• Strategic and Holistic Networking Product Validation Lead the creation of long-term, robust test strategies across AWAN platforms, ensuring the sustained quality, performance, and scalability of our networking products.
• Advanced Debugging and Issue Diagnosis Expert-level debugging skills to precisely isolate root causes of failures quickly, distinguishing between software defects, hardware anomalies, and configuration issues within complex MX, ACX, and PTX environments.
• 360-Degree Technical Assessment and Optimization Conduct thorough evaluations of regression test results for MFT, JVD, and platform-specific testing efforts, identifying opportunities to optimize test coverage, reduce operational and capital expenditures, and improve overall testing efficiency.
• End-to-End Test Workflow Ownership Across Platforms Maintain deep expertise in regression testing workflows across multiple technology levels and diverse platforms—driving alignment and consistency in testing for AWAN prodcuts.
• Resolution of Complex Testing Challenges Leverage extensive experience to resolve intricate issues in MFT/JVD regression testing pipelines, ensuring adherence to the highest standards of product quality and reliability.
• Enhanced Reporting for Regression Outcomes Innovate and restructure regression test result reporting mechanisms for MFT, JVD, and platform tests to deliver clear, comprehensive, and trustworthy insights to stakeholders and customers.
• Collaborative Analysis with Cross-Functional Teams Work closely with Development, Test, and Automation teams to analyse test coverage gaps, drive root cause analysis, and improve debugging efficiency in complex network environments.
• JUNOS/EVO Platform Expertise Utilize prior experience with JUNOS/EVO systems to inform test design, debugging, and validation efforts across AWAN platforms for MFT/JVD test cycles.
• Root Cause Analysis (RCA) and Continuous Improvement Lead RCA initiatives to identify coverage gaps within MFT and JVD regression suites, implementing corrective actions that enhance test effectiveness and product robustness.
• Leadership in Test Automation Frameworks Spearhead the design, enhancement, and scaling of automation frameworks and tools using Python, Go, and GenAI/ML technologies—accelerating regression testing cycles for MX, ACX, PTX, and related programs.
• Mentorship and Innovation Advocacy Serve as a thought leader and mentor on emerging testing technologies—including Generative AI and machine learning—fostering a culture of innovation and continuous professional growth within the test organization.
