- Define SLAs, NFRs, success criteria, and performance acceptance thresholds
- Oversee load, stress, endurance, and volume testing activities
- Drive performance analysis, bottleneck identification, and root cause investigations
- Provide performance reports, recommendations, and risk assessments to stakeholders
- Support dual-run operations and validate performance across legacy and target platforms
- Collaborate with development, architecture, infrastructure, and business teams
- Embed performance testing within Agile and DevOps delivery practices
- Lead performance sign-off activities and support go-live readiness decisions
