Documentation

• Create and maintain technical documentation for configurations and engineering procedures.
• Update implementation guides, troubleshooting documentation, and engineering runbooks.
• Document technical changes and configuration decisions.
• Assist with maintaining architecture diagrams and technical inventories.
• Contribute solutions and lessons learned to team knowledge bases.
• Follow established documentation standards to ensure work is repeatable and supportable.

Team Collaboration & Development

• Work closely with CMMC engineers and other technical resources to complete assigned engineering tasks.
• Participate in technical training, knowledge-sharing sessions, and team meetings.
• Develop knowledge of CMMC, NIST SP 800-171, Microsoft security technologies, and cybersecurity engineering practices.
• Collaborate with other RSM Defense engineering and service teams when troubleshooting or implementing shared technologies.
• Seek guidance from senior engineers when encountering unfamiliar technologies or complex technical requirements.
• Continuously develop technical skills through hands-on experience, training, labs, and industry certifications.

Required Skills & Knowledge

• Foundational understanding of cybersecurity concepts and security best practices.
• Basic knowledge of Microsoft Windows operating systems.
• Familiarity with Microsoft 365, Azure, or other cloud technologies.
• Basic understanding of networking concepts including TCP/IP, DNS, DHCP, firewalls, and VPNs.
• Understanding of identity and access management concepts such as user accounts, permissions, MFA, and least privilege.
• Basic troubleshooting and problem-solving skills.
• Ability to follow technical procedures and document completed work.
• Strong willingness to learn cybersecurity, cloud, automation, and compliance technologies.

Role Expectations

The CMMC Engineer is expected to grow into a well-rounded cybersecurity engineer capable of supporting CMMC-aligned environments across multiple technologies.

This is a developmental engineering position. The engineer is not expected to enter the role as a CMMC subject-matter expert or independently design complex CMMC architectures. Instead, the individual will work under the guidance of experienced engineers while progressively developing expertise in CMMC, NIST SP 800-171, Microsoft security technologies, cloud engineering, automation, and cybersecurity.

As technical proficiency increases, the engineer will be expected to take greater ownership of implementations, troubleshooting, automation, and technical control validation while contributing to the continued standardization and scalability of RSM Defense's CMMC engineering capabilities.
