About PromptArmor

PromptArmor is an AI security company based in San Francisco. We help the world's most demanding enterprises — Fortune 100 companies, leading healthcare systems, top 100 law firms, and institutional financial firms — assess and monitor the novel risks introduced by AI in their products and across their assets and ecosystem. Our research has uncovered critical vulnerabilities in major platforms like Slack and Writer.com, and we are focused on the net-new AI security problems that traditional tooling wasn't built to solve.

We're hiring engineers across the stack to help us build the platform, detections, integrations, and infrastructure that make this possible. The roles below describe what we look for; if you're excited about the mission but not sure which one fits, apply to whichever feels closest and we'll figure it out together.
