Caitlin Kalinowski, a prominent figure in hardware and robotics engineering, has announced her resignation from OpenAI, a move that underscores growing internal dissent regarding the company’s engagement with military applications of artificial intelligence. Her departure, made public through posts on X and LinkedIn, signals a principled stand against what she described as insufficient deliberation over domestic surveillance without judicial oversight and the potential for lethal autonomous weapons systems lacking human authorization. Kalinowski had been leading hardware and robotic engineering teams at OpenAI since November 2024.
“This was about principle, not people,” Kalinowski stated in her announcement, emphasizing her deep respect for OpenAI CEO Sam Altman and the teams she worked with. Her decision highlights a critical ethical crossroads for AI developers as the technology increasingly intersects with national security interests. The timing of her exit is particularly salient, following a period of intense negotiation and public scrutiny surrounding AI companies’ partnerships with the U.S. military.
Just days prior to Kalinowski’s announcement, discussions between the Pentagon and Anthropic, another leading AI firm, reportedly collapsed. Anthropic had sought to impose stringent limitations on how its technology could be used for domestic surveillance and autonomous weaponry. In contrast, OpenAI subsequently finalized its own agreement with the Defense Department, which involves deploying its models on a classified government network. This development drew swift criticism, with some observers and even internal employees suggesting OpenAI had acted opportunistically in the void left by Anthropic’s refusal.
Sam Altman, OpenAI’s CEO, later conceded that the rollout of their Pentagon deal might have appeared “opportunistic.” The company has since attempted to clarify and reinforce restrictions on how its systems can be utilized by the military. An OpenAI spokesperson confirmed Kalinowski’s departure and reiterated the company’s position, stating, “We believe our agreement with the Pentagon creates a workable path for responsible national security uses of AI while making clear our red lines: no domestic surveillance and no autonomous weapons.” The spokesperson also acknowledged the strength of differing views on these issues and committed to ongoing dialogue with employees, government bodies, civil society, and global communities.
Kalinowski’s career trajectory before joining OpenAI reflects a deep expertise in cutting-edge hardware development. Prior to her stint at the AI giant, she served as a hardware executive at Meta for nearly two and a half years. During this period, she spearheaded the creation of Orion, an ambitious project Meta touted as “the most advanced pair of AR glasses ever made,” which saw its prototype unveiled in September. Her tenure at Meta also included more than nine years working on virtual reality headsets for Oculus, a Meta-owned subsidiary. Before her extensive work in augmented and virtual reality, Kalinowski spent nearly six years at Apple, contributing to the design of MacBook models, including the Pro and Air lines. Her background underscores a career dedicated to bringing complex technological visions to fruition across some of the most influential companies in the tech sector. Her resignation from OpenAI now adds a significant voice to the ongoing ethical debate surrounding artificial intelligence and its societal implications.
