Information Systems Security Officer (Prime)

Annapolis Junction, MD
Full Time
Mid Level

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

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way.
