Set backend architecture and AI strategy for Airbnb's Messaging, notifications, and partner-connectivity platform

Airbnb is hiring a Senior Staff Engineer as a hands-on individual contributor on the Communication and Connectivity team, which owns Messaging (the 2nd most-used surface in the app), push notifications, and the platform connecting third-party partners to Airbnb. With a 12+ year bar, this role blends backend architecture ownership, applying modern AI to products and dev cycles, and cross-functional technical leadership with design, product, and data science. Expect deep systems-design and technical-leadership questions, since Airbnb explicitly expects even its most senior ICs to stay hands-on and write code.
