Senior Data Scientist, Machine Learning - Dasher & Logistics at DoorDash
Come help us build the world's most reliable on-demand, logistics engine for delivery! We are bringing on talented senior Data Scientists to help us develop and improve the machine learning, operations research, and reinforcement learning models that power DoorDash's three-sided marketplace of consumers, merchants, and dashers. We are looking for Computer Scientists, Statisticians, Economists, Physicists, Mathematicians, and other senior quantitative researchers from all disciplines.
DoorDash is at an exciting point in its machine-learning maturity curve where a lot of the "easy" prediction work has been completed but more sophisticated techniques still have the capacity to drive incredible value for the company. DoorDash is also still small enough (~400 engineers) that over the course of a year each of us is able to work on a large set of problems that touch many different facets of the business.
As a senior Data Scientist, you will have the opportunity to leverage our robust data and machine learning infrastructure to develop inference and optimization models that impact millions of users across our three audiences and tackle our most challenging business problems. You will work with other data scientists, engineers, analysts, and product managers to develop and improve models to help us grow our business.
What You'll Do
- Design always-on experiments/contextual bandits algorithms to improve the marketplace impact of machine learning models trained on unreliable data
- Deploy real-time geospatial forecasting tools to predict future supply and demand and inform our dasher/order matching and dasher positioning systems
- Build the next generation version of those systems using network flow, dynamic programming, queuing, and/or reinforcement learning-based approaches
- Develop in-app machine learning algorithms that gracefully handle data censorship
- Deploy causal machine learning/heterogeneous treatment effects modeling to develop personalized dasher mobilization incentives to more effectively balance supply & demand
What We're Looking For
- 3+ years of industry experience developing prediction, inference, and optimization models that move business-critical metrics — more experience preferred
- Masters or PhD in Computer Science, Statistics, Economics, Mathematics, Physics, Robotics, Operations Research, or other quantitative field
- Experience with at least two of the following areas: classical machine learning, deep learning, reinforcement learning/control systems, probability theory, statistics, causal inference, time series forecasting, optimization, dynamic programming
- Demonstrated coding and programming abilities (Python preferred). Software engineering experience is a plus, but not required
- A track record of prioritizing & delivering business impact
