Cloud Network / SDN Engineer

Bitdeer is a technology company focused on AI and Bitcoin mining infrastructure, including advanced cloud capabilities for artificial intelligence. The Cloud Network / SDN Engineer will design and operate networking for a large-scale, multi-tenant GPU cloud, focusing on tenant isolation, high-performance GPU interconnects, cross-region routing, network automation, security, and observability.

Responsibilities:

• Design, operate, and troubleshoot multi-tenant SDN: tenant isolation, VPC / overlay networking, and east-west / north-south traffic
• Build and tune high-performance GPU interconnect fabrics (InfiniBand / RoCE) for distributed training, including lossless config and congestion control (PFC / ECN)
• Plan and operate cross-region interconnect and routing
• Lead network change management and fast fault localization to minimize tenant impact
• Partner with Compute and Control Plane teams on network-provisioning automation
• Define network architecture standards, security boundaries, and observability

Requirements:

• 6+ years in datacenter / cloud networking or SDN
• Deep expertise in multi-tenant isolation, overlays (VXLAN / EVPN), and L2 / L3 design
• Experience with SDN controllers and network automation
• Strong troubleshooting / fault-localization under production load
• Hands-on with high-performance fabrics: InfiniBand and / or RoCE, RDMA — strongly preferred for GPU / HPC clusters
• Multi-region network design experience a plus
