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**-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-from idea inception and stakeholder tension to productionization and operations.**
Unblock and Multiply:** Act as a force multiplier by identifying architectural gaps and reducing technical debt across multiple organizations, ensuring systems are designed to be extensible and modular.**
Lead Through Influence:** Build strategic relationships across Product, Data Science, and Operations to ship practical solutions at speed, navigating competing priorities and influencing without control.**
Uphold the Bar:** Champion engineering excellence by role-modeling code health, testing, and design clarity, even when the pace is fast and the pressure is high.**
Mentor and Rally:** Inspire and coach the next generation of Uber's technical leaders, fostering an inclusive culture where diverse perspectives are leveraged to solve our hardest problems.**
