Job description

The Cybersecurity Ops and Cloud Security Manager is responsible for establishing, managing, and continuously enhancing the organisation’s cybersecurity operations capability, with a focus on cloud environments, IoT platforms, and smart facility management systems.

The role ensures that the organisation maintains operational readiness to detect, respond to, and recover from cybersecurity incidents, and that all systems comply with ISO/IEC 27001 and related standards.

This position is critical in mitigating cybersecurity risks across ongoing digital and smart infrastructure projects, where the absence of in house operational expertise would expose the organisation to significant vulnerabilities.

    • Identity and Access Management (IAM)
    • Security monitoring and logging (SIEM/SOAR)
    • Data protection controls (encryption, DLP)
    • Secure configuration and posture management (CSPM)
  • Ensure secure integration between cloud systems and on‑premise / IoT environments.
  • Conduct cloud security assessments and remediation tracking.
• D. IoT & Smart Facility Security Operations
  • Oversee operational security of IoT devices, smart building systems, and facility management platforms.
  • Monitor vulnerabilities across OT and IoT ecosystems, including BMS, SCADA, and sensor networks.
  • Implement network segmentation and zero‑trust principles across IT/OT convergence environments.
  • Establish patch management, firmware updates, and lifecycle controls for connected devices.
• E. Threat Monitoring & Vulnerability Management
  • Establish continuous monitoring capabilities using SIEM/SOC tools.
  • Lead vulnerability scanning, penetration testing coordination, and remediation tracking.
