Jobbeschreibung

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.

Job Description:

• 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.

Job Requirements:

• Preferably Diploma or 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.
