OpenAI's robotics hardware lead is out. Caitlin Kalinowski, who oversaw hardware within the robotics division of OpenAI, posted on X that she was resigning from her role, while criticizing the company's haste in partnering with the Department of Defense without investigating proper guardrails. OpenAI told Engadget that there are no plans to replace Kalinowski.

Kalinowski, who previously worked at Meta before leaving to join OpenAI in late 2024, wrote on X that "surveillance of Americans without judicial oversight and lethal autonomy without human authorization are lines that deserved more deliberation than they got." Responding to another post, the former OpenAI exec explained that "the announcement was rushed without the guardrails defined," adding that it was a "governance concern first and foremost."

OpenAI confirmed Kalinowski's resignation and said in a statement to Engadget that the company understands people have "strong views" about these issues and will continue to engage in discussions with relevant parties. The company also explained in the statement that it doesn't support the issues that Kalinowski brought up.

"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 OpenAI statement read.

Kalinowski's resignation may be the most high-profile fallout from OpenAI's decision to sign a deal with the Department of Defense. The decision came just after Anthropic refused to comply with lifting certain AI guardrails around mass surveillance and developing fully autonomous weapons. However, even OpenAI's CEO, Sam Altman, said that he would amend the deal with the Department of Defense to prohibit spying on Americans.

Correction, March 8 2026, 10:30AM ET: This story has been updated to correct Kalinowski's role at OpenAI to "robotics hardware lead" instead of "head of robotics."
