Senior Network Engineer – Deployment (APAC)
Nscale — Singapore · Hybrid · Senior
Role description
Role Overview
We're looking for a Senior Network Engineer to build and bring up the networks behind Nscale's GPU clusters across Asia-Pacific. Based in Singapore, you'll join our Deployment organisation, a build org that owns every step from hardware arrival on site through to customer acceptance.
What You Will Do
Deploy, configure, and validate high-performance Ethernet and InfiniBand fabrics for large GPU clusters at our APAC sites. Bring up front-end, storage, and management networks and WAN edge connectivity for new sites and expansions in the region.
Why It Might Be a Fit
The network is what turns thousands of GPUs into a single system. As one of our first network engineers in APAC, you'll shape how Nscale builds in the region and how quickly new clusters reach customers there.
Requirements
- 5+ years of network engineering experience in large-scale data centre, cloud, or HPC environments.
- Experience at a hyperscaler or major network vendor (e.g. Microsoft, AWS, Oracle/OCI, Cisco) or a comparable large-scale network.
- Strong hands-on knowledge of routing and switching: BGP, OSPF, EVPN/VXLAN, ECMP, and L2/L3 data centre design.
- Experience deploying and operating cluster networks, ideally including InfiniBand or RoCE fabrics.
- Familiarity with the APAC data centre and carrier landscape, including working with regional providers.
- Practical experience with network automation (Python, Ansible, or similar).
- Calm, methodical troubleshooter who can work under deadline pressure on live builds.
- Willingness to travel across Asia-Pacific as needed.
