Indexed description

We are looking for a talented and motivated Software Engineer with a Network/SDWAN Development focus to join our growing team. In this role, you will design, develop, and optimize software solutions that power our SD-WAN platform and network infrastructure. You will work closely with network architects, product managers, and fellow engineers to deliver scalable, reliable, and high-performance networking software.


Responsibilities

  • Design, develop, and maintain software components for SD-WAN platforms, network control planes, and data planes
  • Build and extend network management, orchestration, and automation systems
  • Implement and optimize network protocols (BGP, OSPF, MPLS, VxLAN, IPSec, etc.) within software-defined environments
  • Develop and maintain Linux-based network applications, daemons, and kernel-level networking components
  • Write high-quality, testable code in Python, Go, C, or C++ for network-facing services
  • Collaborate on the design of RESTful APIs and gRPC services for network telemetry and device management
  • Debug and resolve complex network and software issues across distributed systems
  • Participate in architecture reviews, code reviews, and technical design discussions
  • Contribute to CI/CD pipelines and infrastructure-as-code practices
  • Work with cloud platforms (AWS, Azure, GCP) for cloud-hosted SD-WAN deployments


    • Qualifications

    • 5+ years of professional software development experience
    • Deep knowledge of Linux internals — networking stack, kernel modules, namespaces, cgroups, and system administration
    • Strong understanding of networking fundamentals: TCP/IP, UDP, DNS, DHCP, NAT, firewalling, VLANs
    • Solid grasp of routing concepts and protocols: BGP, OSPF, ECMP, route redistribution, policy-based routing
    • Hands-on experience with SD-WAN technologies — overlay/underlay architectures, WAN optimization, traffic steering, zero-touch provisioning
    • Proficiency in one or more languages: Python, Go, C, or C++
    • Experience with VPN technologies: IPSec, GRE, SSL/TLS tunneling
    • Familiarity with NFV/SDN concepts: OpenFlow, DPDK, VPP, or similar data plane acceleration frameworks
    • Strong debugging skills using tools such as tcpdump, Wireshark, iproute2, eBPF/BPF
    • Experience writing and reviewing RESTful APIs and working with API-driven infrastructure


    Preferred Qualifications
    • Experience with SD-WAN vendor platforms (Cisco Viptela, VMware VeloCloud, Palo Alto Prisma, Fortinet, etc.) or open-source alternatives (OpenWRT, VyOS, pfSense)
    • Familiarity with cloud networking concepts: VPCs, transit gateways, cloud-native firewalls, direct connect
    • Experience with container networking (Kubernetes CNI, Calico, Cilium) and microservices architectures
    • Knowledge of gRPC, Protobuf, NETCONF/YANG, or OpenConfig for network device management
    • Experience with observability tools: Prometheus, Grafana, ELK stack, or similar for network telemetry
    • Background in network security: Zero Trust, SASE, firewall policy management
    • Contributions to open-source networking projects (FRRouting, Bird, DPDK, etc.)
    • Relevant certifications: CCNA/CCNP, JNCIA/JNCIP, or equivalent
