respectful, and agile team of information security professionals responsible for enabling the business to better understand, identify and manage the threats and risks that could impact the NAO’s ability to deliver on its vision and strategy.

What are the main responsibilities of this role?

The Cyber Security Engineer will lead on the development and optimisation of identity and authentication, secure build and infrastructure security, securing our use of endpoint technologies, and public, private and hybrid cloud technologies, across various SaaS, PaaS, and IaaS services.

The successful candidate will have an excellent knowledge of how to deliver secure-by-design and an understanding of how to develop and enhance these capabilities.

The Cyber Security Engineer will advise on, support, and implement best practice controls within the Microsoft Defender, Azure and Intune suite of security and technology management services.
