About
WDC is a leading innovator in Enterprise Storage Networking. We are looking for a passionate and skilled DevOps Engineer with Linux Kernel and tools expertise to build end-to-end automation for firmware development and system validation. Create custom Linux kernel patches to enable feature development and also upstream kernel changes. Strong PCIe/NVMe protocol knowledge; comfortable with Ethernet and PCIe analyzers. Today's exceptional challenges require your unique skills. Together, we can build the future of data storage. Responsibilities: Design reusable Python/Bash libraries and CLIs for FW build/test/regressions. Integrate Docker, Jenkins/GitLab CI/Azure DevOps, Gerrit/Git, Jira, test mgmt systems. Create custom Linux Kernel patches and upstream Enable FW developers with unit test harnesses, lint/format, emulation adapters. Implement telemetry/ETL pipelines for coverage, reliability, and performance KPIs. Collaborate across FW/HW/ASIC; document standards and best practices. Minimum Qualifications: System level programming in C (and some assembly) with a strong track record of shipping low level code Deep understanding of Linux OS internals: processes, scheduling, memory management (paging, MMU, slab/slub allocators), VFS, block subsystems, networking stack. Direct experience modifying or upstreaming Linux kernel code, not just using kernel APIs. Comfort with hardwaresoftware boundaries: interrupts, DMA, device registers, firmware handoff, PCIe, IOMMU, ACPI/DT, boot sequence. Automation experience in FW/system validation. Expert Python; linux ; kernel modules; Bash; working C/C++ for FW hooks; PowerShell as needed. PyTest/Robot Framework; hardware-in-the-loop experience. CI/CD expertise (pipelines-as-code, artifacts, secrets, flaky test mgmt). PCIe/NVMe, DMA/interrupts, RTOS; lab debug with logic/protocol analyzers. Tool integration with Gerrit/Git, Jira, test mgmt, results DBs. Proven log analysis and failure bucketing; strong communication/documentation. Preferred: Proficiency with Linux kernel build system, Kconfig, cross-compilation, git bisection, patch submission workflow. Prior contributions to LKML or to a major subsystem tree. Ability to follow kernel coding style, patch series etiquette, and review cycles. Strong debugging skills: perf, ftrace, bpftrace, kgdb, crash dumps, static analysis. Experience with CI for kernel builds and regression testing, especially with custom hardware. CMake/Bazel; cross-compilers; artifact signing. Data stack (SQLite/PostgreSQL, Pandas); Grafana/PowerBI dashboards. Prior storage FW or networking ASIC validation experience.
