Security Engineer II - Threat Modeling & AI

Sec Eng at Uber means building for real-world impact under real-world constraints. As Uber rapidly adopts AI and agentic workflows, we must ensure this evolution is secure by design. We are looking for a hands-on Security Engineer to red team this emerging surface area, identify critical vulnerabilities across agents and tools, and drive the engineering changes necessary to mitigate them. This role isn't just about finding bugs; it’s about navigating the messy reality of high-stakes, fast-moving AI adoption. You will need to move from deep technical architectures to leadership-level risk discussions, often pushing back on designs with imperfect information. If you are a resilient problem-solver who enjoys unblocking teams while maintaining a high security bar, you will thrive here.
