  • Establish and maintain private peering with customers, partners, data centers, internet exchanges, and cloud providers.
  • Build and operate private and overlay networks using technologies such as VXLAN, IPsec, WireGuard, and Tailscale.
  • Design and operate DNS networking patterns, including anycast DNS and mDNS.
  • Tune Linux networking systems for high throughput, low latency, and large connection volumes.
  • Build network observability and diagnostic capabilities using metrics, logs, flow data, active probes, packet captures, and other monitoring techniques.
  • Develop reusable networking tools, standards, documentation, operational procedures, and runbooks.
  • Collaborate with customers and internal engineering teams to translate connectivity, security, isolation, and performance requirements into scalable network architectures.
  • Identify opportunities to improve reliability, operational efficiency, automation, and network performance across the infrastructure environment.

  Requirements

  • 5+ years of experience building and operating production network infrastructure.
  • Strong expertise in Linux networking, including routing tables, policy routing, network namespaces, bonding, VLANs, bridges, firewalling, NAT, and conntrack.
  • Deep knowledge of BGP, including route selection, communities, filtering, convergence, multipath, and troubleshooting.
  • Hands-on experience managing ASNs, public IP space, BGP announcements, IPAM, RPKI/ROAs, and IRR records.
  • Experience designing private IPv4 and IPv6 address plans while preventing conflicts across customers, regions, and environments.
  • Production experience with VXLAN overlay networks.
  • Production experience with IPsec, WireGuard, or Tailscale.
  • Experience operating anycast DNS and mDNS.
  • Experience establishing private peering and integrating with cloud-provider networking and interconnect services.
  • Strong understanding of Linux network performance tuning, including congestion control, queue disciplines, socket buffers, MTU, NIC offloads, RSS/RPS/XPS, and IRQ affinity.
  • Strong packet-level troubleshooting skills using tools such as iproute2, tc, ethtool, tcpdump, Wireshark, and mtr.
  • Experience with Ansible or equivalent network configuration and infrastructure automation tools.
  • Strong problem-solving skills and the ability to independently troubleshoot complex infrastructure issues.
  • Ability to collaborate effectively with engineering teams and customers while communicating complex networking concepts clearly.
  • Experience with EVPN as a VXLAN control plane is a plus.
  • Familiarity with FRRouting, BIRD, or similar software-routing platforms is desirable.
  • Experience with AWS Direct Connect, Google Cloud Interconnect, or Azure ExpressRoute is advantageous.
  • Experience with internet exchanges, cross-connects, route servers, or colocation networking is a plus.
  • Knowledge of DDoS detection, mitigation, scrubbing, or BGP-based traffic diversion is beneficial.
  • Familiarity with eBPF, XDP, or DPDK is desirable.
  • Experience with NetBox, Nautobot, Nornir, Kubernetes networking, service load balancing, or CNI technologies is a plus.
  • Experience with network hardware from vendors such as Arista, Juniper, or Cisco is beneficial.
  • Python or Go development experience is a plus.
