Lead Infrastructure Engineer - Microsoft 365 Office Client Engineer

In the Microsoft 365 Office Client Engineering space, you own the packaging, validation, and release execution for Office client software across a global virtual and physical desktop estate. You are accountable for getting validated updates and new capabilities onto the desktop safely, at scale, and on a predictable schedule. This is a hands-on engineering role with release accountability. You will build the test and deployment pipeline that turns a multi-week manual cycle into a repeatable run, define the ring strategy and go/no-go criteria that protect line-of-business add-ins and macros, and act as the technical escalation point with Microsoft. The environment is heavily customized and tightly controlled, so speed has to be earned through automation, evidence, and a rollback path that works.
