Principal Engineer, Safety - Core Services Engineering

Being a Principal Engineer at Uber isn’t about sitting in an ivory tower; it’s about being in the trenches of the most complex technical challenges we face. At this level, your impact isn't measured by a single feature, but by the technical trajectory of entire organizations. You will lead the Safety and Core Services mission from our Sao Paulo Tech Center —a critical global hub that is expanding at a breakneck pace. Sao Paulo is at the heart of Uber’s growth strategy. It is one of our most complex and high-volume markets, making it the ultimate proving ground for safety innovations. As a Principal Engineer here, you aren't just supporting global systems; you are leveraging the unique challenges of the Latin American landscape to build platforms that protect users worldwide. This role is high-stakes and high-ambiguity. If you are a pragmatic technologist who acts as a humble teacher and cares about building things that actually work in the real world—this is where you’ll make your mark. Core Services is the foundation of Uber’s entire ecosystem. Without the systems you will lead—Safety, Identity, Risk, and Payments—the Uber app doesn't just stop working; it loses the trust of millions. Every time a rider joins the platform, a driver gets paid, or a trip is monitored for safety, they are relying on the invisible, high-scale architecture of Core Services. You are responsible for the heartbeat of the company.
