Note: The job is a remote job and is open to candidates in USA. TensorWave delivers secure and reliable AI compute through a cloud platform designed to remove infrastructure barriers. The company is seeking a Principal Network Engineer to own and evolve large-scale RoCEv2 data center networks supporting AI and ML infrastructure, while setting architectural standards, improving reliability, and handling complex production issues at scale.

Responsibilities

• As a Principal Engineer, you own end-to-end network architecture, make high-impact design decisions, and set technical direction across teams, with clear examples of systems you’ve defined and scaled
• Define, evolve, and standardize large-scale RoCEv2 data center networks supporting AI and ML clusters from thousands to 100,000+ GPUs
• Set and validate congestion management strategy across RDMA fabrics, including PFC, ECN, and DCQCN, based on real production behavior
• Establish automation, validation, and observability patterns that prevent misconfiguration and eliminate manual operational work
• Act as the technical escalation point for complex failures, scaling limits, and architectural tradeoffs in always-on, multi-tenant environments

Skills

• Bachelor's degree in Computer Science, Electrical Engineering, or a related technical field, or equivalent practical experience
• Deep experience designing and operating RDMA and RoCEv2 networks in large-scale production environments supporting AI or HPC workloads
• Expert-level knowledge of switching hardware and their NOS, such as Arista, Juniper, and custom solutions using SONiC, including high-speed Ethernet fabrics
• Proven hands-on experience with congestion management and performance tuning using PFC, ECN, and DCQCN
• Strong experience with high-speed optics and cabling including 400G, 800G, and AEC, AOC, DAC, and structured cabling at scale
• Strong automation mindset, with experience using Python, Ansible, Terraform, Git, and production observability tooling
• We're looking for engineers who operate comfortably at scale, make hard calls with incomplete data, and take responsibility for systems that must work under sustained load. The solutions that work on a handful of devices will not work at Exascale
