About The Position

Sentinel Blue is hiring a Lead CMMC Assessor (LCCA) for our Radar team. This role leads formal CMMC Level 2 assessments for organizations in the defense industrial base pursuing certification. This role sits within Radar, our C3PAO assessment and compliance practice, and operates independently from Sentinel Blue's managed services delivery lines to preserve assessment integrity and objectivity. This is not a delivery or remediation role. You will be planning and leading formal assessments, evaluating evidence against NIST SP 800-171 practices, managing assessment teams, and producing defensible findings that clients and the Cyber-AB can rely on. This is a full-time position that is fully remote. This position may require access to technology, technical data, or information that is subject to U.S. export control laws and regulations. Employment in this position is contingent upon either verification of U.S. person status as defined under applicable export control regulations (which includes U.S. citizens, lawful permanent residents, and certain protected individuals such as refugees and asylees) or the ability to obtain any required export authorization. The company reserves the right not to apply for an export license and to decline to proceed with any applicant on that basis. All qualified applicants will receive consideration for employment without regard to citizenship status, national origin, or immigration status.

Lead Certified CMMC Assessor (LCCA) credential in good standing with the Cyber-AB with approved Tier III clearance.
Prior experience as a CMMC Assessor, consultant or IT Auditor.

Experience evaluating SSPs, POA&Ms, and technical evidence across IT environments, including cloud environments.
Excellent written communication skills — assessment findings must be precise and defensible.
Ability to work independently and manage multiple concurrent assessment engagements.
Eligible to work with defense industrial base clients; U.S. citizenship may be required depending on client contract terms.
