The ideal candidate will have strong hands-on experience with Java/J2EE application architectures and AWS cloud services, along with a proven track record of supporting large-scale migration and modernization efforts. You will play a critical role in designing, implementing, and optimizing cloud-native solutions using microservices, containers, and serverless technologies while ensuring performance, security, and operational excellence. This is a hybrid role with 3 days in-person required in the office.
