Broadcom
We are seeking a highly skilled and experienced Device Driver Developer to join our core driver development team. This role involves the design, development, optimization, and debugging of high-performance Ethernet network interface card (NIC) drivers that operate at the kernel level. The ideal candidate will have deep expertise in low-level programming, network protocols (L2/L3), and kernel internals across multiple operating systems, including Linux, FreeBSD, and Windows.
Responsibilities
Design and implement robust, high-performance, and scalable Ethernet device drivers for new and existing NIC hardware platforms.
Adapt, port, and maintain driver codebases across Linux, FreeBSD, and Windows operating system kernels, ensuring feature parity and optimal performance.
Analyze network latency, throughput, and CPU utilization; implement advanced techniques such as interrupt mitigation, DMA optimization, and ring buffer management to maximize NIC performance.
Utilize kernel debugging tools (e.g., KDB, WinDbg, crash dump analysis) to identify and resolve complex, asynchronous, and intermittent hardware/software integration issues.
Work directly with hardware specifications to program low-level functions including Memory-Mapped I/O (MMIO), Direct Memory Access (DMA), and Interrupt Request (IRQ) handling.
Create and maintain detailed technical specifications, design documents, and release notes for all developed drivers and kernel modules.
Required Qualifications
Education: Bachelor’s degree in Computer Science, Computer Engineering, or Electrical Engineering with 5+ years of experience OR Master’s degree with 3+ years of experience.
Expert proficiency in C with demonstrable experience in systems-level programming.
Deep understanding of operating system kernel fundamentals, including memory management, interrupt handling, concurrency, and thread scheduling.
Solid understanding of the Ethernet standard (IEEE 802.3) and network protocols (TCP/IP, UDP, ARP) up to Layer 3.
Proven experience with low-level hardware interaction, including PCI/PCIe bus architecture and register programming.
Practical experience implementing and debugging synchronization primitives such as spinlocks, mutexes, and semaphores in a kernel context.
Preferred Skills and Experience
Experience with emerging networking technologies like RDMA (RoCE, InfiniBand), DPDK, or other user-space networking frameworks.
Familiarity with network virtualization technologies such as SR-IOV, VirtIO, or other para-virtualized I/O approaches.
Experience with hardware debuggers, logic analyzers, and advanced tracing tools.
Strong proficiency with Git and associated version control workflows.
Compensation and Benefits The annual base salary range for this position is $91,000 – $146,000.
This position is also eligible for a discretionary annual bonus in accordance with relevant plan documents and equity in accordance with equity plan documents and equity award agreements.
Broadcom offers a comprehensive benefits package: medical, dental, and vision plans; 401(k) participation including company matching; Employee Stock Purchase Program (ESPP); Employee Assistance Program (EAP); company paid holidays; paid sick leave and vacation time; Paid Family Leave and other leaves of absence.
