Senior Software Engineer, Network Infrastructure

The role

You will own the networking backbone of the multi-cloud, application, and corporate infrastructure. This includes designing, building, and operating the network layer across GCP, AWS, and Azure.

What you will do

• Own the multi-cloud network foundation including VPC design, routing, transit hubs, IPAM, IPv6, and multi-region failover.
• Build hybrid and on-prem connectivity using IPsec VPN, BGP, Cloud Interconnect, Direct Connect, and ExpressRoute.
• Design the Kubernetes networking layer including CNI, ingress, service mesh, and mTLS.
• Run the edge including load balancing, DNS, WAF, DDoS mitigation, and rate limiting.
• Secure the network via firewalls, segmentation, zero-trust access, and encryption in transit.
• Own network observability using flow logs, packet capture, and eBPF visibility.
• Treat the network as code using GitOps with Argo CD.
• Debug hard problems like TCP/UDP, NAT, connection tracking, asymmetric routing, MTU, and kernel networking.

Required qualifications

• 6+ years of experience in cloud native networking or infrastructure engineering
• Deep expertise in network fundamentals: TCP/UDP/ICMP, BGP, IPsec, NAT, stateful firewalls, VLANs, bridges, TUN/TAP, and connection tracking
• Experience with public cloud networking (GCP, AWS, Azure)
• Experience with Kubernetes and cloud-native networking (CNI, eBPF, Gateway API, Envoy, Istio)
• Experience with Infrastructure-as-Code (Terraform, Pulumi)
• Experience designing and operating VPN and site-to-site connectivity at scale
• Experience with BGP route filtering, multi-path routing, and traffic engineering
• Experience with network security: firewalls, WAF, DDoS mitigation, segmentation, and zero-trust
• Experience with network observability and performance troubleshooting (flow logs, packet analysis, latency, packet loss)

Nice to have

• Experience with Cloud Interconnect (Dedicated Interconnect, Direct Connect, ExpressRoute)
• Experience with kernel network tuning and BGP route optimization
• Experience running DNS infrastructure at scale
• Experience with on-prem or hybrid environments and data center networking
• Contributions to CNCF networking projects (Cilium, Envoy, Istio)
• Experience with network automation and testing (GitOps, Batfish, containerlab)
• Experience in regulated industries with HIPAA, SOC 2, or PCI obligations
