Software Engineer II - Engineer
Job Description
Software Engineer — Delivery Search
About the Role
We are seeking talented Software Engineers to join our Search Engineering team and help build the next generation of AI-powered search experiences across Uber Eats, Grocery, and Retail.
In this role, you will build and improve large-scale backend systems that power search retrieval, ranking, query understanding, and emerging LLM-based search experiences. You will work on high-throughput, low-latency services that retrieve and rank relevant restaurants, stores, dishes, and items from large catalogs in real time.
You will collaborate closely with backend and ML engineers, data scientists, product managers, and platform teams to improve search quality, latency, scalability, and reliability. You will have opportunities to work across traditional search infrastructure, semantic retrieval and machine learning, as well as emerging LLM-powered retrieval, ranking, and search experiences.
About the Team
The Delivery Search team builds the core search technology behind Uber Eats, Grocery, and Retail. We work across the search stack, including query understanding, indexing, lexical and semantic retrieval, ranking, model serving, and search serving infrastructure.
Our work combines large-scale distributed systems, information retrieval, machine learning, and increasingly LLMs and generative AI to solve challenging problems around relevance, latency, scalability, and reliability. The team owns systems serving millions of users and is evolving the search stack toward more intelligent, real-time, and AI-powered architectures.
