Assist development engineers in product defect diagnosis/debugging and verification of fixes.
• Day-to-day activities include planning, designing, automating, and validating tests around scale, performance, longevity and robustness tests across all supported features or feature combinations (Uni-D and Multi-D) to validate system behaviours at limit and endurance. Develop test-plans, plan and design test-topologies and test methodologies with optimal resource usage.
• Prepare/Automate robust, quality, S&P scripts with robustness and longevity also in perspective with optimal CPU and memory measurement reading mechanisms, and feature/systemic performance measurement mechanisms. 
• Use JIRA to file defects following proper template, and all logs/debug command output/traffic flow footprint, etc.  relevant to the problem description.
• Assist development engineers in product defect diagnosis/debugging/reproduction and verification of fixes.
• Execution of test cases and reporting test results with artifacts using Test Rail
• Work closely with engineers across teams/geographies to ensure quality for the features.
• Position requires troubleshooting and problem-solving skills
