- Experience with Linux networking internals (e.g. routing, netfilter/iptables/nftables, conntrack) in production environments. -
- experience designing, debugging, and operating distributed systems. -
- Experience with eBPF or advanced Linux kernel networking. -
- Experience developing systems in Go or similar languages that interact with low-level OS and networking primitives.
