You will work hands-on with DWDM, ROADM, OTN equipment, EDFA and Raman amplifiers, OSC, WSS, OCM, and OTDR, configuring and validating complex optical topologies. The position involves regular use of management and control interfaces such as Netconf, YANG, Restconf, REST APIs, gRPC, SNMP, and CLI to interact with network elements. You will use Python for automation, Git and GitLab for version control and test repository management, and CI/CD pipelines to run automated test suites. Jira and Agile practices support day-to-day collaboration, defect tracking, and sprint-based planning. Work includes onsite testing activities in a Horsham lab environment, where you will participate in customer use-case validation, demonstrations, and pre-shipment testing. The environment emphasizes collaboration, technical excellence, and continuous improvement in verification processes and automation capabilities.

• At least 8 years of experience in System Verification or Test Engineering, with a focus on complex systems.
• Proven optical networking experience with DWDM systems, ROADM architectures, and OTN transport technologies.
• Demonstrated ability to create test plans and detailed test cases directly from product requirements.
• Strong in system-level validation, including black-box testing of integrated platforms.
• Solid understanding of networking protocols such as OSPF, BGP, and TCP/IP, and their application in optical networks.
• Hands-on Python automation experience, including developing scripts for test execution and validation.
• Experience using Git and GitLab for version control and management of test repositories.
• Experience working with CI/CD pipelines for automated test execution and integration.
• Ability to work effectively in an optical lab environment, including handling optical equipment and test setups.
• Strong troubleshooting and debugging skills for diagnosing complex system, software, and network issues.
• Willingness and ability to support onsite testing activities in Horsham as required.
• Hands-on experience with DWDM systems, ROADM, OTN, EDFA amplifiers, Raman amplifiers, OSC, WSS, OCM, and OTDR.
• Strong understanding of Ethernet networking fundamentals.
• Experience with management and control interfaces such as Netconf, YANG, Restconf, REST APIs, gRPC, SNMP, and CLI interfaces.
• Proficiency with Jira or similar tools for defect tracking and test management.
• Familiarity with Agile methodologies and working in an iterative, collaborative development environment., * Experience with network controller integration and YANG modeling for optical or transport networks.
• Exposure to SNMP automation for monitoring and control of network elements.
• Experience in SDN controller testing and validation of controller-based architectures.
• Experience in telecom equipment verification, particularly optical transport platforms.
• Previous involvement in customer acceptance testing, including execution of customer-specific test plans.
• Industry experience with optical transport vendors or similar network equipment providers.
• Experience enhancing or developing test automation frameworks for large-scale system verification.
• Prior leadership experience mentoring junior engineers and driving process improvements in verification teams., Individual compensation offered for this position within this range will depend on many factors, including qualifications, skills, relevant experience, job knowledge, geographic location, internal equity, and other pertinent job-related factors.
