Network EngineerLocation: San Francisco, CA / Remote (US) • Full-Time • Travel up to 25%The RoleAndromeda's infrastructure team designs, deploys, and operates large-scale GPU clusters for AI labs and compute providers. The Network Engineer designs and brings up the networks in our GPU clusters: compute fabric, storage network, front-end, and out-of-band management. You work with the Cluster Architect on design and with deployment engineers on site through validation. You report to the Head of Infrastructure.
What You'll Own- Compute fabric: InfiniBand (NDR, XDR) and Spectrum-X Ethernet fabrics, including rail-optimized topologies and NVLink domain integration.
- Storage and front-end networks: Design and capacity planning for storage traffic, tenant access, and internet and cloud interconnect.
- Cabling and optics: Cabling plans, optics BOMs, and labeling standards integrators can build from.
- Bring-up and validation: Fabric bring-up, NCCL and fabric performance testing, and sign-off for acceptance.
- Troubleshooting: Escalation point for fabric issues during deployment and in Day 2.
- Automation: Configuration templates and tooling so each build starts from a known-good baseline.
What We're Looking For- GPU fabrics at scale: Hands-on design and bring-up of InfiniBand or RoCE fabrics for clusters of 1,000+ GPUs.
- Tooling: Experience with NVIDIA UFM and switch operating systems such as Cumulus or SONiC.
- Physical layer: Practical knowledge of optics, transceivers, and high-density cabling.
- Automation: Python and Ansible or similar for configuration and validation.
Strong Candidates May Have- NVL72: Experience with GB200 or GB300 NVL72 rack-scale systems.
- Multi-site: Data center interconnect and cloud interconnect design.
- Customer-facing: Experience working directly with customer ML infrastructure teams.
Why You'll Love It Here- Own the network design standard for our clusters
- Work on current and next-generation fabrics across many sites and customers
- High talent density, high trust team shaping the compute market
- Comprehensive benefits for you and your dependents, including healthcare, dental, and vision coverage, 401(k), and unlimited PTO
