Senior Systems Software Engineer, Kubernetes Scale - DGX Cloud

The DGX Cloud organization at NVIDIA brings together cutting‑edge hardware and software innovation to deliver industry‑leading accelerated computing for the world's most adventurous AI workloads. We're a team of innovative engineers dedicated to solving some of the world's biggest challenges, constantly driving advancements, and impacting millions of lives worldwide! What you’ll be doing: Drive end‑to‑end performance and scale characterization for the NVIDIA DGX Cloud software stack, from Kubernetes control and data planes through NVIDIA components such as GPU Operator, Network Operator, DCGM, NIM, and distributed inference serving, following issues from orchestration down to the metal. Collaborate with AI researchers, developers and customers to develop innovative, automated tests that simulate real user workloads using custom-built and leading open-source tools and frameworks. Deep‑dive into performance and scale issues in complex distributed systems, including interactions between Kubernetes and the NVIDIA software stack, to identify and resolve root causes. Design and develop monitoring, reporting and analysis tools for performance and scale testing across software, GPU and CPU resources. Triage, debug and root‑cause issues related to operating Kubernetes clusters at ultra‑large scale, ensuring reliability and efficiency. Build and maintain a high‑velocity framework that enables continuous, always‑on performance and scale testing via a modern CI/CD pipeline. Document research, methodologies and results clearly and concisely, and present findings at internal and external venues, including community conferences such as KubeCon and GTC. Engage efficiently with upstream communities — including Kubernetes, CNCF and NVIDIA open‑source projects — to validate performance and scalability of AI workloads early and help shape design and development decisions. What we need to see: 8+ years of experience in Computer Architecture, Networking, Storage systems, Accelerators and a Bachelors/Masters in Engineering (preferably Electrical Engineering, Computer Engineering, or Computer Science) or equivalent experience. Expertise in Kubernetes and familiarity with related CNCF projects. Background in working with large‑scale parallel and distributed accelerator‑based systems. Expertise optimizing performance and AI workloads on large‑scale systems. Experience with performance modeling and benchmarking at scale. Proficiency in Golang/Python. Background with the NVIDIA software ecosystem in both training and inference domains. Expertise with at least one of public CSP infrastructure (GCP, AWS, Azure, OCI, etc.). Ways to stand out: Strong operational experience with any one of the Kubernetes distributions; prior experience scaling Kubernetes clusters to ultra‑large node and object counts; demonstrated history of working in the open‑source community; excellent communication and interpersonal abilities; PhD in relevant areas. #J-18808-Ljbffr
