Job description

Make an Impact Where It Matters Most

At Intelliforce, we help mission systems stay secure, compliant, and ready for operational use. In this role, you will support Analytical Application Integration by helping maintain the security posture of mission systems, supporting Information Assurance activities, and ensuring security policies, standards, and procedures are followed throughout the system lifecycle.

You will work alongside systems engineers, software engineers, security professionals, and mission stakeholders to help protect classified information, maintain required documentation, assess security impacts, and support day-to-day security operations.

What Makes This Opportunity Stand Out

This role gives you hands‑on exposure to the security side of mission systems. You will work across system security documentation, configuration management, vulnerability and risk assessment, authorization activities, policy compliance, and operational security.

Rather than sitting outside the engineering process, you will work closely with the teams building and sustaining the systems. You will help evaluate changes, understand their security impact, maintain accurate security documentation, and support the controls that keep mission systems authorized and operational.

At Intelliforce, your work is visible and your judgment matters. Because we support prime programs, our teams stay close to meaningful mission work and the people relying on these systems. Because we are a small business, leadership is accessible, communication is direct, and strong performance gets noticed. Add in long‑term stability, strong benefits, and a people‑first culture, and this is an opportunity to grow your security expertise while supporting real mission systems.

Here’s What Your Day-to-Day Could Include

• Support the information assurance program for systems and related mission environments
• Help implement and enforce information systems security policies, standards, and methodologies
• Maintain the operational security posture of supported systems
• Perform day-to-day security operations and support system security activities
• Assist with evaluating security solutions for systems processing classified information
• Support vulnerability and risk assessment activities
• Help manage configuration changes and assess the security impact of those changes
• Maintain configuration management records for security‑relevant software, hardware, and firmware
• Prepare and update System Security Plans, Risk Assessment Reports, C&A packages, and System Requirements Traceability Matrices
• Support security authorization activities in accordance with NIST RMF
• Maintain records for workstations, servers, routers, firewalls, switches, and other infrastructure components
• Support the ISSM and senior ISSOs in maintaining the appropriate operational IA posture
• Assist with user identification and authentication mechanisms
• Keep security documentation current as systems evolve

Minimum Qualifications

• Clearance: Top Secret Clearance with Full Scope Polygraph, must be active. We do not have the ability to sponsor clearances
• Citizenship: Must be a U.S. Citizen. We cannot sponsor visas
• Five years of experience as an ISSO on programs and contracts of similar scope, type, and complexity
• Experience in at least one of the following areas: current security tools, hardware or software security implementation, communication protocols, or encryption techniques and tools
• Bachelor’s degree in Computer Science or a related discipline from an accredited college or university
• Four additional years of ISSO experience may be substituted for the bachelor’s degree
• DoD 8570 compliance with IAT Level I or higher

Required Skills

• Experience implementing and enforcing information systems security policies, standards, and methodologies
• Experience preparing and maintaining security documentation
• Experience evaluating security solutions for classified information systems
• Experience with configuration management for security‑relevant software, hardware, and firmware
• Experience maintaining system and infrastructure records
• Experience supporting Certification and Accreditation activities
• Knowledge of ODNI and DoD security policies
• Experience developing or maintaining System Security Plans
• Experience maintaining operational security posture
• Experience supporting ISSM and senior ISSO activities
• Experience performing day‑to‑day security operations
• Understanding of user identification and authentication mechanisms
• Strong documentation and attention‑to‑detail skills

Desired Skills

• Experience supporting NIST Risk Management Framework activities
• Experience preparing Risk Assessment Reports
• Experience supporting System Requirements Traceability Matrices
• Experience assessing security impacts associated with system changes
• Familiarity with vulnerability and risk assessment processes
• Familiarity with security controls for classified systems
• Experience supporting secure mission or operational environments
