Senior Golang Architect - CRM Platform Ecosystem

On behalf of a major international partner we are looking for a Senior Architect to lead the evolution of their CRM Platform Ecosystem into a scalable, modular, API-first environment that enables dynamic customer workflows, seamless integrations, and advanced analytics capabilities.
