NVIDIA is shaping the next era of computing, where AI, accelerated computing, and high-speed networking come together to power the world’s most advanced AI systems. Within NVIDIA, the Networking Business Unit (NBU) builds the high-speed interconnect technologies — Ethernet, InfiniBand, NVLink, and BlueField DPUs — that connect thousands of GPUs into a single AI supercomputer.
NVIDIA is looking for a Technical Lead to join our Network System Validation group and lead the validation of advanced networking solutions across complex AI cluster environments. This is a deeply hands-on technical leadership role, combining ownership of the validation roadmap with technical mentoring and engineering excellence. You will develop validation methodologies and automation frameworks, while working hands-on on debugging, performance analysis, and cutting-edge AI networking technologies at scale. Join us to help push NVIDIA’s networking technologies to their limits and shape how next-generation AI infrastructure is validated.
What You’ll Be Doing
• Review system and product requirements, design validation methodologies, develop and implement comprehensive test plans, functional and performance, for networking technologies in large-scale AI cluster solutions
• Develop and maintain benchmarks, automation tools and scripts for test execution, environment setup, log collection, and data analysis.
• Lead end-to-end investigation of complex 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 logging, instrumentation, and debugging capabilities
• Collaborate deeply with software and hardware development teams to debug networking technologies, including NCCL, RoCE, RDMA, and related software components using targeted experiments and code inspection
• Profile and research AI training and inference workloads, correlating application behavior with network and system telemetry to identify scalability and performance limitations
• Document findings, communicate technical results, and continuously improve validation methodologies, automation environments, and engineering processes
What We Need To See
• B.Sc. / B.A. in Computer Science, Electrical Engineering, or equivalent experience
• 12+ years of experience in networking, system validation, or related domains
• Proven experience debugging complex production systems by forming hypotheses, designing experiments, and driving issues to root cause
• Ability to read, debug, and reason about C/C++ code (Rust or Go a plus)
• Strong scripting and automation experience using Python, Bash, and/or Ansible
• Deep understanding of distributed systems: concurrency, consistency models, fault tolerance, and large-scale system performance under stress
• Ability to drive technical alignment across teams, communicate tradeoffs clearly, and make high-quality architectural decisions at speed
• Advance AI-driven approaches to test automation: intelligent scenario generation, LLM-augmented root-cause analysis, and autonomous validation pipelines
Ways To Stand Out From The Crowd
• Experience with large-scale clusters or distributed systems
• Familiarity with NVIDIA networking solutions (ConnectX, SpecX, BlueField)
• Background in performance analysis, Kubernetes, or cloud environments
• Background in chaos testing, fault injection, or simulation systems
We have some of the most forward-thinking and hardworking people working for us. If you're creative and autonomous, we want to hear from you!
