System Security Architect
We are seeking an experienced System Security Architect to design, develop and maintain secure, resilient technology architectures across a complex IT environment. You will provide expert guidance on security strategy, architecture and engineering, ensuring that systems, applications, networks and cloud services are designed and operated in line with organisational risk appetite, regulatory obligations and industry best practice.
You will work closely with infrastructure, software development, cloud, data and operational teams to embed security throughout the technology lifecycle. Responsibilities will include producing security architecture principles, reference models, patterns and design documentation; reviewing proposed solutions; identifying vulnerabilities and architectural risks; and recommending proportionate controls and remediation plans. You will also contribute to threat modelling, security assessments, technology roadmaps, incident learning and the continuous improvement of security capabilities.
The role will involve translating business and technical requirements into practical security designs covering areas such as identity and access management, encryption, network security, endpoint protection, application security, secure development, monitoring and resilience. You will communicate complex risks clearly to both technical and non-technical stakeholders, supporting informed decision-making and helping teams understand their security responsibilities.
Applicants should have substantial experience in security architecture, systems engineering or a closely related discipline, with a strong understanding of modern infrastructure, cloud platforms, networking and enterprise security controls. Experience applying recognised frameworks and standards, such as NIST, ISO 27001, CIS or SABSA, would be advantageous. Relevant professional certifications, including CISSP, CISM, SABSA or cloud security qualifications, are desirable.
You will be a confident communicator and collaborative problem-solver, able to influence without direct authority and balance security, usability, cost and delivery pressures. Strong analytical skills, sound judgement and the ability to manage competing priorities are essential. This is an opportunity to shape secure technology solutions, strengthen organisational resilience and contribute to a mature, forward-looking security function.
