The Substrate Fleet Health team is engineering the future of cloud reliability and efficiency of managing health and capacity of the Substrate Fleet. We are a high-impact team driving innovation in hardware health, fleet lifecycle management, intelligent repair systems, and proactive capacity optimization to ensure Microsoft’s hyperscale infrastructure operates at peak performance.

Our mission is bold:

• Maximize fleet availability through proactive detection and mitigation of hardware issues.
• Accelerate repair intelligence with AI-driven insights and automation, reducing repair times from hours to seconds.
• Optimize spare machine utilization and capacity forecasting across global datacenters, unlocking millions in cost savings and enabling sustainable growth.
• Enhance fleet lifecycle management by predicting failures, improving component health, and reducing stranded capacity.

We are building next-generation solutions like RepairBox vNext, Fleet Health Copilot, Unified Spare Pool, and Smart Recovery Services—systems that integrate telemetry, predictive analytics, and automation to transform how cloud infrastructure is managed and scaled.

Our culture values:

• Innovation: We challenge the status quo and pioneer AI-driven solutions for hardware health and capacity optimization.
• Collaboration: We work across Substrate, Azure, and vendor ecosystems to solve complex global challenges.
• Ownership: We take pride in delivering resilient, scalable systems that power Microsoft’s cloud.
