**About the Role** Delivery Marketplace is a central pillar to Uber's delivery products. As the central brain of the company, we are the decision makers that make moving from point A to point B possible for every order that Uber serves, from UberEats to new verticals such as Grocery. We handle all the logic from making the dispatch decisions, predicting how long a delivery might take, and estimating optimal pickup times for orders. We build products that directly impact Uber's top and bottom lines. Optimization Engineers lead efforts within the team and broader Delivery Marketplace organization to drive ideation, development and productionization of optimization solutions with real-time and ML-based signals that solve strategically important problems. Some existing problem spaces that the team works on: + Using statistical/machine learning/forecasting models for demand and supply models + Develop the objective function which balances magical user experience and economics of the business + Design dispatch timing algorithms It is a challenging yet rewarding job. You will have a lot of opportunities to work with product managers, data scientists and engineers from other teams. You will be in charge of solving Uber-scale problems with the right techniques like reinforcement learning, deep learning, and optimization methods. **What You Will Do** + You will build new scalable algorithms for real-time delivery matching products across hundreds of global marketplaces. + You will take things from mathematical formulation through to prototype and experiment to production. + You will help identify new opportunities for improving our algorithms and models. **Basic Qualifications** + PhD in Computer Science, Engineering, Mathematics or a related field + Experience in programming with a language such as Python, C, C++, Java, or Go. + Experience with SQL and database systems such as Hive, Kafka, and Cassandra. + 1 year or more of industry experience developing algorithms and optimization models for large-scale deployment. **Preferred Qualifications** + Experience with two or three-sided marketplace design, matching/allocation, pricing optimization, etc + Familiarity with Machine Learning models, experimentation (e.g., A/B testing) and causal inference + Experience with real-time optimization systems (optimization under tight time constraints) + Strong communication skills and ability to work effectively with cross-functional partners.
