We offer highly competitive benefits and pride ourselves in being a great place to work with a shared sense of purpose.

About the Role

General Dynamics Mission Systems currently has a career opportunity for an IT System Administrator for our Restricted Ground Systems. As a member of our Information Assurance Security team, you will support Information System (IS) Risk Management Framework activities ranging from categorizing systems and preparing IS packages to reviewing vulnerability scans, executing Change Control processes, and supporting system upgrades during program execution.

In this role, you will maintain the day-to-day security posture and continuous monitoring of Information Systems for DoD security programs. Your work includes security event and information management review and analysis, end-user account audits, and performing weekly system audit reviews. You will execute security testing to ensure the correct implementation of security controls and support the assessment and mitigation of vulnerabilities throughout a system's life cycle. Additionally, you will perform incident response and cleanup actions when necessary and ensure systems are operated, maintained, and disposed of in accordance with internal security policies outlined in the System Security Plan (SSP).

Are you up to the challenge? You will have the opportunity to identify opportunities to apply AI for continuous improvement and innovation. We are looking for a self-starter with the ability to operate independently with minimal supervision, as well as someone who can work collaboratively in a cross-functional team throughout the system life cycle.

Hiring Process & Requirements

Due to the nature of the work performed within our facilities, U.S. citizenship is required. Applicants selected will be subject to a U.S. Government security investigation and must meet eligibility requirements for access to classified information.
