• Drive security posture improvements through hardening standards, configuration management, vulnerability remediation, access controls, monitoring, and ongoing validation.
• Assess security risks in new platforms, products, architectures, vendors, and services, and turn findings into practical recommendations and engineering work.
• Build and maintain automation for security operations, including configuration validation, drift monitoring, patching, access reviews, policy enforcement, alert triage, and security hygiene.
• Partner with Identity, Infrastructure, Engineering, Legal, and other Information Security teams to strengthen security architecture and address recurring risks.
• Turn insights from assessments, red team exercises, incident investigations, and operational reviews into durable fixes, such as configuration changes, architectural improvements, policy updates, and automation.

• Familiarity with common infrastructure attack paths, adversary tactics, techniques, and procedures, and the controls used to prevent, detect, and contain them.
• The ability to assess complex environments and recognize how weaknesses across identity, endpoints, applications, networks, cloud services, or data flows can combine to create risk.
• Experience evaluating security tools and validating that controls are deployed effectively and continue to work as intended.
• Familiarity with infrastructure-as-code, configuration management, CI/CD, or other approaches to making security controls repeatable and scalable.
• The ability to own projects, make progress through ambiguity, and balance competing priorities while working well with colleagues.
• Experience in complex, high-assurance, regulated, or rapidly changing environments.
• Comfort moving between strategic problem-solving and hands-on technical work.
• Strong written and verbal communication skills, including the ability to explain technical risks and work with partner teams to drive remediation.
• Contributions to security programs, tooling, automation, incident investigations, or technical research—whether public or internal.
• 5+ years of hands-on experience in information security, infrastructure security, security engineering, security operations, or a closely related field.
• Demonstrated experience securing at least one major infrastructure or security domain, with the ability and interest to work across multiple domains.
• Active TS/SCI security clearance, or eligibility and willingness to obtain one.
• A strong sense of ownership, sound judgment, and integrity.

• Promoting health and well-being across all areas of Palantirians’ lives is just one of the ways we’re investing in our community.
• In keeping consistent with Palantir’s values and culture, we believe employees are “better together” and in-person work affords the opportunity for more creative outcomes. Therefore, we encourage employees to work from our offices to foster connectivity and innovation.
• Many teams do offer hybrid options (WFH a day or two a week), allowing our employees to strike the right trade-off for their personal productivity.
• Based on business need, there are a few roles that allow for “Remote” work on an exceptional basis. If you are applying for one of these roles, you must work from the city and or country in which you are employed. If the posting is specified as Onsite, you are required to work from an office.
