Head of Cyber Security Architecture

We are partnering with a leading bank with a significant footprint in Singapore. As the bank accelerates its digital transformation, incorporating Generative AI (GenAI) and Machine Learning into core banking services, the complexity of the threat landscape is evolving.

We are looking for a visionary Head of Cyber Security Architecture to lead the strategic design of the bank's security posture. This is a regional leadership role requiring a balance of technical authority and executive stakeholder management. You will be the linchpin between business innovation and regulatory resilience, ensuring the bank remains robust against sophisticated threats while securely enabling the adoption of cutting-edge AI technologies.

The Head of Cyber Security Architecture will be the technical and strategic authority responsible for defining the bank's security posture across all domains.

• Strategic Architecture & Roadmap: Define and execute the comprehensive enterprise security architecture roadmap, ensuring alignment with the bank's regional IT strategy and risk appetite.
• AI Security & Governance: Spearhead the security strategy for the adoption of Generative AI (GenAI) and Large Language Models (LLMs). Establish the necessary guardrails for data privacy, model integrity, and ethical AI usage.
• Regulatory Compliance (MAS): Ensure all architectural designs are strictly aligned with the MAS Technology Risk Management (TRM) Guidelines. Specifically, oversee compliance with MAS FEAT principles for the secure implementation of Artificial Intelligence.
• Cloud & Zero Trust Leadership: Architect the secure deployment of multi-cloud environments (AWS/Azure) and drive the transition to a modern Zero Trust security model across the entire estate.
• MLOps Security: Define and enforce security requirements for MLOps pipelines, ensuring that AI models are resilient against adversarial attacks and that training data is protected in line with the PDPA.
• Executive Advisory: Act as the chief security architecture advisor to the CIO, CISO, and business heads, effectively translating complex technical risks into clear commercial and strategic insights.
• Governance & Review: Chair the Security Architecture Review Board (SARB), providing the final technical sign-off for all major technology initiatives, new product launches, and third-party integrations.
• Team Leadership: Lead, mentor, and expand a high-performing team of security architects, fostering technical excellence and domain specialisation within the function.
