MAIN PURPOSE
The Global Messaging Architect exists to design and govern TKO’s enterprise-wide messaging and collaboration ecosystem. This role ensures that email, calendaring, and security platforms are reliable, secure, and scalable across all global brands, while enabling seamless collaboration for employees, partners, and talent.

WHY JOIN TKO?
TKO unites three of the most recognizable brands in global sports — UFC, WWE, and PBR — with the premier hospitality brand, OLE, and the world-class broadcast, sports, and events company, IMG, to form a next-generation technology, sports, and entertainment powerhouse.
