Information Security Engineer - Infrastructure Security

A World-Changing Company:

Palantir builds the world’s leading software for data-driven decisions and operations. By bringing the right data to the people who need it, our platforms empower our partners to develop lifesaving drugs, forecast supply chain disruptions, locate missing children, and more.

The Role:

We're looking for someone who has spent years thinking adversarially about Windows and Active Directory — not just operating them, but understanding every layer of how they can be abused, detected, and hardened. If you've written detections for DCSync, built hunting pipelines around Kerberos ticket anomalies, or reverse-engineered a novel persistence mechanism in a Windows kernel driver, this is the team you want to be on.

As an Information Security Engineer focused on Windows and Active Directory, you'll own the security of Palantir's global Windows infrastructure. Your team runs 24/7 prevention, detection, and investigation of security events across our entire environment. The adversaries we face are sophisticated. We need someone who is more so.
