Leonardo UK operates systems and handles information in highly classified environments. As IT Security Officer for highly classified systems, you will act as the main security point of contact for systems and data at SECRET and above, helping ensure security controls are understood, applied and maintained through life. This role is likely to require regular on-site working across secure Leonardo UK locations, with hybrid working supported where appropriate for duties that do not require access to classified environments.
What you will do as IT Security Officer for highly classified systems:
This aligns to the operating model, which describes the role as taking IT Security Officer responsibilities for highly classified systems and acting as the main security point of contact for systems and data at SECRET and above. The model also describes the need for security architecture support, project delivery governance, security management plans and through-life assurance.
You will bring practical information security experience in secure, regulated or highly controlled environments. You should understand how to apply security requirements in an operational setting and how to support proportionate risk decisions without creating unnecessary friction for delivery teams.
Essential experience and skills:
Experience in information security, cyber security, secure operations, security assurance or a related technical security role.
Experience working with classified, regulated, defence, government or similarly sensitive environments.
Experience reviewing security governance for project delivery, including security requirements, risk records, assurance evidence or readiness criteria.
Understanding of secure system operation, change control, access control, protective monitoring and incident response principles.
Professional security qualification such as CISSP, CISM, Security+, ISO 27001, Certified Cyber Professional or equivalent experience.
This is not an exhaustive list, and we are keen to hear from you even if you might not have experience in all the above. The most important skill is a good attitude and willingness to learn.
