Senior Network Infrastructure Engineer: Scale & Performance

Kindredventures; United States; On-site; USD 180,000 - 240,000; Full time

Job summary

fal is the generative media ecosystem powering the next generation of AI products. We build the infrastructure, tools, and model access that teams need to move from idea to production, and do it at scale without compromise.

You will build and operate network infrastructure across public platforms and private compute clusters, focusing on fast, reliable, and secure connectivity, with a strong emphasis on automation and observability.

Qualifications

• 5+ years building and operating production network infrastructure.
• Strong Linux networking: routing tables, policy routing, namespaces, bonding, VLANs, bridges, firewalling, NAT, conntrack.
• Deep BGP knowledge: route selection, communities, filtering, convergence, multipath, troubleshooting.
• Experience managing ASNs, public IP space, BGP announcements, IPAM, ROAs, IRR records.
• Experience designing private IPv4/IPv6 address plans and preventing cross-customer/region conflicts.
• Production VXLAN overlay network experience.
• Production IPsec, WireGuard, or Tailscale experience.
• Experience with anycast DNS and mDNS.
• Experience with private peering and cloud provider interconnects.
• Linux networking performance tuning: congestion control, queue disciplines, socket buffers, MTU, NIC offloads, RSS/RPS/XPS, IRQ affinity.
• Packet-level troubleshooting: iproute2, tc, ethtool, tcpdump, Wireshark, mtr.
• Ansible or equivalent network configuration automation.

Responsibilities

• Design, build, validate, and operate public and private networks across platforms.
• Use AI to automate network provisioning, configuration, validation, monitoring, and recovery.
• Manage ASNs, public IP prefixes, and private address space allocation and announcements.
• Build and operate BGP routing: route policies, communities, filtering, traffic engineering, and failover.
• Announce customer and company IP ranges from physical infrastructure and cloud environments.
• Establish private peering with customers, partners, data centers, internet exchanges, and cloud providers.
• Build private and overlay networks using VXLAN, IPsec, WireGuard, and Tailscale.
• Operate DNS networking patterns including anycast DNS and mDNS.
• Tune the Linux networking stack for high throughput, low latency, and large connection counts.
• Build network observability and diagnostics using metrics, logs, flow data, active probes, and packet captures.
• Develop reusable tooling, standards, documentation, and runbooks.
• Collaborate with customers and internal teams to translate connectivity, security, isolation, and performance requirements into sound network designs.
