Staff Network Engineer

About TensorWave Our mission is simple: deliver seamless, secure, reliable, and resilient AI compute at scale. We've built a versatile cloud platform that eliminates infrastructure barriers, empowering builders to focus on innovation instead of fighting their stack. Because breakthrough AI should move at the speed of ideas, not infrastructure. About the Role We’re seeking a Staff Network Engineer (L6/L7) focused on designing, scaling, and optimizing large-scale RoCEv2 data center networks powering next-generation AI and ML infrastructure. You’ll work closely with network architects and infrastructure leadership to execute network designs and ensure operational stability as we scale cluster sizes to over 100,000 GPUs. You will drive multi-team technical direction, influence cross-functional outcomes, and own critical components of network performance and reliability. You’ll remain hands-on with high-speed optics, switching, routing, and congestion management in production clusters, while developing the standards and automation tooling that other engineers build and operate against. What You’ll Do • Set multi-team technical direction and influence cross-functional network architecture decisions to ensure seamless infrastructure scaling. • Design, deploy, and optimize large-scale RoCEv2 data center networks supporting AI and ML clusters from thousands to 100,000+ GPUs. • Implement and tune congestion management protocols across RDMA fabrics, including PFC, ECN, and DCQCN, based on real production telemetry. • Build and standardize automation, validation, and observability patterns that prevent misconfiguration and reduce manual operational overhead. • Serve as a senior technical escalation point for complex network failures and actively mentor mid-level engineers in advanced troubleshooting and design. Who You Are Required Qualifications • Bachelor’s degree in Computer Science, Electrical Engineering, or a related technical field, or equivalent practical experience. • Extensive experience deploying and operating RDMA and RoCEv2 networks in large-scale production environments supporting AI or HPC workloads. • Advanced knowledge of switching hardware and 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, AEC, AOC, DAC, and structured cabling at scale. • Strong automation mindset, with experience using Python, Ansible, Terraform, Git, and production observability tooling. • Demonstrated ability to autonomously solve complex, novel problems and translate broad architectural goals into executable project plans. What We Offer • Stock Options • 100% paid Medical, Dental, and Vision insurance for Employees • Company Health Savings Account Contributions • 100% paid Short Term and Long Term Disability Insurance for Employees • Life and Voluntary Supplemental Insurance Options • Other Insurance Options, such as Pet & Legal Insurance • Various Supplementary Health Benefits, such as discounted Virtual Healthcare Appointments and Serious Illness Support • Flexible Spending Account • 401(k) • Employee Assistance Program • Flexible PTO • Paid Holidays • Parental Leave • Other In-Office Perks Equal Employment Opportunity TensorWave is an Equal Opportunity Employer.
