Senior ML Engineer - Dynamic Pricing

**About the Role** The mission of the Surge team is to maintain overall marketplace reliability by balancing supply/demand in real-time through dynamic pricing. We build scalable real-time systems to understand the state of the market, forecast future demand, make predictions using ML models, solve network optimization programs, and eventually make pricing decisions for each rider session. Surge plays a critical role in service of Uber’s mission to make transport accessible. We generate billions of dollars in annual gross bookings for the company by optimizing network efficiency and make a significant contribution to driver earnings. In addition to pricing, the signals we generate are some of the most important features used in practically every optimization/ML system across Uber. Although we are a backend team, what we do has an outsized impact on our riders because prices and reliability are two of the most important elements of customer experience. \-\-\-\- What the Candidate Will Do ---- You will work with a mixed team of Engineers, Operations Researchers, and Economists to build large-scale pricing optimization systems to set prices based on real-time marketplace conditions for Uber’s rides products globally. You will build ML models, conduct experiments, define monitoring metrics, and ensure good operational excellence at scale. You will help improve existing models through novel architectures and features in addition to identifying new applications and opportunities for Machine Learning. \-\-\-\- Basic Qualifications ---- 1. PhD or Masters in relevant fields (CS, EE, Math, Stats, etc.) with a focus on Machine Learning. 2. 3+ years of experience in an ML role with an emphasis on data and experiment driven model development. 3. Expertise in deep learning and optimization algorithms. 4. Experience with ML frameworks such as PyTorch and TensorFlow. 5. Experience building and productionizing innovative end-to-end Machine Learning systems. 6. Proficiency in one or more coding languages such as Python, Java, Go, or C++. 7. Good communication skills and ability to work effectively with cross-functional partners. 8. Good sense of ownership and tenacity toward hard machine-learning projects. \-\-\-\- Preferred Qualifications ---- 1. Experience in serving and monitoring online training systems such as real time recommendation systems. 2. Experience designing and implementing novel metrics for performance evaluation. 3. Experience handling time series data and time series forecasting (experience handling spatial temporal data is plus). 4. Deep understanding of models such as VAE (Variational Auto Encoder), SSM (State space model), and Normalizing Flow. 5. Experience in inference optimization and monitoring model performance efficiency and being able to identify bottlenecks. 6. Proven track record in conducting experiments and tracking models in high-complexity environments.
