Network Operations Engineer III

Summary

We are seeking a highly skilled and experienced Lab Network Engineer to design, implement, and manage our end-to-end network testbeds. You will play a critical role in supporting our lab teams by building, maintaining, and reconfiguring lab equipment to meet their specific testing needs. This role requires a strong understanding of IP networking, routing & switching protocols, and the ability to develop test automation scripts.

Responsibilities

• Design, implement, and deploy end-to-end lab testbeds based on provided requirements.

• Provide qualified network engineering support for installation and decommissioning of cabinets and network equipment.

• Verify and troubleshoot connectivity and health of network devices within the testbeds.

• Build, maintain, and reconfigure lab equipment to meet the specific needs of the lab teams.

• Develop test automation scripts, troubleshoot network protocols, testbeds, and execute test campaigns.

• Configure IPv4/IPv6/Ethernet networking for various testbed elements such as mobile devices, switches, routers, wireless/cellular equipment, servers, including ports, firewalls, ACLs, and NAT rules.

• Configure Linux-based systems (servers, compute, databases) that are part of the testbeds, and ensure proper network interconnectivity with enterprise systems, production systems, and internet access. 

• Develop test scripts to extract network metrics from devices, protocols, and databases through API queries, WebSocket interfaces, and Android debugging tools (adb).

• Assist in maintaining additional lab infrastructure such as compute and storage systems, monitoring systems, and test equipment.

• Analyze and compare test results from test campaigns and prepare comprehensive reports in a presentable format.

Recommended Qualifications

• Subject matter expertise in IP Networking/Routing & Switching (TCP/IP, IPv4/v6, BGP, ISIS, OSPF, and/or MPLS). Network certifications such as CCNA/CCNP, JNCIA/JNCIS, RHCSA, or equivalent experience are highly preferred.

• Experience with 100G/400G Ethernet and CWDM, DWDM, and optical transport network technologies. Experience configuring and troubleshooting routing and switching protocols (BGP, IS-IS, MPLS, RSVP-TE, VRRP) is a plus.

• Proven ability to analyze complex situations, troubleshoot and root cause system issues, and solve problems efficiently.

• Experience working in data centers, colocation facilities, internet exchanges, or central offices. Working knowledge of physical network infrastructure, including power, cooling, structured cabling, and fiber-optic cabling, is a plus.

• Experience working in a multi-vendor environment with hands-on experience with networking hardware.

• Familiarity with Linux-based systems and experience with scripting and automation (Bash, Python, Perl) is essential.

• Bachelor's degree in Computer Science, Computer Engineering, or a relevant technical field, or equivalent practical experience.

• Work experience in designing, deploying, and operating large-scale networks.

• Experience in deploying, configuring, and troubleshooting routing and switching protocols (BGP, IS-IS, MPLS, RSVP-TE, VRRP) and Optical Transport Networks (OTN) is a plus.

• Experience with a revision control system (e.g., Git) is preferred.
