Software Engineer, C++ Developer

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.

• 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, Win Dbg, 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.

• 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.

• Experience with emerging networking technologies like RDMA (RoCE, Infini Band), 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.

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.
