Performance Optimization Specialist

Performance Optimization Specialist

We are seeking a skilled Performance Optimization Specialist to join our team. In this role, you will be responsible for developing and executing comprehensive performance test strategies, plans, and scenarios for complex applications deployed on cloud platforms and microservices architectures.

Key Responsibilities

• Performance Test Strategy & Planning: Develop comprehensive performance test strategies, plans, and scenarios for complex applications, including those deployed on cloud platforms and microservices architectures.
• Scripting & Execution (JMeter Focus): Design, develop, and execute high-fidelity performance test scripts using JMeter, covering various protocols (HTTP/S, API, database, etc.)
• Cloud Performance Testing: Conduct performance testing of applications deployed on cloud platforms (e.g., AWS, Azure, GCP), understanding cloud-specific performance considerations like elasticity, resource utilization, and regional latency.
• Containerized Environment Testing (Docker & Kubernetes): Leverage Docker for creating isolated and consistent performance testing environments. Deploy and orchestrate JMeter tests on Kubernetes clusters for scalable and distributed load generation.
• Monitoring & Analysis: Utilize various monitoring tools (e.g., Grafana, Prometheus, ELK Stack, New Relic, Datadog) to gather and analyze system performance metrics (CPU, memory, network I/O, disk I/O, response times, throughput, error rates, etc.) during test execution.
• Bottleneck Identification & Root Cause Analysis: Analyze performance test results, identify performance bottlenecks, and perform root cause analysis of identified issues.
• Reporting & Recommendations: Generate clear, concise, and actionable performance test reports for stakeholders, including developers, architects, and product managers. Provide data-driven recommendations for performance improvements and optimizations.
• Collaboration & Communication: Collaborate closely with development, DevOps, and operations teams to integrate performance testing into the CI/CD pipeline and ensure performance considerations are embedded throughout the software development lifecycle.
• Troubleshooting: Assist development teams in debugging and resolving performance-related issues.
• Documentation & Knowledge Sharing: Maintain comprehensive documentation of test plans, scripts, results, and best practices.

• 4+ years of hands-on experience in Performance Testing.
• Expertise in performance testing tools, specifically Apache JMeter for script development and execution.
• Strong understanding and practical experience with Cloud platforms (AWS, Azure, or GCP) and their impact on application performance.
• Proficiency in using Docker for containerizing applications and test environments.
• Experience in orchestrating and managing performance tests on Kubernetes clusters.
• Demonstrated experience with performance monitoring tools and techniques.
• Solid understanding of performance testing methodologies, types (load, stress, endurance, scalability, spike), and best practices.
• Experience with scripting languages (e.g., Python, Groovy) for test automation and data manipulation is a plus.
• Knowledge of application architecture, databases, and network protocols.
• Strong analytical, problem-solving, and debugging skills.
• Excellent written and verbal communication skills, with the ability to articulate complex technical issues to both technical and non-technical audiences.
• Ability to work independently and as part of a collaborative team in an Agile/Scrum environment.

• Experience with other performance testing tools (e.g., LoadRunner, Gatling, k6).
• Familiarity with CI/CD pipelines and DevOps practices.
• Experience in performance testing microservices architectures and APIs.
• Certifications in performance testing or cloud platforms.
