Lead Engineer Testing

ADTRAN is seeking a Lead Engineer in Testing to join their expanding team in Bangalore, India. This full-time role involves comprehensive testing of L2/L3 networking protocols, broadband access technologies, and implementing AI/Generative AI tools in QA. The engineer will also develop and optimize Jenkins-based CI/CD pipelines, prepare test plans, analyze defects, and collaborate with cross-functional teams to ensure high-quality releases. Mentoring junior team members is also a key aspect of this role.

Must Have

• Perform functional, regression, and performance testing for L2/L3 networking protocols (VLAN, STP, PPPoE, DHCP, IPv4/IPv6 Routing, QoS, multicast).
• Validate broadband access technologies including DSL, GPON/FTTH, ONT/OLT interactions, service provisioning, TR-069.
• Develop, maintain, and optimize Jenkins-based CI/CD pipelines.
• Integrate test automation frameworks and scripting tools (Python, Robot Framework, Shell scripts).
• Utilize AI-based QA tools for log analysis, defect prediction, and intelligent test case selection.
• Implement or integrate Generative AI tools for creating test scenarios and documentation.
• Prepare detailed test plans, strategies, and traceability matrices.
• Analyze defects, perform Root Cause Analysis (RCA).
• 7-10 years of experience in networking or telecommunications testing.
• Strong hands-on expertise in L2/L3 protocols and networking fundamentals.
• Good understanding of DSL/GPON/FTTx technologies.
• Proficiency in Jenkins CI/CD pipelines and Groovy scripting.
• Working knowledge of Python / Shell / Robot Framework for test automation.
• Experience with AI-based QA tools or applying generative AI to testing workflows.
• Familiarity with Git.
• Strong analytical and debugging skills (Wireshark/packet captures/logs).

Good to Have

• Exposure to containerized test environments (Docker, Kubernetes).
• Experience with cloud-based CI/CD and artifact management platforms.
• Understanding of OLT/ONT management systems, TR-369/USP, or BBF standards.
• Knowledge of test data analytics, ML-based insights, or automation frameworks.
