The Places Data Team owns Uber's "Ground Truth" — the definitive dataset of POIs, Addresses, Building Footprints, and Entrances that powers the core of every journey: the beginning and the end. Without accurate place data, a ride doesn't start, and a courier can't deliver. We operate at massive scale (billions of places), solving inference and conflation problems using ML to match and summarize data from dozens of providers. As a Senior ML Engineer, you'll build production ML systems focusing on places matching, attributes inference, summarization, friction detection, etc.
Job Responsibility:
Design, develop and productionize end-to-end ML solutions for places data conflation (POI, addresses, BFP, etc.) and attribute inference using a mix of classical ML, deep learning, and generative AI
Collaborate with product, science, and engineering teams to execute on the technical vision and roadmap
Conduct rigorous experimentation and A/B testing to validate model performance and iterate on improvements
Own projects from initial mathematical formulation through to prototyping, algorithm implementation, and large-scale experimentation in production
Raise the technical bar for the team. You will mentor L3/L4 engineers, lead complex code reviews, and foster a culture of engineering excellence and scientific rigor
Requirements:
Ph.D., M.S. or Bachelor's degree in Computer Science, Machine Learning, or Operations Research, or equivalent technical background with exceptional demonstrated impact
4+ years of experience in developing and deploying machine learning models and optimization algorithms in large-scale production environments, delivering measurable business impact over multiple quarters and making significant technical contributions
Proficiency in programming languages such as Python, Scala, Java, or Go
Experience with large-scale data systems (e.g. Spark, Ray), real-time processing (e.g. Flink), and microservices architectures
Experience in the development, training, productionization and monitoring of ML solutions at scale, ranging from offline pipelines to online serving and MLOps
Nice to have:
Deep understanding of CS fundamentals, software engineering principles, and modern development methodologies
Direct experience in GIS, matching algorithms
Expertise in large-scale data systems like Spark, Hive, and Presto
Experience building and optimizing gradient boosting and deep learning models
Background in Optimization or Causal Inference applied to business problems
Exceptional problem-solving, critical thinking, and communication skills, with the ability to influence leadership and present complex technical trade-offs to non-technical stakeholders
