Senior Network Software Validation Engineer – AI Clusters

About this role

NVIDIA is the world leader in accelerated computing, powering the AI revolution across the world's largest data centers, clouds, and supercomputers. Within NVIDIA, the Networking Business Unit (NBU) builds the high-speed interconnect—including Ethernet, InfiniBand, NVLink, and BlueField DPUs—that connects thousands of GPUs into a single AI supercomputer, moving data at the scale and speed required by the world's most demanding AI workloads.

NVIDIA is looking for a Senior Network Software Validation Engineer to join our Network Cluster Solutions (NCS) Validation group. You will work on validating advanced networking solutions across complex NVIDIA AI cluster environments. The group is a high-performance engineering force that treats validation as a first-class software problem. We build systems, frameworks, and benchmarks that prove the correctness, reliability, and performance of NVIDIA networking solutions at scale. This role combines the development of validation methodologies and automation tools with hands-on debugging, performance analysis, and investigation of cutting-edge AI networking technologies at scale.

What You'll be Doing:

• Design validation methodologies, review product requirements, and develop comprehensive test plans for networking technologies in large-scale AI cluster solutions.
• Develop and maintain automation tools and scripts for test execution, environment setup, log collection, and data analysis.
• Execute functional, regression, performance, scale, and reliability testing across networking and AI cluster solutions.
• Own end-to-end investigation of complex customer issues by reproducing real-world scenarios, analyzing logs, telemetry, packet captures, and system metrics to identify functional issues and performance bottlenecks, triaging problems across the hardware and software stack, and driving them to root cause and resolution.
• Read and understand source code (C/C++/Python) to investigate defects, validate fixes, and improve l...
