Role Description: Hands-on QA Engineer covering both functional testing and automation, with ownership of the AWS-hosted regression framework and process — engineering fixes at framework and infrastructure level, not just running tests and analysing results. Own the AWS automation framework — permanently fix cloud failure modes (container restarts, load balancer timeouts, DB connectivity and connection-pool exhaustion, S3/SQS integration, IAM/credential expiry, config drift) rather than re-running or masking them.
