Staff Machine Learning Engineer - Marketplace

About the Role & Team

The Marketplace Signals team at Uber is responsible for building and optimizing foundational marketplace signals that power user experiences and drive marketplace efficiency. Our team ensures that key signals-such as eyeball ETA, spinner time, and supply reliability indicators-are leveraged effectively across various Uber products and levers, enabling data-driven decision-making and seamless coordination across different business functions.

What You'll Do

- Develop and optimize ML models to enhance key marketplace signals (e.g., ETA predictions, supply availability metrics, demand forecasts).
- Collaborate with cross-functional teams (Pricing, Matching, Driver Incentives, etc.) to ensure marketplace signals are effectively utilized.
- Improve operational efficiency by building a centralized, scalable system for marketplace signals that serves multiple use cases.
- Leverage cutting-edge ML techniques (deep learning, probabilistic modeling, reinforcement learning, etc.) to continuously refine marketplace signals.

What You'll Need

- Strong problem-solving skills, with expertise in ML methodologies
- Experience in applying ML, statistics, or optimization techniques to solve large-scale real-world problems (e.g. ads tech, recommender systems)
- Experience in ML frameworks (e.g. Tensorflow, Pytorch, or JAX) and complex data pipelines; programming languages such as Python, Spark SQL, Presto, Go, Java

Why Join Us?

- Work on high-impact machine learning problems that directly improve Uber's marketplace efficiency.
- Influence key business levers that optimize Uber's pricing, matching, and rider/driver experience.
- Build centralized marketplace signals that reduce redundancy and improve operational efficiency.
- Join a high-caliber, innovative team tackling some of the hardest ML challenges in the industry.

If you're passionate about using ML to optimize real-world systems at a massive scale, we'd love to hear from you!

Basic Qualifications:

- Ph.D. or M.S. in Statistics, Economics, Mathematics, Computer Science, Machine Learning, Operations Research, or other quantitative fields.
- 6+ years of industry experience in machine learning, including building and deploying ML models at scale.
- Experience in modern deep learning architectures and probabilistic modeling
- Proficiency in programming languages (Python, Java, Scala) and ML frameworks (TensorFlow, PyTorch, Scikit-Learn),
- Solid understanding of MLOps practices, including design documentation, testing, and source code management with Git.
- Advanced skills in the development and deployment of large-scale ML models and optimization algorithms
- Strong business and product sense: ability to shape vague questions into well-defined analyses and success metrics that drive business decisions.

Preferred Qualifications:

- Expertise in developing causal inference methodologies, experimental designs, and advanced analytical methods.
- Strong experience in building a wide range of models (e.g. causal inference, optimization, ML) for business applications.
- Experience in algorithm development and rapid prototyping.
- Design, develop, and operationalize econometric models to assess challenging causal problems such as product incrementality and long-term value
- Propose, design, and analyze large-scale online experiments and interpret the results to draw actionable conclusions.
- Ability to drive clarity on the best modeling solution for a business objective.
- Collaborate with cross-functional teams across disciplines such as product, engineering, and operations to drive system development end-to-end from generating ideas to productionizing.
