Who We Are:

DEPARTMENT: TKO IT Infrastructure

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. At its core, the role provides architectural leadership across M&A, divestiture, and brand migration programs, safeguarding business continuity, regulatory compliance, and executive communications. This is a pivotal position at the intersection of technology strategy, cybersecurity, and enterprise collaboration, directly influencing the experience of every TKO employee worldwide.

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. As TKO prepares to separate from Endeavor and build a fresh infrastructure, this is a rare opportunity to engineer core systems at scale in a greenfield environment.

You’ll work with cutting-edge identity, cloud, and infrastructure technologies from Okta and Entra ID and enterprise automation using Workato, Service Now, Workday, and Okta Workflows. The challenges are complex, the expectations are high, and the impact is real. Your work will support everything from corporate operations to global broadcasts and live events.

If you want to build something that lasts and do it with autonomy and purpose, then TKO is where you want to be.
