Were building next-gen network security tools at the edge and are urgently seeking engineers who understand ISP-grade architectures to integrate high-performance DDoS mitigation with carrier infrastructure. If you can map eBPF/XDP programs to real ISP PoPs and router configs,

apply nowimmediate onboarding for the right candidate.

What were looking for:

• Expert-level C/C++ programming for performance-critical systems, including kernelmodules and packet processing at Mpps scale.
• Deep knowledge of ISP network architecture: upstream peering via BGP (full route tables,route filtering, communities, traffic engineering with MED/AS_PATH prepending),core/edge routers (Cisco/Juniper/Nokia), aggregation layers with OSPF/IS-IS for IGP, andaccess via OLT/GPON for FTTH or BRAS/BNG for PPPoE sessions.
• Hands-on with router internals

  :

  configuring BGP neighbors (eBGP/iBGP peering sessions,prefix-limits, dampening), QoS policies (CBWFQ, LLQ for VoIP/prioritization), ACLs/iACLs for DDoS blackholing, NetFlow/sFlow export for telemetry, and VRRP/HSRP for redundancy.
• Strong experience in ability to deploy in-line on edge routers or out-of-path scrubbingmimicking ISP Magic Transit flows.
• Familiarity with Linux kernel networking (ethtool tuning, RSS/XPS for multi-queue, tc qdiscfor shaping), support infra (RADIUS/AAA for subscriber auth, DHCP pools, DNS anycast),and monitoring (Prometheus, Zabbix for PoP telemetry).
• Proven skills in traffic analysis (Wireshark/tshark for PCAP forensics), multithreading (DPDK lcores, epoll for userspace), and testing DDoS vectors (SYN/UDP/ICMP floods) in isolated labs with hping3/Scapy.

Bonus: Experience with MPLS (L3VPN/VPLS for enterprise), SRv6 for segment routing, eBPF,or EVPN for data center fabrics in ISP contexts.

If youve configured production BGP routers, scripted eBPF drops for L4floods, or troubleshotISP core handoffs, share your resume today. Lets secure carrier networks together
