Senior Principal Engineer

You will define and drive the technical strategy for the entire Applications Portfolio, spanning Web, Mobile, and Headless surfaces. You will set frontend architecture standards, mentor and coach senior engineering talent, and collaborate deeply with Product leadership to align engineering strategy with customer needs. You will spearhead the evolution from a feature factory model to a platform-driven system, modernizing API layers and integrating emerging standards like the Model Context Protocol to enable agentic workflows. You will partner with Design Systems teams on shared UI components and design tokens, reduce systemic technical risks, and raise the bar through hands-on technical reviews and prototyping.
