PRINCIPAL Cyber Security architect
As a Principal Security Architect you will be able to work with minimal direction on a range of large and small programmes that deliver IT transformation and new services capabilities. 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 accreditation and certification processes, normally HMG standards (including MOD-specific JSP) alongside ISO27001.
You will have responsibility for interfacing to security design partners across programmes, 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 a programme, and that the designs will be able to adapt as customer requirements, legislation and accreditation standards change over a programme lifespan.
Within a programme, the role will primarily be responsible to a solution architect for developing and delivering the relevant elements of a solution, whilst understanding the whole initiative. You will be required to work in both delivery and proposal environments. You may be required to work on multiple programmes at the same time and these may include bids, implementation of new systems and transformation of existing systems.
You will have a complete understanding of cyber risk and treatment approaches. Based on a strong ability to communicate risk and its proportionate management, you will know how this issue is addressed both in traditional ‘off-cloud’ highly sensitive platforms, and naturally in cloud technologies. You will be experienced and accomplished in meeting the challenges associated with accrediting systems in public and private cloud environments.
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.
The Leidos client base includes a number of national government departments and arms-length bodies, local authorities and providers of critical national infrastructure. We take our security obligations very seriously and will ensure there is a strong security component to all our proposals, and will be able to demonstrate a sound security operation is enabled by the solution we design for our clients. You will be required to hold security clearance under National Security Vetting and Police 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.
