Doug D'Souza // Senior Manager, UX Content Design // Agentic Design Lead

I design how products talk — and how AI agents think, speak, and earn trust.

UX Content Leader (ex-Meta Reality Labs, ex-Vice) leading a team of 14 building agentic AI experiences and quality systems at The Trade Desk.

My POV

"In agentic software, content design is no longer the final layer of UI polish. It is the system itself. Our job now spans how an agent takes turns, how it explains its reasoning, where its boundaries lie, and how you prove it's actually helping. What's new is designing these systems, quality bars, and trusted voice patterns inside the model loop, not just on the surface."
