• Deep expertise with k6 is preferred; experience with Locust, Gatling, or similar frameworks is required.
• Experience performing large-scale distributed load generation.
• Strong understanding of performance engineering principles including scalability, resiliency, throughput, latency analysis, and bottleneck identification.
• Hands-on experience with modern observability tooling including Grafana, Prometheus, Datadog, OpenTelemetry, distributed tracing, and APM platforms.
• Experience working with cloud-native, microservices-based, event-driven architectures.
• Proven ability to identify, analyze, and remediate complex performance issues across application, messaging, database, and infrastructure layers.

Technical Skills:

• 7+ years of Infrastructure, Platform Engineering, DevOps, or Site Reliability Engineering experience.
• Strong hands-on experience supporting performance and load testing environments.
• Deep expertise in Google Cloud Platform (Eligible to workP) and Kubernetes (GKE).
• Experience building and managing distributed load testing infrastructure.
• Hands-on knowledge of k6, Locust, Gatling, and distributed test execution platforms.
• Strong understanding of cloud-native architectures, containerization, and microservices.
• Expertise with Infrastructure as Code using Terraform or similar tools.
• Experience provisioning and managing scalable test environments and automated data seeding solutions.
• Advanced knowledge of observability platforms including Grafana, Prometheus, Datadog, OpenTelemetry, distributed tracing, and APM tools.
• Strong Linux administration and infrastructure automation skills.
• Experience with CI/CD pipelines and automated test orchestration.

Functional Skills:

• Infrastructure scalability and reliability planning.
• Performance engineering support and optimization.
• Capacity planning and resource management.
• Infrastructure troubleshooting and root cause analysis.
• Automation-first mindset.
• Cross-functional collaboration and technical leadership.
• Strong communication and stakeholder management skills.

Roles & Responsibilities:

• Design, provision, and maintain production-like performance testing environments in Eligible to workP.
• Build and manage Kubernetes-based infrastructure supporting large-scale distributed load testing.
• Configure and optimize distributed load generation frameworks and execution environments.
• Automate environment provisioning, configuration, test execution, and teardown processes.
• Develop and maintain test data generation and seeding strategies.
• Implement and manage observability solutions to monitor platform behavior during performance tests.
• Support performance test execution and troubleshooting across engineering teams.
• Monitor system health, infrastructure utilization, and scalability metrics during testing activities.
