Software Engineer [System & Data Plane]

A NauWork client is seeking a System & Data Plane Software Engineer to join their team. The position is fully remote .

This well-funded and rapidly growing startup in the hardware and software design space is working to solve the bottlenecks in the next generation of datacenter infrastructure and is founded by a team of experienced innovators.

Our client is looking for talented C and C++ software engineers with a passion for writing low-level high-performance code in the world of packet processing and datacenter networking, capable of working closely with the hardware constraints and innovative features provided by the architecture, while being capable of writing high-quality code to define the SDK and the features exposed to the customers - both in kernel and user land.

Required Experience:

• Is a skilled C or C++ coder. Can create optimized code through different levels of abstractions, can help define and guide the creation of those abstractions and APIs, complete with documentation, testing, and examples.
• Can identify bottlenecks and performance risks, can write high-efficiency code. Is familiar with common profiling tools, has some experience around writing high-performance code and avoiding some of the pitfalls and costs introduced by different layers of abstractions, has worked with benchmarks and micro benchmarks before.
• Is a strong System Software Engineer. Understands the kernel and userspace boundaries well, can use low-level syscalls to interface with the kernel, understands constraints posed by the scheduler and the virtual memory system. Does not shy away from using mmaps(), unix domain sockets, or debugging issues related to VDSO, libc interactions, and the ELF loader.
• Can write concurrent code and is comfortable working close to the hardware. Understands the memory model, barriers, lock-free data structures, atomics, and caching behavior of most popular architectures (x86, ARM), as well as some of the constraints related to MMIO, DMA, and working with hardware devices.
• Has experience writing data plane code - code in the hot path of packet processing - and has familiarity with libraries and frameworks like libibverbs, libfabric, DPDK, SPDK or eBPF and XDP. As well as frameworks like NCCL, and lower levels of pytorch and tensorflow. Not as a customer or user of those libraries/frameworks, but as someone knowledgeable of how they work, and confident in being able to modify and grow them.
• While not necessarily a linux kernel developer, can pinpoint driver interaction issues, is comfortable diving in kernel code, and could be comfortable in adding features that require writing kernel code and working closely with our kernel engineers.
