Overview
The Windows Servicing & Delivery (WSD) team investigates and remediates security vulnerabilities and high-severity reliability issues across the Windows platform. The Storage & File Systems team within WSD owns NTFS, ReFS, Storage Spaces Direct (S2D), Windows Server Failover Clustering (WSFC), Cluster Shared Volumes (CSV), the Volume Shadow Copy Service (VSS), and the full Windows storage driver stack — from NVMe and iSCSI miniport drivers through to the file system minifilter layer and user-mode storage management APIs.
This Senior Software Engineer role sits at the intersection of kernel engineering and enterprise customer reliability. You will resolve the most complex ICMs escalated by top-tier enterprise and cloud customers — issues that have defeated Tier 1 and Tier 2 support and require deep ownership of source code, cluster state machines, and file system on-disk structures. Alongside security vulnerability work, you will own reliability fixes for S2D rebuild storms, CSV failover edge cases, NTFS metadata corruption,



and NVMe queue-depth exhaustion scenarios that impact Fortune 500 production environments.
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.

Responsibilities
Own end-to-end resolution of critical ICMs escalated from top enterprise customers — analyze memory dumps, ETW traces, Storage Spaces logs, and cluster event logs to root-cause failures in S2D, WSFC, CSV, NTFS, and ReFS that cannot be resolved by field support.
Investigate and fix security vulnerabilities in the Windows storage stack: privilege escalation through NTFS reparse points and junctions, information disclosure via uninitialized kernel pool in file
