As a result of some exciting programme wins, we currently have a permanent vacancy for a Cyber Security Architect to support the development and transition into live of a new IT application and infrastructure solution providing support to a critical operational end user. Leidos is seeking an enthusiastic protective security specialist to lead the implementation and assurance of security within a key defence project.

The incumbent will possess specialist skills in all areas of protective and information security and have demonstrable experience of applying security frameworks such as Government Functional Standard 007.

They will be joining a team of highly skilled and highly motivated individuals who are working on one of the UKs leading programmes.

Required Skills:

As a Cyber Security Architect, you will be able to work with minimal direction on a specific MOD programme. You will ensure that the solution security design meets the customer functional and non-functional security requirements and provides the necessary assurance to our client, highly likely to be backed up by rigorous assurance and certification processes, normally HMG standards (including MOD-specific JSP), NCSC and NIST 800 standards.

You will have responsibility for interfacing to security design partners across the programme, both customer and supplier representatives, and colleagues within our engineering, service, and business development teams. You will ensure that Leidos can establish and maintain an effective and efficient security architecture for the programme, and that the designs will be able to adapt as customer requirements, legislation and assurance standards change over the programme lifespan.

You will be required to develop high- and low-level security architecture designs for systems intended for secure/sensitive environments, with appropriate security based on detailed risk analysis. SABSA qualifications and experience would be desirable. You will be required to hold security clearance under National Security Vetting processes.

You may need to work on customer locations or one of our secure development locations, or a mix of both, as well as an element of working from home.
