Kerja Sepenuh Masa, Senior Manager Infrastructure di PRIVASIA Technology Berhad Selangor - Maukerja

JOB SUMMARY

We are seeking a highly experienced, technically deep, and governance-driven Senior Infrastructure Manager to take full ownership of our enterprise ICT infrastructure operations. The successful candidate will bring a proven track record managing large-scale, heterogeneous server environments of 150+ servers spanning multiple operating system platforms -- including IBM AIX, Red Hat / Ubuntu Linux, and Windows Server -- within a structured, compliance-driven organisation.

This is not an entry-level leadership role. We require a seasoned professional who has personally designed, implemented, and enforced rigorous infrastructure governance frameworks -- including change control gates, configuration management, capacity governance, and lifecycle policies -- at scale. You will be expected to bring institutional knowledge of multi-platform server ecosystems, and the gravitas to drive operational excellence across a complex, mission-critical environment.

KEY RESPONSIBILITIES

1. Physical Server Management

• Manage the end-to-end hardware lifecycle for physical servers across a fleet of 150+ servers -- including procurement, rack & stack installation, maintenance, and formal decommissioning procedures.
• Oversee data centre operations ensuring optimal environmental conditions (power redundancy, precision cooling, hot/cold aisle containment, structured cabling).
• Maintain a live, accurate Configuration Management Database (CMDB) reflecting all physical assets, relationships, lifecycle status, and configuration baselines.
• Conduct rigorous capacity planning, performance baselining, and proactive hardware refresh forecasting.
• Manage OEM vendor relationships (Dell, HPE, IBM) for hardware support contracts, warranty renewals, and firmware / BIOS / UEFI / iDRAC / iLO management.
• Enforce physical security controls, asset tagging standards, and audit-readiness across all data centre hardware.

2.Virtualisation Management

• Lead the administration of enterprise hypervisor platforms -- VMware vSphere / ESXi, Microsoft Hyper-V, and IBM PowerVM / VIOS.
• Govern VM provisioning workflows including resource allocation (CPU, RAM, storage), golden template management, and automated deployment pipelines.
• Manage snapshot governance policies, storage vMotion operations, DRS rules, and cluster High Availability (HA) / Fault Tolerance (FT) configurations.
• Enforce hypervisor-level security hardening (STIG compliance, vSphere Security Configuration Guide), patch management schedules, and host configuration baselines.
• Oversee virtualisation capacity planning -- ensuring compute and storage pools are right-sized, with defined thresholds triggering formal capacity review gates.
• Manage integration between virtualisation layers and underlying SAN / NAS storage (Fibre Channel, iSCSI, NFS datastores).

3. ICT Operations Administration -- Multi-Platform Server Ecosystems

• Administer and govern a heterogeneous server environment spanning IBM AIX (LPAR / VIOS / HMC), Red Hat Enterprise Linux (RHEL) / Ubuntu Linux, and Windows Server (2016 -- 2022).
• Manage Active Directory, DNS, DHCP, Group Policy, and identity federation across the Windows estate.
• Manage LPAR configuration, PowerVM, HMC administration, and AIX OS patching via NIM (Network Installation Manager).
• Oversee kernel patching, YUM / RPM package management, SELinux policies, systemd services, and cron-based automation (Linux).
• Implement and maintain enterprise monitoring platforms (SolarWinds, Nagios, IBM Tivoli, Zabbix) covering availability, performance thresholds, and capacity trends across all 150+ servers.
• Lead Incident Management for P1 / P2 infrastructure events -- owning the full lifecycle from detection through containment, resolution, and formal Root Cause Analysis (RCA) documentation.
• Architect, test, and maintain Disaster Recovery (DR) and Business Continuity Plans (BCP), including regular failover drills and DR runbook maintenance.
• Oversee backup and recovery operations (Veeam, IBM Spectrum Protect / TSM, Commvault), ensuring RPO / RTO targets are met and backup integrity is regularly validated.

4.Infrastructure Governance, Gates & Compliance

• Design, implement, and maintain a formal Infrastructure Governance Framework encompassing Change Advisory Board (CAB) processes, approval gates, RFC workflows, and post-implementation reviews.
• Enforce strict change control gates for all infrastructure modifications -- including pre-change risk assessments, implementation plans, rollback procedures, and documented sign-off authorities.
• Own and maintain Configuration Management (CMDB) discipline, ensuring all 150+ servers are accurately documented with configuration baselines, change history, and dependency mappings.
• Drive Patch Governance across all platforms (AIX, Linux, Windows) -- maintaining patch currency schedules, exception registers, and documented risk acceptances for any deferred patches.
• Lead infrastructure audit readiness -- producing evidence packs, compliance dashboards, and policy adherence reports for internal audit, ISO 27001, and regulatory reviews.
• Establish and maintain Standard Operating Procedures (SOPs), Runbooks, and Knowledge Base articles for all recurring operational activities across the server estate.
• Govern Privileged Access Management (PAM) -- ensuring least-privilege principles, regular access reviews, and segregation of duties across all server platforms.

5. Team Leadership & Operational Governance

• Lead and coordinate a cross-functional team of System Administrators and Infrastructure Engineers across AIX, Linux, and Windows disciplines.
• Chair regular Infrastructure Operations Review meetings -- tracking open incidents, the change pipeline, capacity alerts, and overall compliance posture.
• Report infrastructure health, risk posture, and governance metrics to senior leadership and the CIO via structured monthly operational dashboards and executive summaries.
• Ensure the team operates within defined ITIL-aligned processes for Incident, Problem, Change, and Configuration Management.
• Drive a culture of documentation-first operations -- ensuring no undocumented changes, no informal configurations, and full traceability of all actions taken across the server estate.

QUALIFICATIONS & EDUCATION

• Bachelor's degree in Computer Science, Information Technology, Engineering, or a related field -- or equivalent demonstrated operational experience at scale.
• Advanced knowledge of Data Centre Infrastructure Management (DCIM) principles and tooling.
• Formal training or academic grounding in ITIL Service Management or an equivalent IT governance framework.
• Proven track record managing enterprise-grade, multi-platform server environments at scale (150+ servers).
