Design and implement comprehensive test strategies and plans for applications hosted on Azure, AWS, and GCP, covering functional, integration, performance, and security aspects. Collaborate with solution architects and development teams to review cloud architectures and identify testability, reliability, and scalability risks early in the lifecycle. Build and maintain automated test suites for cloud services, APIs, and microservices, integrating them into CI/CD pipelines for continuous validation. Validate infrastructure-as-code (IaC) deployments and environment configurations across multiple cloud platforms to ensure consistency and compliance with standards. Perform end-to-end testing of cloud migrations, upgrades, and multi-region deployments, ensuring minimal downtime and data integrity. Conduct performance, load, and stress testing of cloud-hosted applications, analyze bottlenecks, and work with teams to optimize resource utilization and cost. Execute security and compliance-related test scenarios in collaboration with security teams, focusing on identity, access, encryption, and network controls in the cloud. Troubleshoot complex issues across environments, using cloud monitoring and logging tools to identify root causes and drive resolution. Provide consulting and best-practice guidance on cloud testing approaches, tools, and frameworks to project teams and stakeholders. Prepare clear test documentation, including test cases, reports, defect logs, and recommendations, and present findings to technical and business stakeholders. Mentor junior team members on cloud testing concepts, tools, and methodologies, fostering a culture of quality and continuous improvement.
