Palantir Offensive Security Engineer at Palantir responsible for testing internal applications and infrastructure by simulating real attacker methods. Develop agentic offensive security tooling and coordinate third-party penetration testing engagements.
Responsibilities
- 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.
