Job description

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 an Information Security Engineer who can think broadly about how infrastructure is built, attacked, defended, and improved. You may have deep experience in one area—such as endpoint security, Active Directory, Data Loss Prevention, cloud security, identity, or detection and response—but you’re motivated by solving security problems across the environment.

As an Information Security Engineer focused on infrastructure security, you'll help protect Palantir's global endpoints, servers, identity systems, applications, networks, and data flows. You'll work across teams to reduce attack surface, improve defensive controls, investigate security events, and turn security findings into durable architectural and operational improvements.

This is not just a corporate security role; the adversaries we face are sophisticated. We need someone who understands both the details and the broader system: how a weakness in one part of the environment can create risk somewhere else, how controls interact, and how to build security improvements that hold up in practice.
