[Hiring] Lead CMMC Assessor @Sentinel Blue

Role Description

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.

A day in the Lead CCA role:

• Start the day meeting with your assessment team to review assigned practices and check their notes for completeness, accuracy, and consistency.
• Mentor junior assessors, coaching them on how to ensure the environment is assessed and documented appropriately.
• Review client documentation in preparation for both Phase 1 and Phase 2 activities.
• Lead calls with the client to confirm assessment scope, walk them through findings as they emerge, and verify that required evidence is accurate and relevant.
• Make the final call on outcomes — determining whether each practice is scored MET or NOT MET, and ultimately whether the organization achieves certification.

Qualifications

• 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.
• Strong working knowledge of NIST SP 800-171, NIST SP 800-172, and the CMMC Assessment Process (CAP).
• 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.

Requirements

• Hands-on assessment experience in Microsoft GCC High or Azure Government environments.
• Familiarity with DFARS 252.204-7012, DFARS 7019/7020, and broader DIB compliance requirements.
• Prior experience leading or supervising assessment teams.
• Additional certifications (CISSP, CISA, Lead CCA).
• Bachelor's or Master's degree in Cybersecurity, Information Systems, Computer Science, or a related field.

Benefits

• Fully paid individual healthcare, vision and dental insurance for the employee.
• Paid certification and training opportunities.
• Three weeks of paid vacation + 10 paid holidays.
• A supportive environment with a focus on keeping healthy work-life balance.
• Retirement benefit (401k) with company match.
