Software Engineer III - Performance Engineer

Role Overview

As a Software Engineer III - Performance Engineer (Playwright, JMeter) at JPMorgan Chase within the Commercial & Investment Bank, you'll serve as a Performance Test Engineer to design, build, and execute performance and reliability testing for critical applications and services. This role blends hands-on performance engineering (load, stress, endurance, scalability) with test automation, including Playwright-based automation experience, to improve quality, resilience, and customer experience across our platforms.

Responsibilities

• Design and execute load, stress, spike, soak/endurance, and scalability tests for web applications and APIs.
• Develop and maintain performance test scripts using Apache JMeter, including parameterization, correlation, assertions, timers, and test data management.
• Execute and manage tests at scale using BlazeMeter (or comparable platform), including distributed runs, scheduling, and reporting.
• Leverage Playwright (TypeScript/JavaScript) for UI workflow automation where appropriate.
• Integrate performance and automation testing into CI/CD pipelines (e.g., Jenkins, GitHub Actions, GitLab CI, Azure DevOps).
• Maintain reusable test frameworks, utilities, and shared libraries for performance testing.
• Instrument and monitor system behavior during tests using observability stacks such as Grafana.
• Correlate performance test results with application and infrastructure metrics to diagnose bottlenecks.
• Produce performance test reports, trend analysis, capacity insights, and actionable remediation guidance.
• Leverages enterprise-authorized AI coding assist tools within the work environment to improve code quality and productivity.

Requirements

• Formal training or certification on software engineering concepts and 3+ years applied experience.
• Hands-on experience using enterprise-authorized AI-assisted software development tools.
• Practical experience with Apache JMeter for scripting and executing performance tests.
• Experience using BlazeMeter for running/managing JMeter tests.
• Experience with Grafana for visualization and monitoring of performance test runs.
• Experience in Playwright and UI automation concepts.
• Strong understanding of performance engineering concepts: response time, throughput, concurrency, latency percentiles, SLAs/SLOs.
• Proficiency in one or more languages such as JavaScript/TypeScript, Java, Python, or C#.
• Experience with metrics/logging/tracing ecosystems (e.g., Prometheus, Splunk, ELK, Dynatrace, AppDynamics).
• Experience with containerized/cloud environments (Docker, Kubernetes, cloud platforms) and database performance fundamentals.
