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.
