As an NVIDIA Cloud and Engineering partner in Asia Pacific, you will gain skills, experience, and exposure across the AI industry and be part of shaping what this industry looks like for decades to come. We are founder-led, not a big corporate. Decisions happen fast, our leaders are accessible, and there's minimum bureaucracy between you and the work. Ownership comes early. Whatever your role, you will have a direct line to outcomes, helping shape how the business grows as we scale nationally across a long-term, large-scale roadmap. Work alongside founders and experts in AI infrastructure, energy systems and next-generation compute. What we build here has impact beyond the business. Our AI Factories are designed to operate as assets to the energy grid to actively strengthen the communities and regions they operate in rather than drawing from them. Considering applying? You don't need a perfect background to join our team. If you're driven and curious, there's a path for you. We back our people to grow into new domains and take on challenges beyond their previous experience. Role Summary The Site Manager is responsible for the end-to-end site execution of Network Layer 1 infrastructure for large-scale data center deployment projects. The role leads and coordinates subcontractors responsible for network rack move-in, rack installation, rack & stack activities, fibre optic cabling, patching, labelling, testing and associated physical network infrastructure. The Site Manager works closely with Network Engineers during Layer 2 configuration, activation and testing, ensuring physical installation issues are rapidly identified, isolated and resolved. The role also coordinates closely with the Mechanical & Electrical (M&E) team to progressively bring up power and cooling infrastructure in line with the network deployment sequence. A critical part of this role is daily troubleshooting management. The Site Manager is expected to establish clear ownership of faults, coordinate contractors and engineering resources, drive root-cause identification, remove blockers and ensure issues are followed through to closure without allowing unresolved problems to accumulate. This is a site-based, hands-on delivery role requiring strong contractor management, network installation knowledge and the ability to operate effectively in a fast-paced data center deployment environment. Network Layer 1 Construction & Installation

• Take ownership of site execution for Network Layer 1 infrastructure.
• Plan, coordinate and supervise network rack move-in, positioning and installation.
• Manage rack & stack and physical network equipment deployment.
• Coordinate installation of fibre optic cabling, copper cabling, patch panels, ODFs and associated network infrastructure.
• Manage fibre pulling, termination, splicing, patching, dressing, labelling and testing activities.
• Ensure installations comply with approved drawings, rack elevations, cable schedules, port maps, method statements and project standards.
• Ensure physical installation readiness ahead of network configuration, testing and commissioning.
• Coordinate rectification of installation defects and punch-list items. Subcontractor & Contractor Management
• Manage network installation subcontractors and specialist vendors on site.
• Translate project requirements and construction schedules into clear daily execution plans for contractors.
• Coordinate contractor manpower, materials, tools, machinery and work fronts.
• Monitor contractor productivity and installation performance against daily and weekly targets.
• Ensure contractors have required drawings, materials, access, permits and information before commencing work.
• Conduct daily coordination meetings and clearly communicate priorities and constraints.
• Hold contractors accountable for quality, productivity, safety and timely completion.
• Escalate resource or performance issues and drive corrective or recovery actions. Construction Planning & Site Coordination
• Develop detailed daily plans and short-term look-ahead plans aligned with the overall project master schedule.
• Manage construction sequencing and work-front readiness.
• Coordinate installation activities with other trades and project stakeholders.
• Identify access, material, design, resource and sequencing constraints before they impact installation.
• Coordinate closely with Project Managers, Project Engineers, Site Engineers, Network Engineers, logistics teams and other construction disciplines.
• Track physical installation progress and maintain accurate site status. M&E Interface & Progressive Power/Cooling Bring-Up
• Work closely with the M&E team to coordinate progressive power and cooling readiness in line with the network deployment sequence.
• Maintain alignment between rack installation, power availability, cooling availability and network equipment activation.
• Coordinate progressive energisation of network racks and associated infrastructure based on construction and commissioning priorities.
• Verify rack power, PDUs, grounding/bonding and associated electrical infrastructure readiness before equipment energisation.
• Coordinate with the Mechanical team to ensure cooling systems and suitable environmental conditions are available before network equipment is powered and placed under load.
• Participate in M&E readiness reviews and identify dependencies that could impact network rack bring-up.
• Establish readiness progression from rack installation to power/cooling readiness, equipment energisation, Layer 1 verification, Layer 2 configuration, network testing and commissioning.
• Coordinate with M&E, Network Engineering and Commissioning teams to develop rack, row, zone or data hall bring-up sequences.
• Track and escalate power and cooling constraints that could delay network activation or project milestones.
• Support troubleshooting where network equipment issues may be related to power, cooling, environmental conditions or other facility infrastructure. Layer 1 to Layer 2 Integration
• Act as the primary site interface between physical network installation contractors and Network Engineers.
• Ensure Layer 1 infrastructure is complete, tested and ready before Layer 2 configuration and activation.
• Coordinate with Network Engineers during switch configuration, network activation, connectivity testing and commissioning.
• Support Network Engineers in isolating whether faults originate from physical infrastructure, equipment installation, cabling or configuration.
• Coordinate physical checks, cable tracing, re-patching, fibre testing, equipment replacement and other field a
