Performance Test Lead

Role & responsibilities

• Strategy and Design: Design, develop, and execute comprehensive performance test strategies and plans for our entire platform, including web, mobile, and API services.
  • End-to-End Testing: Conduct in-depth performance testing across all layers: front-end (browser), RESTful APIs, middleware services, and database layers to ensure scalability and reliability. • Front-End Performance: Utilize modern tools like k6 browser to conduct browser-level load testing, measuring and analyzing key front-end metrics including Core Web Vitals (LCP, CLS, INP) to ensure a superior user experience. • Deep-Dive Analysis: Perform advanced performance diagnostics and root cause analysis. This includes evaluating thread dumps, analyzing heap dumps, and conducting CPU/memory profiling to identify code-level and architectural bottlenecks. • Observability and Monitoring: Leverage our observability stack, including Grafana and Loki, to write complex queries, analyze logs, and monitor system behavior in real-time during test execution and in production. • CI/CD Integration: Champion a "shift-left" performance culture by implementing and maintaining automated performance tests within our CI/CD pipelines (e.g., Jenkins, GitLab CI, Azure DevOps), establishing performance gates to catch regressions early. • Collaboration: Work closely with developers, architects, and DevOps engineers to provide performance-related feedback, recommend optimizations, and define non-functional requirements (NFRs). • Reporting: Create and present detailed performance reports, baselines, and analysis to technical and non-technical stakeholders, translating complex data into actionable insights.

Preferred candidate profile

• Experience: 10+ years of dedicated experience in Performance Engineering and Testing.
• It is for US shift timings 6pm to 2am IST.WFH but on demand if required needs to comes to office during morning hours.it is mostly 2-3 days/month• Technical Breadth: Proven expertise in testing complex, distributed systems, including front-end (web/mobile), APIs (RESTful services), middleware, and databases.• Modern Tooling:• Hands-on, expert-level experience with jmeter,k6, including the k6 browser module for scripting and measuring Core Web Vitals.• Proficiency in querying and analyzing logs using Grafana Loki or similar log aggregation tools (e.g., ELK Stack, Splunk).• Provide detailed performance reports and dashboards to stakeholders.• Performance Engineering Expertise:• Deep understanding of performance engineering concepts and hands-on experience with Application Performance Monitoring (APM) tools (e.g., Dynatrace, New Relic, AppDynamics).• Demonstrable ability to analyze thread dumps, heap dumps, and garbage collection (GC) logs to diagnose complex issues.• Automation and DevOps: Strong skills in integrating performance tests into CI/CD pipelines and a solid understanding of automation principles.• Scripting: Strong scripting/programming skills in a relevant language, particularly JavaScript/TypeScript (for k6), with additional experience in Java, Python, or Go being a plus.
