Senior Performance Test Engineer

Performance Test Engineer

Job Description: We are seeking a skilled Performance Test Engineer to join our quality assurance team, specializing in designing, executing, and analyzing performance tests for our web applications and APIs using industry-leading tools like JMeter. You will play a critical role in identifying performance bottlenecks, optimizing system architecture, and ensuring a seamless user experience by leveraging your expertise in monitoring tools, profiling techniques, and scripting.

Responsibilities:

• Performance Test Design and Execution:
  • Collaborate with development teams to understand system architecture and identify key performance metrics.
  • Develop comprehensive performance test plans and scenarios to simulate real-world user loads.
  • Create and maintain robust JMeter test scripts, including intricate use of samplers, listeners, assertions, and thread groups.
  • Execute performance tests on various environments (staging, production-like) and monitor test execution in real-time.
  • Analyze test results to identify performance bottlenecks and critical areas for optimization.
• Monitoring and Profiling:
  • Utilize monitoring tools (e.g., Dynatrace, New Relic) to capture detailed performance metrics like response times, throughput, CPU utilization, and memory usage.
  • Implement profiling techniques to pinpoint code sections with performance issues and suggest optimization strategies.
  • Analyze server-side logs and database performance to identify potential bottlenecks.
• Script Development and Debugging:
  • Write clean, modular, and reusable JMeter test scripts with advanced scripting capabilities (e.g., JSR223, Beanshell) to handle complex scenarios.
  • Effectively debug and troubleshoot test scripts to address errors and unexpected behaviors during test execution.
• Reporting and Communication:
  • Prepare comprehensive performance test reports with detailed analysis, charts, and recommendations for improvement.
  • Communicate performance test findings clearly to development teams, stakeholders, and project managers.
  • Proactively identify potential performance risks and propose mitigation strategies.

Required Skills and Experience:

• Strong Expertise in JMeter: Deep understanding of JMeter functionalities, including test plan design, samplers, listeners, assertions, and scripting.
• Performance Testing Concepts: Thorough knowledge of performance testing methodologies, metrics (response time, throughput, concurrency), and best practices.
• Monitoring and Profiling Tools: Familiarity with application performance monitoring tools (APM) like Dynatrace, New Relic, or similar.
• Coding Skills: Basic coding proficiency in Java or other scripting languages for advanced JMeter scripting and custom development.
• Analytical Skills: Ability to analyze complex performance data, identify trends, and draw meaningful conclusions.
• Communication Skills: Excellent communication skills to effectively convey technical findings to both technical and non-technical audiences.

Desired Qualifications:

• Experience with cloud-based performance testing platforms (e.g., AWS Load Testing, Azure Load Testing)
• Knowledge of performance optimization techniques for web applications and databases.
• Understanding of distributed systems and microservices architecture.
• Experience with CI/CD integration for automated performance testing.
