OpenAI's Foundations Search team is hiring a software engineer to build and scale retrieval infrastructure: indexing systems, retrieval pipelines, and serving layers, including low-latency, high-throughput services for real-time model interaction. The role covers dense, sparse, and hybrid retrieval, productionizing embedding and retrieval research, and co-designing model–system interfaces for agentic workflows, working with Pretraining, Inference, and Product teams. The posting asks for experience scaling distributed systems, a search, retrieval, or indexing background, familiarity with embedding-based or ML-powered systems, performance optimization, and production reliability.
