Support network-related integration with Zscaler, Microsoft Sentinel, Defender, Entra ID, logging, monitoring, and other security services
Provide technical leadership through architecture decisions, mentoring, peer review, standards, and calm coordination during complex implementations and incidents
Coordinate internal teams, PETRONAS Group stakeholders, vendors, MSPs, consultants, and carriers, and contribute to roadmaps, business cases, budgets, and investment recommendations

Working knowledge of network security principles and recognized frameworks such as NIST CSF, ISO 27001, or CIS Controls, with the ability to apply them to network and infrastructure design
Experience leading complex technical changes through design, risk assessment, approval, implementation, testing, rollback readiness, and operational handover
Strong technical documentation skills, including architecture diagrams, standards, operating procedures, change records, and recovery information
Strong communication and leadership skills, including mentoring, influencing without formal authority, coordinating cross-functional teams and service providers, and explaining technical risks and options.
