Role Overview

We are looking for a Senior Network Test & Automation Engineer with strong hands-on experience in enterprise routing and switching, network design validation, lab testing, and automation.

The engineer will be responsible for testing and certifying network hardware, software releases, patches, and network designs before production deployment. The role requires strong knowledge of traditional enterprise networking along with exposure to modern cloud-native networking technologies such as Kubernetes CNI, eBPF, and Cilium.

Key Responsibilities

• Design, execute, and document network lab testing and certification.
• Test and certify routers, switches, software releases, patches, SMUs, and network designs.
• Perform functional, interoperability, performance, and regression testing.
• Validate network designs across CampBranch, WAN/MAN, Data Center, and low-latency environments.
• Perform risk/CVE-based testing and support patch certification and remediation validation.
• Troubleshoot routing, switching, performance, compatibility, and hardware/software issues.
• Build and improve automated network testing using Python and Ansible.
• Develop reusable automation workflows and improve overall test coverage.
• Work with Kubernetes networking/CNI and support validation of cloud-native network architectures.
• Utilize eBPF/Cilium concepts for networking, observability, policy enforcement, BGP integration, and troubleshooting.
• Work with vendors and engineering teams on product certification, bug validation, and new technology evaluation.
• Create engineering standards, certification documents, test results, recommendations, and technical reports.
• Provide technical guidance and communicate findings to engineering teams and senior stakeholders.

Mandatory Technical Skills

• 8+ years of Network Engineering experience.
• Strong hands-on experience with IP Routing and Switching.
• Strong knowledge of BGP, OSPF, IGMP, PIM and Layer 2 protocols.
• Hands-on experience with Cisco Catalyst/Nexus and/or Arista platforms.
• Experience with network design, testing, certification, and troubleshooting in a LAB environment.
• Strong understanding of Linux administration and networking.
• Hands-on knowledge of Python and Ansible for network automation.
• Experience with Git/GitHub.
• Good troubleshooting knowledge using tcpdump and Wireshark.
• Understanding of Kubernetes architecture and container networking/CNI.
• Exposure to eBPF-based networking; Cilium experience is highly preferred.
• Ability to independently perform complex network testing and certification.

Preferred Skills

• Experience with IXIA and/or Spirent network testing tools.
• Experience with Robot Framework and integration with Ansible.
• Cisco IOS/IOS-XE/NX-OS software/code certification experience.
• Arista 7280/7504/7060 or similar platform experience.
• Network security knowledge including 802.1X, NAC, IPSec, QoS and DDoS mitigation.
• CVE analysis, vulnerability assessment, patch testing, and remediation validation.
• AWS or Azure networking exposure.
• Data Center networking and high-speed connectivity exposure including 10G/25G/40G/50G/100G.
• CCNP-level knowledge required; CCIE is highly desirable.
•
