Job Description:

Our products support some of the most important and impactful work in the world, including defense, intelligence, and commercial applications. We are trusted by our customers to protect their mission-critical information in the face of advanced persistent threats. The mission of the Application Security Team is to enable developers to be highly productive, agile, and produce the most secure software possible. Given the mission critical work that Palantir does, investments in application security have never been more important. As an Application Security Engineer, you will be hands-on and have wide-ranging impact for the security of Palantir: • Product security reviews. You will perform full-scope security reviews of our current and future product and service portfolio. This includes whitebox, greybox, and blackbox assessments. You will work with offensive security teams, engineering teams, and other members of the InfoSec organization to harden our products against our dedicated adversaries. • Architecture and design. You will be the security subject matter expert for product architects and engineers. You will threat model, assess risks, and help implement security controls and mitigations to address identified issues. You will directly steer the design of our products to ensure we are secure-by-default. • Strategic security initiatives. You will be empowered to own transformational security initiatives that impact the whole company. Members of the Application Security Team have implemented software supply chain security controls (e.g., in-toto), implemented hardware-backed GPG key signing for commits, developed new security services, implemented security automation, or worked on massive-scale security problems. • Vulnerability identification and analysis. You will be responsible for finding new and novel ways to identify and resolve security vulnerabilities in our products. This includes static and dynamic code analysis, security scanning, investigation of security reports from InfoSec, our bug bounty program, or other trusted partners, and direct work with our incident response team on product security issues and incidents.
