TL;DR · Staff Machine Learning Engineer, Core Services Eng, GenAI

As a Staff Machine Learning Engineer on Uber’s Customer Obsession team in San Francisco or Sunnyvale, you will architect, productionize, and scale an autonomous support agent that resolves customer issues across mobile, web, and voice platforms. Your day-to-day responsibilities include owning the end-to-end agent architecture, advancing retrieval and reasoning pipelines, establishing evaluation frameworks for safety and efficiency, driving automation at scale to reduce cost per contact, and mentoring senior engineers on technical strategy and quality standards. The role requires deep expertise in LLM-driven systems, including inference optimization and prompt design, as well as a track record of shipping customer-facing intelligent experiences with measurable impact. Preferred qualifications include experience with agentic architectures, support automation for large consumer platforms, multilingual NLU/NLG, and balancing speed and reliability at scale.

What you'll do

  • Own the end-to-end architecture of an autonomous support agent including planning, execution, long-term memory, and policy enforcement.
  • Develop advanced retrieval and reasoning pipelines for the agent to search across knowledge sources and apply policies effectively.
  • Create evaluation frameworks with safety tests and LLM-as-judge mechanisms integrated into CI/CD systems.
  • Drive automation strategies to enhance customer experience and reduce cost per contact through partnerships with Product/Design/Operations teams.
  • Mentor senior engineers on technical strategy, quality standards, and best practices for agentic patterns and reliability.

What we're looking for

  • 7+ years of experience building production ML/AI systems and leading complex initiatives.
  • Deep expertise in LLM-driven systems including optimization, prompt design, safety, and evaluations.
  • Track record of shipping customer-facing intelligent experiences with measurable impact through A/B testing.
  • Experience with agentic architectures and retrieval-augmented generation (RAG) over policy-heavy knowledge bases.
  • Practical experience balancing speed and reliability at scale for large consumer platforms.
