We leverage more than 17 years of support to stakeholders across the federal government, with established and growing capabilities across Intelligence, Analytics, Engineering, Mission Support, and Communications disciplines. Founded in 2008, our mission is to transform the way our customers approach constantly changing and complex problem sets by bringing to bear the latest in technology and the highest caliber of talent.

Headquartered in Washington, DC’s historic Dupont Circle neighborhood, Barbaricum also has a corporate presence in Tampa, FL, Bedford, IN, and Dayton, OH, with team members across the United States and around the world. As a leader in our space, we partner with firms in the private sector, academic institutions, and industry associations with a goal of continually building our expertise and capabilities for the benefit of our employees and the customers we support. Through all of this, we have built a vibrant corporate culture diverse in expertise and perspectives with a focus on collaboration and innovation. Our teams are at the frontier of the Nation’s most complex and rewarding challenges. Join our team.

The Role

Our team members are subject matter experts in both cybersecurity and US Government policy. We’re excited about generating creative solutions to ambiguous security requirements. Our mission is deploying software in support of our customers’ most critical needs as quickly as possible while upholding the government’s trust. We achieve this through close consultation with stakeholders and direct ownership of the Authorization to Operate (ATO) process.

We’re seeking dedicated and motivated individuals with Systems Administration, Software Development, or Systems Engineering backgrounds to join our team as an Information System Security Officer (ISSO). You will collaborate with other Palantir engineers to ensure security policies and settings are in place, build standardized security documentation, and generate evidence of compliance once settings have been applied.

Core Responsibilities

• Achieve ATOs for Palantir software across multiple government customers with minimal oversight.
• Partner with engineers to analyze software, interpret security requirements, and plan effective control implementations.
• Provide outstanding customer service, policy expertise, and high-quality documentation.
• Serve as the primary in-person point of contact for one or more U.S. Government customers on cybersecurity and compliance requirements and questions.
• Independently interpret the findings of vulnerability scanning utilities such as ACAS (Tenable Nessus) and SCAP (STIG benchmark) and manage a Plan of Actions and Milestones (POA&M) for remediation of findings.

What We Value

• Proficiency in interpreting and communicating government policy to a diverse audience.
• Ability to multitask under pressure, using time management and organizational skills.
• Specific experience working in both traditional on premises environments and cloud environments such as Amazon Web Services (AWS).
• Experience accrediting IT systems against U.S. Government standards including NIST SP 800-53, CNSSI 1253, and the DISA STIGs, using frameworks like DOD RMF, ICD 503, or DIACAP.
• Initiative in proactively identifying problems before they arise and creativity in proposing solutions.

What We Require

• Active U.S. DoD Top Secret clearance with SCI eligibility.
• Active DOD 8140 or 8570 Certification (e.g. CISSP or Security+).
• Active IAT II certification.
• Minimum 2 years experience directly supporting a customer’s ATO/RMF process.
• Proven experience using the eMASS or XACTA accreditation management software systems.
• Be at customer site 5 days per week.
