NSCALE OPERATIONS APAC PTE. LTD. Hiring! Full Time DC Network - Connectivity Engineer, APAC in , Earn up to SGD 29,000 - Ricebowl

What You'll Be Doing

DC Fabric & Switching

• Deploy, configure, and maintain NVIDIA networking platforms (InfiniBand and/or Spectrum Ethernet) supporting GPU clusters and AI compute workloads.
• Build and operate access switching, east-west DC fabric, OT/IoT switching, and server-edge connectivity.
• Manage out-of-band (OOB) network infrastructure including server management ports, OOB switching, and management VRF segmentation.
• Maintain accurate port inventories, cabling records, and as-built documentation across all DC switching layers.

WAN Edge & Routing

• Terminate and manage lit carrier services (100G, 400G, 800G+) from carrier demarc into Nokia SR1 routers.
• Configure and maintain BGP, VRF, and routing policies to support customer and service segmentation and GPU farm/service pod access.
• Ensure WAN edge configurations align with Nscale's global network standards and service delivery requirements.
• Support product, service, and network segmentation across the full stack — from server management port to WAN edge.

External Connectivity & Cloud Exchange

• Manage technical delivery and validation of carrier circuit handoffs, including coordinating build-ins and demarc acceptance testing.
• Enable and support cloud exchange connectivity via platforms such as Megaport and Equinix Fabric.
• Support customer direct connect and network edge services, including cloud network enablement and cloud exchange integrations.
• Act as the technical counterpart to carriers and connectivity partners for service delivery, validation, and escalation — working alongside Nscale's sourcing and commercial teams.

Physical & Optical Layer

• Manage intra-DC fibre plant, optical patching, and interface connectivity.
• Accept and validate lit service handoffs at the carrier demarc point.
• Maintain accurate physical layer documentation including fibre records, port inventories, and as-built records

Testing & Validation

• Execute end-to-end circuit and service validation testing at each stage of network build, commissioning, and change activity.
• Use optical test equipment including OTDRs, optical power meters, and optical spectrum analysers for physical layer acceptance and fault diagnosis.
• Conduct network-layer testing using appropriate software tools and platforms to validate routing, segmentation, VRF behaviour, and service reachability.
• Develop and maintain standardised test plans, acceptance criteria, and validation checklists for consistent and repeatable network commissioning.
• Perform regression and smoke testing following maintenance windows, software upgrades, and configuration changes.
• Document all test results, findings, and sign-off records in line with Nscale's operational procedures.

Engineering & Operations

• Own the full lifecycle of network infrastructure — build, configure, test, validate, support, and maintain.
• Monitor network performance, proactively identify and resolve issues, and lead incident resolution across all network layers.
• Maintain and contribute to internal build guides, runbooks, and operational procedures.
• Support capacity management, scheduled maintenance, and infrastructure audits across the APAC DC estate.

About You

• Bachelor's degree or higher in Network Engineering, Telecommunications, Computer Science, Electrical Engineering, or a related discipline — or equivalent hands-on professional experience.
• Minimum 5 years of hands-on experience across DC networking, WAN edge, and connectivity engineering in hyperscale or large-scale data centre environments.
• Proven experience with Nokia SR routing platforms (SR1 or equivalent) including BGP, VRF, and service segmentation configuration.
• Hands-on experience with NVIDIA networking platforms (InfiniBand and/or Spectrum Ethernet) in GPU or HPC environments.
• Strong working knowledge of DC switching, access networking, OOB/management network design, and OT/IoT network segments.
• Experience with cloud exchange platforms (Megaport, Equinix Fabric, or equivalent) and customer direct connect/cloud network enablement.
• Solid understanding of physical and optical layer infrastructure — fibre plant, optical interfaces, demarc acceptance, and test equipment.
• Proficiency with optical and network test equipment including OTDRs, optical power meters, and network diagnostic and monitoring tools.
• Ability to work across the full network stack — from server management port to WAN edge — with equal confidence at each layer.
• Experience working with carriers and connectivity partners in a technical delivery, validation, and escalation capacity.
• Familiarity with network automation and programmability (Ansible, Python, OpenConfig, NETCONF) is beneficial.
• Knowledge of the APAC carrier ecosystem, regional IX landscape, and subsea connectivity is a plus.
• Bilingual skills (Mandarin or Japanese) are advantageous given the regional remit.
