Lead Security Architect – AI & Data
We are seeking a Lead Security Architect – AI & Data to define and deliver secure, resilient and scalable architecture across data platforms, artificial intelligence solutions and emerging technologies. You will provide technical leadership throughout the design and delivery lifecycle, ensuring security is embedded from the outset and aligned with business objectives, regulatory obligations and recognised industry standards. The role will involve working with engineering, data, technology, risk and delivery teams to establish practical security controls without limiting innovation.
You will develop and maintain security architecture principles, reference models, patterns and roadmaps covering cloud services, data platforms, machine learning, generative AI, APIs, applications and infrastructure. Key responsibilities include identifying and managing cyber, privacy and information risks; conducting threat modelling and security assessments; defining appropriate controls for data classification, identity and access management, encryption, secrets management, monitoring and resilience; and reviewing proposed designs, suppliers and technical solutions. You will also support the development of AI governance, model security and responsible data-use practices, while contributing to incident response, assurance activities, audits and continuous improvement.
The successful candidate will have substantial experience in security architecture, with a strong background in data security, cloud technologies and AI or machine learning environments. You will be confident translating complex risks into clear recommendations for both technical and non-technical audiences and influencing decisions at senior level. Experience with enterprise architecture frameworks, secure development practices, privacy principles, risk management and relevant regulations is highly desirable. Professional security or architecture certifications, such as CISSP, CISM, SABSA, TOGAF or equivalent, would be advantageous. You will bring sound judgement, strong communication skills and a collaborative approach, together with the ability to lead through ambiguity and balance security, usability, cost and delivery priorities.
