About the Role Uber's authentication platform handles thousands of requests per second across human users and machine identities - but today, we lack a unified way to understand the risk posture of those identities and the assets they touch. That's what you'll build. Engineering at Uber means building for real-world impact under real-world constraints. The problems are complex, the systems are massive, and the pace is fast. As a Staff Engineer on the Login Services team (Core Security Engineering), you'll lead the design and delivery of a Security Observability Platform. This is a greenfield opportunity where you'll need to make smart decisions with imperfect information and own them end-to-end. If you think in systems, stay calm under pressure, and care about building high-leverage data platforms that sit at the intersection of security and infrastructure, this is where you'll grow. What You'll Do - Design, build, and maintain a Security Observability Platform-including data models, identity/asset graphs, and risk signal pipelines-where performance, safety, and scale are paramount. - Solve messy, high-impact problems at the intersection of security and infrastructure, often starting without a clear playbook or predefined solution. - Champion engineering best practices like code health, testing, and design clarity, ensuring the platform remains reliable and observable even as we scale rapidly. - Own your work end-to-end , from the initial architectural design doc to debugging production issues when the stakes for company-wide security are high. - Turn data into decisions by collaborating across Security, IT, and Ops to identify high-value use cases like adaptive auth policies and automated threat detection. - Navigate ambiguity and complexity , working through technical debt and shifting priorities while keeping long-term security impact in mind. - Lead through influence , driving technical direction, conducting design reviews, and mentoring senior engineers through hands-on collaboration rather than just oversight. Basic Qualifications - 8+ years of experience building platform services (APIs, data pipelines, or shared infrastructure) in production distributed systems. - Proficiency in Go or Java (our primary stack) with a track record of writing high-quality, reliable, and testable code. - Experience owning complex systems end-to-end , including architecture, rollout, and long-term operational health in high-uptime environments. - Experience building data platforms or graph-based systems that serve multiple internal or external consumers. Preferred Qualifications - Background in security engineering , particularly in identity, authentication, or security data/signals platforms. - Experience modeling risk , such as fraud signals, threat scoring, or compliance posture systems. - Systems thinking and adaptability , with a proven ability to align stakeholders across organizational boundaries to drive a technical vision. - Technical leadership experience , including mentoring senior engineers and setting strategic direction for a team or organization.
