All employees are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.  About the Role The foundation team at xAI is dedicated to building the infrastructure and systems that empower maximum truth-seeking AI agents. To achieve this, we are developing AI-first search/retrieval systems that enable LLM agents to efficiently access, process, and leverage vast knowledge bases — ultimately fostering agents that prioritize accuracy, rigorous reasoning, and an unbiased pursuit of knowledge. We are seeking expert engineers to architect and scale retrieval/search systems for data in all modalities (text, images, video, and audio) to elevate agent reasoning and decision-making. Tech Stack Python Rust / C++ Vector databases Spark Focus Design and develop a real-time, web-scale search engine for LLM agent consumption, with a core goal of supporting maximum truth-seeking capabilities. Design and develop advanced techniques for precise and efficient search indexing, retrieval, and ranking at trillion-document scale across modalities. Integrate the search engine with xAI's core models to improve accuracy, speed, and relevance in real-time agent interactions, ensuring agents can discern and prioritize truthful information, while minimizing hallucinations. Ensure robustness and scalability of search infrastructure under high-load conditions while aligning with truth-seeking objectives. Ideal Experiences (at least one from below) Expertise in building web-scale search engines, including but not limited to: indexing, information retrieval, search ranking, hybrid search, structured search, and semantic search. Strong engineering background with a passion for building high-performance, scalable distributed systems and optimizing latency and throughput. Experience working with LLMs, agents, embedding models, or knowledge-intensive tasks, including fine-tuning for retrieval tasks aimed at enhancing truthfulness. Proficient in managing and curating large datasets from diverse sources, with a focus on quality, verifiability, and efficiency to support maximum truth-seeking agents. Preference for candidates with extensive experience in building and scaling web-scale search engines, including hands-on involvement in production systems and experimental iterations. Location The role is based in the Bay Area [San Francisco and Palo Alto]. Candidates are expected to be located near the Bay Area or open to relocation.
