Lead Engineer- L2/L3 Protocol Testing

As an experienced Network Testing Engineer, your role will involve the following responsibilities: - **Protocol Leadership:** Lead the test strategy for next-generation routing features, focusing on Segment Routing (SR) and SRv6 (Segment Routing over IPv6). - **Automation Architecture:** Design and optimize Python-based automation frameworks to validate SR/SRv6 policies, TI-LFA, and network slicing. - **Test Lifecycle Management:** Create, execute, and manage high-scale test plans for L2/L3 protocols including BGP, OSPF, IS-IS, and MPLS. - **Failure Analysis & Debugging:** Take ownership of analyzing complex failures, perform root-cause analysis (RCA) by investigating system logs, FIB/LFIB tables, and packet captures. - **Performance & Scale:** Conduct high-scale stress testing using IXIA/Spirent to validate the control plane and data plane performance of SRv6 endpoints. - **Mentorship:** Guide junior engineers in developing robust test cases and high-quality Python code. Qualifications required for this role include: - 7+ years of experience in Networking Domain testing with a focus on L2/L3 Routing. - **Protocol Mastery:** - Advanced L3 knowledge of OSPF, IS-IS, and BGP (specifically extensions for Segment Routing). - In-depth understanding of SR-MPLS and SRv6 architectures, including SIDs (uSID), LFA/TI-LFA, and Traffic Engineering (SR-TE). - **L2 Mastery:** Strong experience with VLANs, xSTP, and L2VPN/EVPN. - **Expert Python Automation:** 7+ years of experience writing production-grade Python scripts for network automation. - **Hardware Tools Proficiency:** Expert-level with IXIA (IxNetwork) or Spirent for simulating SRv6 traffic and validating scale. - **Analysis Tools Mastery:** Proficient with Wireshark for decoding SRH (Segment Routing Header) and other protocol extensions.
