Our client is moving enterprise customers off impacted Azure Communication Services (ACS) workloads, including calling/video, call automation and recording, SMS, email, chat, advanced messaging (WhatsApp), and job router, onto Microsoft first-party destinations or approved third-party platforms where 1P does not meet customer requirements. The Migration Lead will identify ACS dependencies in customer applications, determine the appropriate replacement architecture, modify or direct modification of application integrations, validate end-to-end behavior, and lead production cutover.
