  • Integrate test results with observability platforms
  • Maintain and evolve LoadRunner scripts and environments
  • Document methodologies, baselines, and trend analysis
  • Mentor QE engineers on performance and failover testing techniques
  • Collaborate with development, DevOps, and infrastructure teams on requirements and capacity planning
