About The Position

Oracle's Hardware Development Organization is seeking an experienced On-Board Power Engineer for its Server Development team in Santa Clara, California, or Burlington, Massachusetts. The role focuses on architecting, designing, and integrating on-board power delivery subsystems for next-generation AI servers using merchant silicon for compute, storage, and communications. These systems have demanding power requirements and emphasize highly efficient solutions for Oracle's AI cloud and vertically integrated rack-level products. The Electrical Design Engineer will own power subsystem and board-level architecture and detailed design throughout product development, through transition to volume production. The role requires keeping current with developments in power delivery and applying them to reliable Oracle solutions. The engineer may also advise on power systems from previously delivered products.
