Microsoft’s Cloud business is expanding, and the Cloud Supply Chain (CSCP) organization is responsible for enabling the hardware infrastructure underlying this growth including AI! CSCP’s vision is to empower customers to achieve more by delivering Cloud and AI capabilities at scale. Our mission is to deliver the world's computer with an industry-leading supply chain. The CSCP organization is responsible for traditional supply chain functions such as plan, source, make, deliver, but also manages supportability (spares), sustainability, and decommissioning of datacenter assets worldwide. We deliver the core infrastructure and foundational technologies for Microsoft's over 200 online businesses including Bing, MSN, Office 365, Xbox Live, OneDrive and the Microsoft Azure platform for external customers. Our infrastructure is supported by more than 300 datacenters around the world that enable services for more than 1 billion customers in over 90 countries.

The Cloud Sourcing, Spares, Security and Sustainability (CS4) organization within CSCP manages sourcing, strategy, and suppliers to provide cost, flexibility, and supply advantages that enable our org to become a world-class supply chain. Well-defined and executed sourcing and supply chain management ensures reliable, on-time performance and optimized cost, prevents urgent and unplanned investments, and provides accurate and timely information across the supply base and internally across the infrastructure organization. Our focus is on smart growth, high efficiency, and delivering a trusted experience to customers and partners worldwide.
Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.

We are seeking a high performing candidate to partner closely with leading backend service providers across OSAT, Substrate, and Test for Microsoft custom silicon projects including MAIA and Cobalt. The ideal candidate will have extensive experience working with this ecosystem.

• Drive strategic negotiations with global OSAT partners for silicon test services, optimizing rate structures, TTR, incentive frameworks, and facility commitments to balance cost, capacity, and scalability.
• Develop and operationalize should-cost models for silicon test, leveraging test time, multi-site efficiency, and asset utilization to improve unit economics.
• Partner with Demand Planning and NPI teams to secure test capacity (equipment and labor) 1-3 years ahead of ramp, ensuring readiness and minimizing supply risk.
• Contribute to custom silicon sourcing strategy, partnering across Azure hardware, engineering, and supplier ecosystems to align on technology and capacity roadmaps.
• Build and manage executive-level supplier relationships across the semiconductor value chain (Foundry, OSAT, Substrate, Test) to enable performance, continuity, and alignment.
• Ensure supply continuity through structured forecasting, supplier selection, and qualification processes aligned to engineering and business requirements.
• Drive cross-functional execution with sourcing, planning, and program teams to deliver cost, schedule, and material readiness for silicon programs.
• Lead procurement and readiness of manufacturing test hardware (e.g., probe cards, load boards) to support production ramps.
• Establish operating rigor across supplier management, including RoB, QBRs/EBRs, and performance reporting.
• Identify and mitigate supply risks, establishing escalation paths and proactive mitigation strategies across the supply base.
• Contribute to internal initiatives to improve efficiency, scalability, and resilience of Microsoft’s custom silicon supply chain.
