## About the Role

* Hands-on systems programming experience in C or C++.
 * Strong operating systems fundamentals (scheduling, memory management, I/O) - you must be able to articulate in extreme detail how a computer works, from the hardware all the way up to high-level applications.
 * Understanding of computer networking, both in the host (OS stack) as well as common network devices like switches and routers.
 * Excellent written and verbal communication skills.

PREFERRED SKILLS AND EXPERIENCE:

 * Deep knowledge of the Linux kernel and its networking stack - transferable experience with another production-grade kernel is okay, too!
 * Proficiency with debugging tools spanning kernel, network, and userspace (e.g., ftrace, perf, Wireshark/tcpdump, eBPF, gdb, and more).
 * Experience bringing up new hardware from scratch - you have flashed bare-metal software on a microcontroller with JTAG, or bootstrapped a Linux kernel and rootfs on new hardware.
 * Demonstrated track record of developing and optimizing device/peripheral drivers - ideally for high-speed interfaces, or with advanced considerations like DMA and cache coherency.
 * Understanding of major peripheral hardware interface standards (Ethernet, PCIe, I2C, SPI, etc.) - you can critically review a schematic, and debug these interfaces if needed.
 * Experience with product security, OS/system hardening, and secure boot schemes.
