The incumbent is responsible for the design, implementation, configuration, integration, testing and commissioning of network and systems infrastructure supporting ELV and infrastructure projects. The role requires strong hands-on competency in enterprise networking, servers, GPON and system integration, including the design and implementation of High Availability (HA), redundancy and failover requirements to ensure reliable and resilient system operation.

• Design, implement, configure, test and commission network and systems infrastructure for ELV and infrastructure projects.
• Develop and review network architecture, including topology, IP addressing, subnetting, VLANs, routing, bandwidth and redundancy requirements.
• Configure and troubleshoot Layer 2/3 managed switches, including VLANs, trunking, STP/RSTP/MSTP, LACP, switch stacking and routing.
• Configure and troubleshoot routers, firewalls and network security policies, including segmentation, access control and secure system connectivity.
• Design and implement High Availability (HA) and network redundancy, including redundant paths, uplinks, switch stacking, link aggregation and failover mechanisms.
• Install, configure and troubleshoot physical and virtual servers, including Windows Server, virtualization, NIC teaming, storage and RAID.
• Support the design, configuration and troubleshooting of GPON and fibre infrastructure, including OLT, ONT/ONU and optical splitters.
• Integrate network and server infrastructure with ELV systems including CCTV, VMS, Access Control, Intrusion Detection and other IP-based systems.
• Perform troubleshooting and root cause analysis across network, server and application layers, coordinating with vendors/principals where required.
• Conduct and support UAT, SAT, integration testing, performance testing and system commissioning.
• Review technical designs to identify capacity constraints, compatibility issues, cybersecurity risks, single points of failure and other technical risks.
• Prepare and maintain technical documentation including network diagrams, IP/VLAN schedules, switch/firewall/server configurations, system architecture, configuration backups, test reports and as-built documentation.
• Provide technical support and guidance to Project Managers, Project Engineers and site teams throughout implementation, testing, commissioning and handover.
• Participate in technical discussions, design reviews and project meetings with customers, consultants, contractors, vendors and principals.
• Support pre-sales activities including technical evaluation, solution design, equipment selection and preparation of network and systems architecture.

• Preferably Diploma / Degree in Information Technology / Computer Engineering / Network Engineering / Electrical & Electronics Engineering or related discipline.
• 3 – 5 years of relevant experience in network, systems, ELV or infrastructure projects.
• Strong understanding of TCP/IP networking, IPv4 addressing, subnetting, VLANs, Layer 2 / Layer 3 switching and routing.
• Hands-on experience in configuration and troubleshooting of enterprise managed network switches.
• Good understanding of network architecture, network segmentation, High Availability, redundancy and failover concepts.
• Knowledge and experience in server installation and configuration, including Windows Server and virtualization environments.
• Working knowledge of GPON and fibre network architecture.
• Ability to understand system architecture and the interaction between network infrastructure, servers, storage and ELV applications.
• Strong troubleshooting and analytical skills with the ability to diagnose issues across network, server and system layers.
• Ability to interpret project specifications, system architecture diagrams, network diagrams and technical requirements.
• Strong interpersonal, customer management and communication skills.
• A good team player with the ability to multi-task.
• Driven, self-motivated and able to work independently.
• Willing to provide on-site technical support and participate in testing and commissioning activities when required.
