Staff Software engineer - Authentication and Security Observability

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.
