Senior Software Engineer - Storage (C/C++)

Required Qualifications

• Bachelor's Degree in Computer Science or related technical field AND 8+ years of software engineering with deep expertise in C and C++ for Windows kernel-mode development. . OR equivalent experience.
• OR equivalent experience.
• Hands-on experience with Windows storage driver stack: StorPort miniport drivers, storage filter drivers, or file system minifilter drivers — understanding of IRP flow, completion routines, and cancel-safe queue management.
• Solid grounding in Windows kernel fundamentals.
• Demonstrated ability to perform crash dump analysis and live kernel debugging using WinDbg.
• Working knowledge of NTFS on-disk structures: MFT record layout, attribute types, USN journal, and the NTFS log file for crash recovery.
• Familiarity with ReFS (Resilient File System): B+ tree metadata structure, integrity streams, block cloning, and the differences in crash recovery model versus NTFS.
• Experience debugging file system corruption scenarios: cross-linked clusters, orphaned MFT records, directory entry inconsistencies, and reparse point cycles.
• Understanding of Windows file system minifilter architecture: altitude registration, pre/post operation callbacks.
• Hands-on experience with Windows Server Failover Clustering (WSFC): quorum models (Node Majority, Disk Witness, Cloud Witness), cluster network configuration, and the cluster API.
• Deep understanding of Cluster Shared Volumes (CSV): CSV file system (CSVFS) redirected vs. direct I/O modes, CSV ownership arbitration, and coordination with the Storage Bus Layer.
• Experience with Storage Spaces Direct (S2D): storage pool creation, virtual disk provisioning, cache tier architecture (NVMe + SSD + HDD), fault domain awareness, and rebuild/rebalance behavior under node and drive failure.
• Familiarity with storage connectivity protocols in clustered environments: SMB Direct (RDMA), iSCSI multipath (MPIO/DSM), NVMe-oF, and Fibre Channel HBA integration with StorPort.
• Proven ability to work high-urgency customer escalations (ICMs / CritSits): triage under time pressure, communicate root cause to non-technical stakeholders, and deliver targeted fixes through the Windows servicing pipeline.
