Lead Security Architect – AI & Data

Reference: y0tycp2bkk1f8hikiuvq

We are seeking a Lead Security Architect – AI & Data to define and advance security architecture across artificial intelligence, data, analytics, and emerging digital platforms. This is a senior role for an experienced security professional who can translate complex business and technology requirements into practical, resilient, and risk-based solutions. You will establish architectural principles, patterns, standards, and reference designs that protect sensitive information throughout its lifecycle while enabling responsible innovation.

Key responsibilities will include leading security architecture reviews for AI, machine learning, cloud, data platforms, APIs, and enterprise applications; identifying threats and designing appropriate controls across identity, access management, encryption, privacy, network security, application security, monitoring, and resilience; and assessing risks associated with generative AI, model supply chains, data poisoning, prompt injection, unauthorised data exposure, and third-party services. You will partner with engineering, data, privacy, risk, compliance, and business teams to embed security by design, oversee technical exceptions, and support the development of policies and governance frameworks. The role will also involve mentoring architects and engineers, communicating security risks to senior stakeholders, and keeping security strategies aligned with evolving regulations and industry practices.

Applicants should have substantial experience in security architecture, with a strong background in data security, cloud technologies, AI or machine learning environments, and enterprise risk management. Professional certifications such as CISSP, CCSP, SABSA, TOGAF, or relevant cloud security credentials are desirable. You will bring a detailed understanding of security frameworks and standards, such as ISO 27001, NIST, Zero Trust, privacy principles, and secure software development practices. Strong analytical, communication, influencing, and stakeholder-management skills are essential, along with the ability to make sound decisions in ambiguous situations. Experience leading security transformation initiatives and working across complex, regulated environments would be highly valued.
