Build and integrate AI-native capabilities using Amazon Bedrock and AgentCore Runtime, with end-to-end troubleshooting across mobile, backend, cloud infrastructure, and AI runtime layers.
This role will focus on rapid POCs and prototyping, working closely with engineers from an acquired startup and provide broad access to AWS Cloud and AI environments for hands-on experimentation.
