  • Understanding of the MITRE ATT&CK Framework and its application to threat hunting.
  • Experience working with vulnerability management programs in compliance-driven environments.
  • Clear and concise technical writing skills, with the ability to produce documentation suitable for audits and assessments.

Preferred Qualifications:
  • Experience supporting, maintaining, or engineering for a FedRAMP-authorized system.
  • Experience working with incident response.
  • Background in generating SSPs, POA&Ms, ConMon evidence, or system architecture documentation.
  • Automation experience related to compliance workflows, evidence gathering, or configuration drift detection.
  • Certifications such as Security+, CySA+, CASP+, CCSP, CISSP, or related.
  • Secret Clearance or above.

Additional Information
  • Occasional off-hours support may be required for assessments or critical maintenance.
  • Background check required; clearance not required unless tied to a specific project.
