{"id":"ross-nordeen","title":"Ross Nordeen","content":"**Ross Nordeen** is an American technology professional known for his specialization in AI infrastructure and supercomputing. He was one of the eleven founding members of Elon Musk's artificial intelligence company, xAI. Before xAI, he held a key position at Tesla, contributing to its supercomputing infrastructure. On March 28, 2026, it was widely reported that he had departed from xAI, marking the exit of the last of the original eleven co-founders who had joined Musk to launch the company. [\\[1\\]](#cite-id-4YTiLwFDSDu59IZd) [\\[2\\]](#cite-id-DLanVmFKOklpekC6)​\n\n## Education\n\nNordeen is a graduate of Michigan Technological University (Michigan Tech). [\\[3\\]](#cite-id-Nk4ZipiCPPxrWeKW)​\n\n## Career\n\nNordeen's career has been closely tied to Elon Musk's technology ventures, with significant roles at both Tesla and xAI, focusing on the critical infrastructure needed for large-scale artificial intelligence development. [\\[3\\]](#cite-id-Nk4ZipiCPPxrWeKW) [\\[1\\]](#cite-id-4YTiLwFDSDu59IZd)\n\n### Tesla\n\nPrior to co-founding xAI, Nordeen worked at Tesla for nearly four years as a Technical Program Manager within the supercomputing and machine learning division. [\\[1\\]](#cite-id-4YTiLwFDSDu59IZd) A 2021 organizational chart identified him as serving on the Autopilot team. In this capacity, he was instrumental in managing technical programs for AI hardware initiatives and building out the data center infrastructure used for training Tesla's Full Self-Driving (FSD) neural networks. His responsibilities included coordinating between engineering teams, overseeing resource allocation, directing project timelines for high-performance computing (HPC) projects, and performing risk assessments. His work was considered foundational to scaling Tesla's HPC capabilities, which support the company's autonomous driving programs and other AI development efforts. [\\[1\\]](#cite-id-4YTiLwFDSDu59IZd) [\\[3\\]](#cite-id-Nk4ZipiCPPxrWeKW)\n\nFollowing Elon Musk's acquisition of Twitter in October 2022, Nordeen was reportedly part of a group of several dozen engineers from Tesla and SpaceX who were brought in to assist with coordinating large-scale staff reductions at the newly acquired social media company, later rebranded as X. [\\[3\\]](#cite-id-Nk4ZipiCPPxrWeKW)\n\n### xAI\n\nIn July 2023, Ross Nordeen was publicly announced as one of the twelve founding members of xAI, a new artificial intelligence company led by [Elon Musk](https://iq.wiki/wiki/elon-musk). The founding team was composed of experts from prominent AI research labs, including DeepMind and Google Research. [\\[1\\]](#cite-id-4YTiLwFDSDu59IZd) At xAI, Nordeen served as a Member of the Technical Staff and reported directly to Musk. He was described by *Business Insider* as Musk's \"right-hand operator,\" tasked with coordinating the company's priorities and driving execution across all initiatives. [\\[3\\]](#cite-id-Nk4ZipiCPPxrWeKW) [\\[4\\]](#cite-id-UJQ9IC8ppcvQOnmk)\n\nLeveraging his background from Tesla, Nordeen played a foundational role in building xAI's core technical and physical infrastructure from its inception. He served as the lead strategist for the company's data center planning, which involved site selection, energy strategy, and scaling capacity to accommodate the immense compute resources required for training large-scale AI models. His work included leading negotiations for major data center projects, including discussions for multi-gigawatt leases with the Saudi firm Humain. He also provided technical oversight for AI hardware expansions and the integration of high-density power solutions, while planning for future energy independence through on-site power generation. [\\[1\\]](#cite-id-4YTiLwFDSDu59IZd)\n\n## Departure from xAI\n\nReports surfaced on March 28, 2026, that Ross Nordeen had left xAI. His departure was highly significant as he was the last of the original eleven co-founders to leave the company, making [Elon Musk](https://iq.wiki/wiki/elon-musk) the sole remaining member of the founding team. [\\[2\\]](#cite-id-DLanVmFKOklpekC6) [\\[3\\]](#cite-id-Nk4ZipiCPPxrWeKW) [\\[5\\]](#cite-id-zbNXXJq42iSHtrQN) According to some reports, he officially left on March 27, 2026, in the same week as fellow co-founder Manuel Kroiss, whose exit preceded Nordeen's. [\\[4\\]](#cite-id-UJQ9IC8ppcvQOnmk)​\n\nThe complete turnover of the founding team within approximately 32 months of the company's launch marked a major transition for xAI. The exodus occurred less than two months after SpaceX formally acquired xAI on February 2, 2026, in a deal that reportedly valued the AI company at $250 billion. [\\[4\\]](#cite-id-UJQ9IC8ppcvQOnmk)​\n\nNordeen's departure also followed public comments made by [Elon Musk](https://iq.wiki/wiki/elon-musk) on March 13, 2026, stating that xAI was \"not built right the first time around\" and that it needed to be \"rebuilt from the foundations up.\" News of Nordeen's exit corroborated by the removal of the xAI employee badge from his profile on the social media platform X. [\\[3\\]](#cite-id-Nk4ZipiCPPxrWeKW) [\\[4\\]](#cite-id-UJQ9IC8ppcvQOnmk)​\n\n## Personal Life and Relationships\n\nNordeen maintained a close professional relationship with [Elon Musk](https://iq.wiki/wiki/elon-musk), having followed him from Tesla to co-found xAI, where he served as a key operational lead and direct report. According to Walter Isaacson's biography of [Elon Musk](https://iq.wiki/wiki/elon-musk), Nordeen is also a longtime friend of James Musk, [Elon Musk](https://iq.wiki/wiki/elon-musk)'s cousin, a relationship that predates his direct work with the billionaire entrepreneur.
