Principal Software Engineer, Rack-Scale System Software — CSP Engagements

We're looking for a Principal Software Engineer to join our CSP Engagements team as the technical focal point for rack-scale system SW/FW, working with CSP engineering teams to ensure they can deploy, monitor, and operate these systems reliably at fleet scale. In this role, you will collaborate with NVIDIA's cross-functional rack-scale system SW/FW engineering teams with dedicated CSP-facing technical leadership. Your focus is on the system-level software that manages, monitors, and recovers the rack as a whole — fabric management, GPU/NVSwitch error handling and recovery, health telemetry APIs, firmware update orchestration, and SW-driven serviceability. You will drive work streams with CSP engineering teams to build shared understanding of the architecture, incorporate their operational feedback, and ensure integration readiness.What you'll be doing:Drive rack-scale SW/FW architecture alignment across CSP engagements — including fabric management software, link health monitoring, GPU/NVSwitch error handling, SW/FW serviceability features (e.g., hot-plug support, component isolation, firmware-driven recovery), and multi-component firmware orchestrationDrive technical work streams with CSP engineering teams on rack-scale system software — ensuring they deeply understand fabric management, NVSwitch behavior, error handling and recovery policies, health telemetry APIs, and SW/FW-controlled recovery operationCapture and synthesize CSP engineering feedback on rack-scale system software — health monitoring APIs, SW-driven serviceability workflows, firmware update orchestration, and error recovery behavior — champion that feedback into NVIDIA's architecture decisionsCollaborate with multi-functional teams to ensure customer operational requirements are reflected in system software and firmware developmentIdentify cross-CSP patterns in rack-scale SW/FW issues, error handling behavior, and system configuration practices — drive documentation, tooling, and test strategy improvements as a resultCollaborate with execution teams on left-shift strategy — ensuring customer-side SW/FW integration work is identified early and completed ahead of hardware availabilityMake critical technical decisions on rack-scale system SW/FW tradeoffs and mitigate execution risks through early engagement with CSP engineering teamsWhat we need to see:15+ years of experience in system software, platform firmware, or large-scale distributed systems engineering. BS or MS in Computer Science, Electrical Engineering, or related field (or equivalent experience)Deep understanding of rack-scale system software challenges: multi-component coordination, error propagation, health monitoring, and serviceability / reliabilityExperience with fabric management software, cluster management, or system-level orchestration frameworks. Familiarity with firmware architectures and update lifecycle management (multi-component update sequencing, rollback, recovery)Understanding of error handling and recovery design patterns in distributed systems — fault isolation, retry policies, graceful degradationExperience with health monitoring and telemetry systems: health scoring, event correlation, API design for fleet-level observabilityUnderstanding of GPU or accelerator system software (drivers, device management, power management) is a strong plusCustomer obsession — genuine passion for understanding how CSPs operate sophisticated systems at fleet scale and simplifying their experienceProven success providing technical leadership across organizational boundaries and influencing system software design without direct authority. Strong communication — ability to translate complex system software architecture into actionable mentorship for customer engineering teamsWays to stand out from the crowd:Experience with NVIDIA NVSwitch, NVOS, or GPU fabric management softwareBackground in system software for large-scale clusters at a hyperscaler (cluster management, fleet orchestration, health platforms)Experience crafting error handling and recovery frameworks for multi-component systems (hundreds or thousands of coordinating devices)Familiarity with GPU or accelerator fleet operations — driver lifecycle, firmware rollout strategies, health-based schedulingUnderstanding of how system software decisions impact serviceability, availability, and operational cost at fleet scaleNVIDIA’s invention of the GPU in 1999 fueled the growth of the PC gaming market, redefined modern computer graphics, and revolutionized parallel computing. More recently, GPU deep learning ignited modern deep learning — the next era of computing — with the GPU acting as the brain of computers, robots, and self-driving cars that can perceive and understand the world.
