You will play a critical role in designing, implementing, and maintaining performance testing frameworks that validate the scalability, resilience, and reliability of our microservices and cloud-native applications.

This position requires hands-on experience with Gatling, Java, Docker, and Kubernetes, as well as deep technical knowledge of backend architecture, APIs, and cloud platforms like AWS and GCP.

Backend Infrastructure Mastery :

- Gain deep understanding of APIs, backend services, databases, and cloud ecosystems (AWS, GCP) to build tests that reflect real-world usage and scenarios.

Environment Setup & Scaling :

- Build and manage performance test environments using Docker and Kubernetes, configuring Horizontal Pod Autoscaling (HPA) and other scaling strategies to validate service elasticity.

Monitoring & Analysis :

- Monitor system performance, analyze test results, and identify bottlenecks using appropriate metrics and tools. Collaborate with Engineering and DevOps to fine-tune infrastructure for optimal performance.

Cross-Functional Collaboration :

- Work closely with SREs, Backend Engineers, QA, and DevOps to proactively resolve performance issues and support capacity planning initiatives.

Reporting & Documentation :

- Create detailed test reports, documentation, and dashboards that provide actionable insights for both technical and non-technical stakeholders.
