Principal Software Engineer - HW/SW in Fleet Infrastructure

Partner with broad teams to design, develop, validate, debug, and optimize infrastructure software across OS, firmware, fleet health, hardware repair, telemetry, and monitoring areas. Lead hardware and firmware reliability architecture, including health telemetry, diagnostics, failure detection, predictive insights, and remediation automation. Drive failure analysis and root cause investigation for critical live-site incidents involving hardware, firmware, OS, storage, networking, or infrastructure platforms, and drive durable improvements that reduce recurrence. Establish engineering standards, observability patterns, and operational mechanisms that improve fleet availability, reduce deployment risk, and strengthen hyperscale infrastructure operations. Evolve M365 substrate infrastructure strategy for AI and agentic workloads across compute, memory, storage, and networking domains. Influence cross-organizational technical direction, communicate complex tradeoffs clearly, and help teams make durable architecture decisions. Mentor early in career engineers.
