Information Security Engineer Jobs

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 Information Security's mission is to secure Palantir, and by extension, protect our customers and the critical data they trust us with. We want someone whose technical skill is matched by integrity and genuine curiosity about security. You'll thrive here if you're self-motivated, collaborative, and energized by hard problems with no manual. Much of our work is ambiguous by design; if chasing clear outcomes down unclear paths excites you more than it unsettles you, you'll fit right in. This internship comes with real impact, real autonomy, and the resources to make meaningful security improvements across Palantir. Backgrounds vary. What matters is curiosity, tenacity, and a drive to become a world-class security engineer. You'll be treated like a full-time engineer, given real ownership, trusted with real projects, and accountable for outcomes our customers depend on.

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.

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 Palantir's Offensive Security team probes our own products, infrastructure, and cloud environment the way a real attacker would. As an Offensive Security Engineer, you will test internal applications and infrastructure, chain findings into realistic attack paths, and work directly with the engineers responsible for the affected systems to get issues closed. A growing part of the team’s work is also developing agentic offensive security tooling: LLM-driven systems that encode operator tradecraft and apply it continuously. You will help in the design of that tooling and prove it out on live assessments. You will also help to coordinate third-party penetration testing engagements, scoping the work with specialized external firms, keeping assessments focused on the risks that matter, and turning their results into concrete remediation.
