Senior Network Engineer

Our mission at Tensorwave Cloud is to build seamless, secure, reliable, and resilient AI infrastructure at scale, eliminating barriers and challenging the status quo to empower builders and support AI innovation.

We’re seeking a Senior Network Engineer focused on implementing and operating large-scale, Arista-based RoCEv2 data center networks powering next generation AI and ML infrastructure.

You’ll work hand-in-hand with our network architect to design the infrastructure that keeps over 8,000 GPUs burring, and play a critical role in the implementation and maintenance of our next generation systems, with cluster sizes reaching over 100,000 GPUs.

You’ll work hands-on with high-speed optics, switching, and routing in production clusters and implement modern automation and tooling critical to how the network is deployed, validated, and operated.

• As a senior engineer, you are responsible for designing systems, driving technical direction, and mentoring other engineers, with demonstrable examples of architectures you’ve owned and teams you’ve influenced
• Design, deploy, and operate large-scale Arista-based RoCEv2 data center networks supporting AI and ML clusters from thousands to 100,000+ GPUs
• Own congestion management and performance tuning across RDMA fabrics, including PFC, ECN, and DCQCN, in production environments
• Implement and maintain automation, validation, and observability tooling using Python, Ansible, Terraform, and modern Dev Ops workflows
• Ensure high availability and reliability across multi-tenant environments by leading operational excellence, incident response, and continuous improvement

• Bachelor’s degree in Computer Science, Electrical Engineering, or a related technical field, or equivalent practical experience
• Deep experience with RDMA and RoCEv2 in large-scale production data centers supporting AI or HPC workloads
• Strong Arista expertise, including EOS, hardware platforms, and operating high-speed Ethernet fabrics
• Proven knowledge of congestion management and performance tuning using PFC, ECN, and DCQCN
• Hands‑on experience with high-speed optics and cabling including 400G, 800G, and AEC, AOC, DAC, and structured cabling in dense environments
• Automation and operations mindset, with experience using Python, Ansible, Terraform, Git, and observability tooling in always-on production systems

We’re looking for resilient, adaptable people to join our team, people who believe in the mission and think at massive scale. The solutions that worked on a handful of devices will not work  prepared to be pushed daily, to learn a lot, and define what is actually possible.

In addition to a competitive salary, we offer a variety of benefits to support your needs, including:

• Stock Options
• 100% paid Medical, Dental, and Vision insurance
• Life and Voluntary Supplemental Insurance
• Short Term Disability Insurance
• Flexible Spending Account
• 401(k)
• Flexible PTO
• Paid Holidays
• Parental Leave
• Mental Health Benefits through Spring Health
