Job Description

MAXISIQ is seeking a highly skilled Junior Security Engineer to maintain responsibility for all duties in support of Department of Defense (DoD), Risk Management Framework (RMF), and Intelligence Community Directive (ICD) 503, while applying strong security engineering principles and hands-on technical expertise. In addition to intermediate to advanced knowledge of NIST SP 800-53 security controls and CNSSI 1253, this role emphasizes engineering experience across system hardening, automation, and vulnerability remediation.

You will provide systems security engineering and architecture principles in support of RMF, including specification, design, development, implementation, and modification of information system components. The successful candidate will not only select, tailor, and implement NIST SP 800-53 security controls for RMF Assessment and Authorization (A&A) but also actively engineer solutions to remediate vulnerabilities and improve system security posture.

This is a hybrid role with possible locations in San Antonio, Augusta and the Fort Meade area.

Key responsibilities include:

• Assist developing layered protections and establish cybersecurity SOPs or guidelines for authorization boundaries.
• Perform vulnerability management and implement fix actions across Windows, Linux/Unix, and containerized environments.
• Engineer and automate and deploy security remediation configurations using tools such as Ansible and scripting in Python and Bash.
• Implement and maintain DISA STIGs and CIS Benchmarks across diverse platforms, including RHEL, Ubuntu, Windows operating systems, VMware/ESXi, and 3rd-party applications, as well as network devices such as Cisco (NXOS, ASRs, IOS-XE, ASA) and Juniper.
