Lead Performance Test Engineer

About the role

As a Lead Performance Test Engineer, you will make an impact by leading and executing performance engineering initiatives for complex enterprise and cloud-native applications. This is a hands-on technical role requiring deep expertise in performance testing, automation, cloud platforms, observability, and application resiliency.

You will collaborate with development, architecture, platform engineering, DevOps, and Site Reliability Engineering teams to establish performance standards, implement automated quality gates, identify system bottlenecks, and improve application scalability and operational readiness.

In this role, you will:

Design and execute performance, load, stress, endurance, scalability, and capacity-testing strategies for enterprise applications, APIs, and cloud-based services.

Build and maintain automated performance-testing frameworks using NeoLoad and custom performance engineering solutions.

Integrate performance testing into CI/CD pipelines using GitLab CI/CD or comparable automation platforms, including performance thresholds and quality gates.

Analyze applications, database, infrastructure, network, and cloud performance to identify bottlenecks and provide actionable optimization recommendations.

Use AWS services and observability platforms such as CloudWatch, Dynatrace, Splunk, Grafana, and Prometheus to troubleshoot complex performance issues.

Plan and execute Chaos Engineering and resiliency-testing exercises to evaluate fault tolerance, recovery capabilities, and operational readiness.

Develop automation utilities using Python, Java, SQL, APIs, and scripting languages to improve testing efficiency and reduce manual effort.

Partner with technical and business stakeholders to define performance KPIs, engineering standards, capacity requirements, and performance-improvement plans.
