Senior Staff Machine Learning Engineer - Driver Pricing & Marketplace Optimization

About the Role

We're seeking an exceptional Senior Staff ML Engineer to lead breakthrough ML innovation in Uber's Driver Pricing organization. This is a high-impact role where you'll architect and build next-generation ML systems that directly optimize marketplace efficiency and driver earnings for millions of drivers globally.

You'll tackle some of the most complex problems in applied machine learning: real-time pricing optimization, supply-demand balancing, and driver behavior modeling at unprecedented scale. Your work will involve cutting-edge techniques including causal inference, reinforcement learning, algorithmic game theory, and multi-objective optimization to solve challenges that don't exist anywhere else in the industry.

As a Senior Staff ML Engineer reporting directly to the Engineering Director, you'll drive technical strategy, mentor senior engineers, and establish ML engineering excellence across the Driver Pricing organization while solving problems that directly impact tens of billions of dollars in marketplace transactions.
