K2Share is seeking a CDM Engineer to support a federal health-sector client. In this role, you will implement, operate, and enhance the Continuous Diagnostics and Mitigation (CDM) program across a complex hybrid environment spanning on-premises, cloud, and third-party systems. Your work will improve enterprise visibility, strengthen cybersecurity posture, and help reduce operational risk by driving effective asset, configuration, and vulnerability management.

You'll support a large, hybrid enterprise environment of FIPS 199 Low and Moderate systems spanning on-premises, cloud, and third-party hosted services. 

This position is remote first, with periodic on-site support in the Washington, DC metropolitan area as directed, and is contingent upon contract award. 

About You

You are a cybersecurity professional who thrives on building and improving enterprise security operations. You understand that effective vulnerability management is more than running scans. It requires collaboration, analysis, prioritization, and continuous improvement to help organizations make informed risk decisions.

You are comfortable working across hybrid environments, partnering with technical teams, system owners, and security stakeholders to improve visibility and reduce cyber risk. You enjoy solving complex operational challenges, communicating technical findings clearly, and helping organizations mature their continuous monitoring capabilities in alignment with federal cybersecurity standards.

Whether responding to emerging vulnerabilities, improving scanning infrastructure, or supporting ongoing authorization efforts, you bring a proactive mindset, technical expertise, and a commitment to protecting mission-critical systems.

Your Impact

As the CDM Engineer, you will play a key role in operating and advancing the client's Continuous Diagnostics and Mitigation program. You'll ensure security teams and system owners have the visibility and actionable intelligence needed to identify, prioritize, and remediate vulnerabilities across the enterprise.

In this role, you will:

• Implement, operate, and maintain Continuous Diagnostics and Mitigation (CDM) capabilities that strengthen enterprise cybersecurity posture.
• Maintain the CDM scanning infrastructure supporting client systems across on-premises, cloud, and hybrid environments.
• Partner with technical stakeholders to expand and mature CDM capabilities as the environment evolves through modernization and cloud adoption.
• Support the transition to  Ongoing Authorization by providing continuous monitoring and security visibility.
• Deliver continuous asset visibility and improve detection of vulnerabilities, configuration issues, unmanaged assets, and unauthorized software or hardware.
• Manage enterprise vulnerability scanning infrastructure, including credentialed scanning across systems, devices, and applications.
• Analyze vulnerability scan results, prioritize risk, and provide actionable remediation recommendations.
• Monitor the CISA Known Exploited Vulnerabilities (KEV) Catalog and other authoritative guidance to support timely remediation and compliance with applicable Binding Operational Directives.
• Support enterprise asset inventory, configuration monitoring, and compliance reporting activities.
• Collaborate with the client and department stakeholders, system owners, administrators, and technical teams to improve security operations, optimize tools, and support incident response activities.
• Contribute data and analysis supporting executive cybersecurity reporting, including weekly CIO dashboards and ad hoc vulnerability reports.
• Produce and maintain required CDM deliverables, including CDM Scan Results on the DHS-defined periodicity of no less than every three days, CDM Mitigation Procedures documenting mitigation steps and end-user mitigation activities when requested, and compliance reporting. 

• Bachelor's degree in Computer Science, Information Systems, Cybersecurity, or a related field, or equivalent professional experience.
• Five or more years of experience supporting enterprise vulnerability management, Continuous Diagnostics and Mitigation (CDM), or security operations.
• Experience administering enterprise vulnerability scanning platforms and supporting credentialed  scanning across large hybrid environments.
• Working knowledge of the DHS Continuous Diagnostics and Mitigation (CDM) program, including asset management, configuration monitoring, reporting, and CDM dashboard concepts.
• Familiarity with FISMA, FIPS 199, NIST SP 800-53 Rev. 5, Risk Management Framework (RMF), and continuous monitoring supporting Ongoing Authorization.
• Experience managing vulnerabilities in accordance with the CISA Known Exploited Vulnerabilities (KEV) Catalog and applicable CISA Binding Operational Directives.
• Strong analytical, communication, and collaboration skills with the ability to work effectively across technical and customer organizations.
• Ability to satisfy federal background investigation requirements and complete required onboarding before receiving system access.
• U.S. work authorization.

Preferred Qualifications

• Professional cybersecurity certification such as CISSP, CompTIA Security+, CySA+, or GIAC certifications (GCIH, GCIA, GMON).
• Tenable platform certification (Tenable Certified Security Center Specialist or Nessus equivalent)
• Experience with enterprise vulnerability management tools such as Tenable.sc, Nessus, and related asset discovery, SIEM, EDR, or configuration management platforms.
