Information Systems Security Officer (ISSO)

Leidos is seeking a driven Information System Security Officer (ISSO) to join our team at Fort Bliss, Texas!

This is a high-impact role where you’ll be at the forefront of protecting mission-critical systems. Candidates must already hold a current TS/SCI security clearance to be considered. As an ISSO, you’ll deliver expert Cybersecurity support services, partnering with the ACC Cybersecurity Chief Information Security Officer and unit ISSOs to maintain a powerful, effective program that safeguards the confidentiality, integrity, and availability of AF IC information resources.

What You’ll Do

• Lead the charge in developing local unit Cybersecurity programs and security plans in alignment with ACC, AF, IC, and DoD guidance.
• Dive deep into data—analyze compliance, track progress, and report results on Cybersecurity programs, POA&Ms, A&A workflow tools, patch management, IAVA alerts, DoD 8570.01M certifications, FISMA compliance, and ATOs to unit leadership and higher headquarters.
• Collaborate and advise—work with local units and HHQ IISMs to deliver assessments, recommend courses of action, and provide solutions that strengthen Cybersecurity programs.
• Empower others—develop and deliver hands-on training to government civilians, contractors, and military personnel on IT security tools, policies, and procedures to ensure resources are protected and standards are met.

What You Bring

• TS/SCI clearance on day one—ready to hit the ground running.
• Bachelor’s degree and 10+ years of relevant experience or Master’s degree and 6+ years of relevant experience (or equivalent experience in lieu of degree).
• Current IAT Level II certification required.
• Proven expertise with Assessment and Authorization documents, assessments, and Cybersecurity program tasks.
• At least two years of experience with AF and IC plans and policies.

This isn’t just another Cybersecurity role—it’s a chance to make a direct impact on national security while working alongside some of the best in the field.
