WHAT YOU'LL DO
Technical Leadership & Architectural Ownership: Lead, mentor, and technically guide a team of kernel engineers to deliver high-quality, resilient storage drivers and middleware components on time, fostering a culture of technical excellence.
Protocol Optimization & Upstreaming: Drive the performance profiling, tuning, and optimization of the Linux storage target and initiator stacks (including NVMe over Fabrics and FC-SCSI), directly contributing enhancements and bug fixes back to the upstream Linux kernel.
System Resilience & Debugging: Solve the industry's most complex, low-level SAN congestion, multipathing, and kernel-level bottlenecks to maximize IOPS and bandwidth while enhancing system self-healing and link health.
Ecosystem Integration: Partner with major Fibre Channel and fabric vendors (such as Cisco and Broadcom) to seamlessly integrate state-of-the-art PCIe Gen4/Gen5 and HBA technologies into the Pure Storage ecosystem.
End-to-End Quality & Validation: Own the strategy for internal Linux kernel maintenance and test automation frameworks, ensuring robust validation of supported SAN configurations and highly predictable field behavior.
WHAT YOU BRING
Kernel & Driver Expertise: Proven expertise writing, debugging, and optimizing low-level Linux/Unix device drivers, with deep hands-on command of interrupt handling, memory management, NUMA optimization, and lock contention analysis.
Advanced Storage Protocol Mastery: Deep technical understanding of SAN architecture and storage protocol stacks, including Fibre Channel (FC-FS, FCP, FC-NVMe) and NVMe over Fabrics (RoCE, TCP, FC), alongside a strong grasp of SAN congestion mechanisms like buffer-to-buffer credits.
Systems Systems Tooling & Performance Profiling: Mastery of low-level diagnostics and profiling tools such as perf, ftrace, eBPF, blktrace, or crash to identify and resolve complex system transport bottlenecks.
Engineering Leadership: Demonstrated ability to technically steer complex projects from conception to deployment, mentor peer engineers, and collaborate cross-functionally with external technology partners.
Polyglot Development Skills: Proficiency in C and C++ for core kernel/driver development, paired with Python skills to drive advanced test automation.
