• Support secure configuration and hardening efforts using applicable benchmarks, baselines, STIGs, CIS guidance, or organizational security standards.
• Maintain inventories of systems, applications, interfaces, components, software, and security-relevant assets where required.
• Support incident response coordination, security investigations, and reporting activities as required.
• Track continuous-monitoring requirements, recurring assessments, security metrics, control evidence, and remediation status.
• Identify cybersecurity risks and communicate technical findings, impacts, recommendations, and remediation priorities to technical and program stakeholders.
• Assist with development and maintenance of cybersecurity policies, procedures, standards, runbooks, and governance documentation.

Required Qualifications:

• CompTIA Security+
• 5+ years of cybersecurity, information assurance, information security, GRC, system administration, cloud, infrastructure, or related IT experience.
• 3+ years of hands-on experience supporting information-system security, compliance, RMF, security controls, or vulnerability-management activities.
• Strong understanding of cybersecurity risk management, security controls, continuous monitoring, vulnerability management, and remediation processes.
• Experience developing or maintaining System Security Plans, security-control documentation, risk assessments, POA&Ms, control evidence, or comparable compliance artifacts.
• Working knowledge of NIST 800-53, NIST Risk Management Framework, NIST Cybersecurity Framework, or comparable security-control frameworks.
• Experience reviewing vulnerability scans, security findings, configuration weaknesses, and remediation activities.
• Experience working with vulnerability-management tools such as Tenable, Qualys, Microsoft Defender, Rapid7, or comparable platforms.
• Understanding of identity and access management, privileged access, network security, logging, encryption, configuration management, and system-hardening principles.
• Ability to evaluate technical implementations against cybersecurity and compliance requirements.
• Experience supporting security assessments, audits, continuous monitoring, evidence collection, or authorization activities.
• Ability to communicate security risks, findings, remediation requirements, and technical recommendations to engineering and program stakeholders.
