Principal Software Engineer, At-Scale Reliability and Fleet Intelligence — CSP Engagements

We're looking for a Principal Software Engineer to join our CSP Engagements team as the technical focal point for fleet-scale reliability, working directly with engineering teams of key CSP / hyperscale customers to ensure NVIDIA platforms achieve target MTBI (Mean Time Between Interruptions) in production. In this role, you will augment NVIDIA's internal software/firmware and quality teams with a dedicated CSP-facing focus. You will drive work streams with CSP engineering teams to build shared understanding of reliability software/firmware architecture, methodology, incorporate their fleet telemetry and failure data into NVIDIA's improvement priorities, and validate that reliability improvements measured in the lab translate to real customer environments. Your cross-CSP visibility enables you to distinguish systemic architectural gaps from environmental or configuration-specific issues that no single customer engagement could identify alone. What you'll be doing: • Drive reliability work streams with CSP engineering teams — ensuring shared understanding of MTBI measurement methodology, failure classification, and health monitoring architecture • Gather and synthesize CSP fleet reliability data — identify failure patterns that appear across multiple customers and champion improvements back into NVIDIA's firmware, driver, and hardware teams • Define consistent MTBI measurement methodology that works across different CSP monitoring environments and operational practices • Conduct fleet-scale failure pattern analysis using statistical methods (Pareto, survival analysis, Weibull) to classify failures as systemic, environmental, or configuration-specific • Drive fleet health monitoring integration architecture — ensure NVIDIA's health agents, telemetry, and reporting align with CSP operational workflows and automation • Define burn-in reliability test environment and cluster certification criteria in collaboration with quality teams, validating with customers that criteria are meaningful • Collaborate with CSPs to ensure reliability-related integration work (health monitoring deployment, telemetry pipeline, alerting configuration) is complete ahead of at-scale launch • Develop predictive failure models using fleet telemetry and validate their effectiveness in customer environments What we need to see: • 15+ years of experience in systems software at datacenter scale, or reliability engineering with focus on at-scale challenges. • BS or MS in Computer Science, Electrical Engineering, Statistics, or related field (or equivalent experience) • Deep expertise in multi-NUMA, rack-scale system software and firmware. Statistical failure analysis methods: MTBF/MTBI calculation, Pareto analysis, root cause classification • Experience with fleet-level telemetry and observability systems: time-series databases, anomaly detection, health scoring, event correlation • Understanding of hardware failure modes in large-scale GPU/accelerator deployments — ability to classify and prioritize across compute, interconnect, memory, power, and thermal domains • Experience defining or operating burn-in, stress testing, or certification frameworks for complex hardware systems. Familiarity with predictive maintenance or anomaly detection approaches applied to fleet health data • Customer obsession — genuine passion for understanding fleet reliability challenges at scale and translating them into actionable engineering priorities • Strong communication — ability to present statistical reliability findings to both deep technical audiences and executive leadership. Demonstrated success driving cross-functional improvements across hardware, firmware, and software teams without direct authority Ways to stand out from the crowd: • Experience in fleet reliability at a hyperscaler (hardware health, fleet reliability at leading CSP/Hyperscaler) • Familiarity with NVIDIA GPU error taxonomy (Xid errors, NVLink error counters, thermal events, CPER records) • Experience building health scoring or predictive failure models for accelerator or HPC infrastructure • Background in defining MTBI/MTBF measurement standards or certification programs for complex multi-component systems • Understanding of how reliability data flows from device firmware through telemetry pipelines to fleet-level dashboards and automated remediation NVIDIA is leading the way in groundbreaking developments in Artificial Intelligence, High-Performance Computing and Visualization.
