This is not a generic AWS or Jenkins role. You must have hands-on experience with Amazon internal tools (Brazil, Apollo, Pipelines, Coral) and be able to enable microservices for Model Context Protocol (MCP) on Ada Agent and Quick Suite. What You'll Do: * Provision test accounts, access, and environments on native builder systems. * Design, write, and run integration and load tests in Amazon Pipelines. * Refactor and expose microservice APIs so they are MCP-ready (metadata, fields, tool names). * Enable and register MCP endpoints in Ada Agent and Quick Suite; author AgentCards. * Support deployments via Brazil version sets and keep pipelines healthy. * Remediate Policy Engine and SAS security and policy findings. * Handle manual deploys, minor defects, and low-severity operational tickets.
