3+ years of hands-on experience with cloud-native NGFWs and network security appliances.
5+ years of experience in Linux networking, including firewall configuration using netfilter, iptables, and nftables, as well as DNS filtering, traffic shaping, and QoS.
3+ years of experience with network security technologies including DNS filtering, Deep Packet Inspection (DPI), Intrusion Detection and Prevention Systems (IDPS), Anti-Virus, and SSL Proxy.
2+ years of experience working with SASE components such as DLP, SWG, ZTNA, CASB, sandboxing, anti-malware, and anti-virus.
2+ years of hands-on experience with Linux userspace fast-path frameworks such as VPP and DPDK

Preferred Qualifications

Hands-on experience with fast path Linux Kernel fast path technologies like eBPF, XDP, and AF_XDP.
