Sr Machine Learning Engineer

About the position

The coordinated structural pricing and simulator team works on setting rider and driver prices to achieve marketplace balance. We maintain many offline models to simulate and optimize marketplace price levels at a coarse granularity to achieve growth in trips and GB while maintaining marketplace reliability and VC neutrality. We are actively working on a new pricing and simulation tech called Pricer-Planner and exploring many different avenues for simulation, both ML-driven and structural economics-driven. The Uber Marketplace team is at the core of Uber's business, and Marketplace Intelligence aims to mitigate negative customer experience and perception through intelligence. The mission of the team is to foster growth and reduce user churn at Uber by pushing the frontiers of machine learning, data science and economics and developing highly reliable and scalable platforms to accelerate Uber's impact on the transportation industry. This role will drive high-impact projects to optimize consumer marketplace experiences at Uber using optimization, machine learning, and causal inference.
