Job description

Wraithwatch was founded by security engineers from SpaceX, Palantir, and Anduril to build the next generation of AI‑powered cyber defense systems for the United States and its allies. We are deployed today to customers spanning Fortune 500, US Federal Government, commercial nuclear, aerospace, defense, maritime, and other emerging technology companies. Our core product is a cyber defense platform utilizing generative artificial intelligence agents to autonomously model a digital twin of an organization's entire IT and cybersecurity environment and analyze it for weaknesses, misconfigurations, and chains of possible attack.

Wraithwatch Security Engineers ensure our artificial intelligence engines can perceive and rapidly manipulate a wide variety of integrated cybersecurity tools, as well as optimize their autonomous reasoning and analysis on complex cybersecurity tasks. They'll also own Wraithwatch's internal corporate cybersecurity posture across our company endpoints, cloud environments, and build pipelines.
