Senior Cloud Network Operations Engineer

Salary: RM 6,000 – RM 9,000 per month

About the role

Monitor the full network estate 24x7 — switches, routers, optical transport — tracking device health, link bandwidth, and traffic load in real time. Work alongside architecture and delivery teams to hunt down the hard stuff: microsecond-level jitter affecting GPU-to-GPU communication, NCCL throughput degradation, and other performance issues unique to high-performance AI networks. Act as the technical interface for internal R&D teams and key customers, handling network change requests in real time: traffic isolation, VLAN adjustments, routing policy changes, temporary bandwidth upgrades, and more.

Key responsibilities

• Monitor the full network estate 24x7 — switches, routers, optical transport — tracking device health, link bandwidth, and traffic load in real time

• Keep a close eye on AI-specific network signals: the indicators that hint at a problem before it becomes one

• Own incident response for network outages, link failures, and device-down events — moving fast, closing the loop, and hitting SLA targets every time

• Work alongside architecture and delivery teams to hunt down the hard stuff: microsecond-level jitter affecting GPU-to-GPU communication, NCCL throughput degradation, and other performance issues unique to high-performance AI networks

• Manage the full ticket lifecycle for routine network requests — fault reports, access requests, resource allocation — from creation through escalation to resolution

• Produce regular network health reports and post-incident reviews; build out the team's knowledge base so every hard-won lesson is captured

• Act as the technical interface for internal R&D teams and key customers, handling network change requests in real time: traffic isolation, VLAN adjustments, routing policy changes, temporary bandwidth upgrades, and more

• Execute changes under a rigorous change management process — writing the change plan, running the implementation, and keeping the blast radius on AI training jobs as close to zero as possible

About you

• 5+ years of network operations experience in large-scale internet, cloud, carrier NOC, or datacenter environments

• Degree in CS, Telecoms, Electronics, or similar

• Strong hands-on knowledge of BGP, OSPF, VXLAN, EVPN, and ECMP — both configuration and the underlying forwarding mechanics

• Comfortable at the CLI of enterprise-grade switches and routers from vendors like NVIDIA Spectrum/Quantum, Arista, or Cisco; able to troubleshoot independently

• Working knowledge of InfiniBand or RoCEv2, and a solid grasp of lossless network congestion control — PFC, ECN, and why they matter for AI traffic

• Familiar with network monitoring tools: Zabbix, Prometheus, Grafana, Cacti, MTR, or equivalent

• Fluent in Chinese and English
