Full Job Description
đź“‹ Description
- • As an Application Security Engineer at Palantir Technologies Inc., you will play a critical role in safeguarding the integrity and security of software that powers mission-critical operations across defense, intelligence, healthcare, and commercial sectors. Your work directly enables Palantir’s customers to trust the platform with sensitive data, ensuring that lifesaving drugs are developed faster, supply chains remain resilient, and missing persons are located more efficiently—all through secure, resilient software.
- • Day to day, you will conduct comprehensive product security reviews using whitebox, greybox, and blackbox assessment methodologies across Palantir’s evolving product and service portfolio. You will collaborate closely with offensive security teams, engineering squads, and InfoSec colleagues to identify, analyze, and remediate vulnerabilities, translating findings into actionable hardening strategies that strengthen the platform against advanced persistent threats.
- • You will serve as the security subject matter expert for product architects and engineers, leading threat modeling exercises, assessing architectural risks, and guiding the implementation of security controls and mitigations. Your influence will help embed security-by-design principles into the core of Palantir’s development lifecycle, ensuring systems are secure-by-default from inception.
- • You will own and drive strategic, company-wide security initiatives—such as implementing software supply chain integrity frameworks (e.g., in-toto), deploying hardware-backed GPG key signing for code commits, building custom security automation tools, or scaling vulnerability management processes—empowering you to leave a lasting, transformative impact on Palantir’s security posture.
- • You will investigate and analyze security reports from internal sources, bug bounty programs, and trusted external partners, working hand-in-hand with incident response teams to triage, validate, and resolve product security incidents with speed and precision. Your curiosity and tenacity will be key in uncovering novel attack vectors and developing innovative detection and mitigation techniques.
- • Through this role, you will deepen your expertise in application security, threat modeling, secure software development lifecycle (SSDLC), and offensive/defensive security practices while working alongside some of the most skilled engineers in the industry. You’ll gain exposure to complex, high-stakes systems and have the autonomy to shape security strategy at a company whose technology influences global outcomes—building not just technical mastery, but the judgment and impact of a world-class security leader.
🎯 Requirements
- • Bachelor’s or Master’s degree in Computer Science, Information Security, or a related technical field, or equivalent practical experience.
- • Proven experience conducting security assessments (whitebox, greybox, blackbox) on complex software systems, including web applications, APIs, and distributed services.
- • Strong understanding of common vulnerabilities (OWASP Top 10, CWE/SANS Top 25), secure coding practices, and threat modeling methodologies (e.g., STRIDE, PASTA).
- • Proficiency in at least one programming language (e.g., Python, Java, Go, or TypeScript) and experience with security tooling (SAST, DAST, SCA, fuzzing).
- • Ability to communicate technical security risks clearly to both engineering and non-technical stakeholders, and to drive remediation through influence and collaboration.
- • Demonstrated curiosity, ownership mindset, and passion for solving hard security problems in high-impact environments.
🏖️ Benefits
- • Comprehensive health, dental, and vision insurance plans with flexible options for individuals and families.
- • Generous paid time off, including vacation, sick leave, and company holidays, plus parental leave policies supporting all caregivers.
- • 401(k) retirement plan with company matching to support long-term financial wellness.
- • Annual learning and development stipend for conferences, certifications, courses, and books to fuel continuous growth.
- • Remote-first work flexibility within the United States, enabling you to work from anywhere while staying connected to a mission-driven team.
- • Access to cutting-edge security research, internal tech talks, and opportunities to contribute to open-source security projects and internal tooling.
