We are seeking a senior manager to lead our cybersecurity initiatives across APAC, focusing on secure system design and implementation across operational technology (OT) and information technology (IT) environments in ports, terminals, and logistics.

Key Responsibilities:
  • Security Architecture & Design
    • Develop and maintain comprehensive security architecture blueprints for integrated OT/IT ecosystems, including supervisory control and data acquisition (SCADA), programmable logic controllers (PLCs), terminal operating systems (TOS), enterprise networks, and cloud environments.
    • Design and implement defence in depth strategies, secure network segmentation, micro-segmentation, data protection frameworks (encryption, tokenization, data loss prevention), and SIEM/SOAR integration across OT and IT.
    • Ensure compliance with relevant security policies, procedures, and regulations specific to the APAC Region (e.g., GDPR, ISO 27001, NIST, CIS, local data privacy and cybersecurity laws).
  • Security Architecture Governance
    • Define security architecture patterns aligned with our organization's cyber security architecture frameworks.
    • Lead technical reviews of OT/IT infrastructure designs, including network security, web and application security, network access control, and remote access/VPN.
    • Ensure secure development practices are embedded across the software development lifecycle.
    • Establish architectural standards, define security controls, and ensure APIs are designed, implemented, and maintained in compliance with organizational standards and policies.
    • Ensure developed code is scanned using static and dynamic scanners and APIs are scanned using API-specific security testing platforms.
  • Security Operations Integration
    • Support the integration of OT/IT telemetry into SIEM platforms, such as Microsoft Sentinel.
    • Collaborate with the security operations centre (SOC), cybersecurity operations teams, and incident response teams on architecture-related investigations.
    • Assist in designing security controls embedded in disaster recovery and business continuity plans.
