Responsibilities

- Design comprehensive performance test strategies that align with business goals to ensure applications meet scalability and reliability expectations in production environments.
- Develop detailed performance test scripts using Apache Jmeter and Loadrunner to simulate real world user behavior across critical business workflows.
- Execute performance load stress and endurance tests for REST Web Services and microservices to validate response times throughput and system stability.
- Analyze performance metrics from servers databases and networks using PerfMon and related tools to identify resource bottlenecks and tuning opportunities.
- Create reusable Python utilities and automation frameworks to streamline performance test execution data preparation and result validation.
- Validate and monitor REST API performance by designing robust test scenarios that cover functional flows error conditions and security constraints.
- Investigate performance issues by correlating application logs Splunk dashboards and infrastructure metrics to determine root cause and remediation steps.
- Configure and maintain Docker environments to provision repeatable and isolated performance test setups that mirror production like conditions.
- Integrate performance tests into Jenkins CI pipelines to enable continuous performance validation with each build and deployment cycle.
- Build intuitive Grafana dashboards to visualize key performance indicators enabling stakeholders to track system health and capacity trends over time.




- Utilize Fiddler and similar tools to capture and analyze HTTP traffic ensuring accurate test scripting protocol handling and defect triage.
- Apply information security awareness and software security principles to design performance tests that respect data protection requirements and secure coding practices.
- Collaborate closely with developers architects and operations teams to review test findings recommend tuning actions and validate performance improvements.
- Document performance baselines test approaches results and lessons learned in a clear and reusable format to support future releases and audits.
- Follow secure practices aligned to OWASP Top Ten to ensure that performance testing does not introduce vulnerabilities and that nonfunctional risks are managed.
- Support defect management by providing detailed evidence metrics and reproduction steps to accelerate resolution of performance related issues.
- Contribute to continuous improvement initiatives that enhance performance testing coverage automation observability and reporting maturity.
- Mentor peers on performance testing best practices tooling usage and interpretation of performance metrics to uplift overall team capabilities.
- Engage in regular review sessions with product and business stakeholders to explain performance behaviors risks and tradeoffs in understandable terms.
- Ensure that all test activities align with corporate information security standards and regulatory expectations reinforcing trust in delivered solutions.
- Drive proactive capacity planning by using historical performance trends and forecasts to help teams plan scaling strategies and infrastructure investments.




- Support integration of Selenium Python scripts where needed to align functional automation with performance scenarios for end to end validation.
- Maintain high quality documentation for test environments configurations and data sets to ensure reproducibility and compliance with internal controls.
- Participate in hybrid collaboration routines including onsite and remote ceremonies to ensure alignment across distributed delivery teams.
