Principal, Customer Solution Engineer (Fundamentals, Performance & Reliability)

Swarm on a customer engagement to dive deep into fundamentals and improve the install-base health of strategic Windows commercial customers with hands-on technical engagement. Discover: Embed with strategic enterprise customers to understand device performance, reliability, boot and sign-in experience, battery life, application responsiveness, system resource utilization, and operational workflows. Use telemetry, traces, logs, dumps, diagnostics, and customer evidence to identify performance bottlenecks, reliability failures, regressions, and systemic issues. Build and implement technical resolution and modernize device management to resolve install base health challenges: Design and implement solutions with customers. When needed, develop prototypes, scripts, diagnostic tools, configuration changes, and implementation approaches, then validate them in customer environments to demonstrate measurable improvements. Apply solid engineering fundamentals including security, privacy, maintainability and supportability. Validate solution in customer environments to demonstrate measurable improvements. Collaborate with Windows Shell, Performance, Reliability, Update, Drivers, Servicing, Security, and other product engineering teams to investigate complex cross-product issues and drive product fixes, supportability changes, and telemetry enhancements supported by actionable customer evidence including detailed reproduction information, logs, etc., and business impact. Deliver measurable customer and business outcomes.
