Lead Security Architect in SECURITY ARCHITECTURE

Reference: ijoca5rqhsrjoxvkalv0

We are seeking an experienced Lead Security Architect to define and advance secure, resilient technology architectures across a complex and evolving environment. In this senior role, you will establish security architecture principles, standards and patterns that support business strategy while protecting critical systems, data and services. You will work closely with technology, engineering, infrastructure, risk and business stakeholders to ensure security is embedded throughout the design, development and operation of solutions.

Your responsibilities will include leading the creation and review of security architectures, threat models, design decisions and technical roadmaps. You will assess existing and proposed platforms, applications, cloud services and integrations, identifying risks and recommending practical controls. You will provide architectural governance, challenge designs where appropriate, and support the development of policies, standards and reusable security capabilities. The role will also involve advising on identity and access management, network security, data protection, cloud security, application security, encryption, vulnerability management and secure software development practices. You will help translate complex technical risks into clear recommendations for both technical and non-technical audiences.

To succeed, you will have substantial experience in security architecture, cyber security engineering or a closely related discipline, with a strong understanding of enterprise architecture and modern cloud environments. You should be confident working across multiple technology domains and balancing security, usability, cost and delivery considerations. Experience with recognised security frameworks and standards, such as NIST, ISO 27001, SABSA or CIS Controls, is desirable, as is familiarity with regulatory and data protection requirements. Strong communication, stakeholder management, analytical and leadership skills are essential. Relevant professional certifications, such as CISSP, CISM, SABSA or cloud security credentials, would be advantageous. This is an opportunity to shape security strategy, mentor colleagues and influence lasting improvements in organisational resilience.
