     We are working with the latest technologies of modern networking. We create user-space and kernel-space drivers for advanced network equipment such as switches, routers, and smart network interface cards, such as smartNICs, IPUs, and DPUs, and integrate them with NVF and cloud-native platforms.

    What else you should know:

    • We often work using client-supplied hardware and tools
    • Our projects may be managed by our EMs or directly by the client
    • We work with clients in the US, Asia, and Europe

    • Take part in building and expanding the technical knowledge base & share the knowledge with your colleagues
    • Fix bugs efficiently and effectively and find workarounds for blockers
    • Occasionally, take part in technical pre-sales meetings
