Principal Engineer, Safety - Core Services Engineering

Principal Engineer, Safety - Core Services Engineering Department: Safety, Security & Insurance Team: Safety, Security & Insurance Location: Sao Paulo, Brazil Type: Full-Time **About the Role** 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**](https://jobs.uber.com/en/locations/sao-paulo/) —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. **What You’ll Do** **Architect for the Real World:** Design and maintain systems within Safety, Identity, and Risk that support millions of daily movements, where performance, safety, and scale can’t be separated. **Navigate Massive Complexity:** Foresee architectural problems and opportunities 1–2 years out, making intelligent bets on high-impact innovations and knowing when to "fail fast." **Drive Strategic Impact:** Lead org-wide engineering projects through every messy stage—fr
