The posting

Join ClearPoint and become part of a team focused on delivering secure environments that support mission-critical work for government and defense organizations. ClearPoint specializes in designing, building, and managing secure facilities and controlled environments that enable partners across the Defense Industrial Base to operate in highly regulated settings.

As part of the ClearSpectrum LLC family of companies, ClearPoint combines enterprise resources with small-business agility to deliver secure infrastructure solutions. Our team supports the development of secure collaboration spaces, classified environments, and mission-enabling facilities that help customers execute critical national security missions.

Your Mission:

You Will Excel in This Role If You Are:

  • Experienced leading RMF/ATO efforts for classified DoD or IC systems
  • Comfortable reviewing and shaping secure system architecture alongside engineers, not just documenting it after the fact
  • Skilled in vulnerability assessment and security testing of live systems
  • Familiar with NIST SP 800-53 and DoD RMF processes at an implementation level
  • Capable of translating security findings into concrete, actionable remediation guidance
  • Comfortable balancing compliance documentation with ongoing hands-on technical engagement
  • Experienced mentoring less experienced security staff

A Day in the Life:

  • Develop and maintain SSP, SAR, and POA&M documentation for RMF accreditation
  • Review system architecture and provide security guidance to engineers during design and development
  • Conduct vulnerability scans and security assessments of the system as it's built
  • Identify security weaknesses and recommend system-level remediation
  • Implement and manage security controls, including identity/RBAC, audit logging, and encryption
  • Track and drive remediation of findings identified during security assessment
  • Mentor junior security staff and provide technical guidance

What We Are Expecting From You:

  • Active TS/SCI with Polygraph clearance; U.S. citizenship
  • Bachelor's degree in Computer Science, Software Engineering, or related field (4 years of experience may substitute), plus 8 years of experience in information systems
  • 5–8 years of experience as an ISSE or Cybersecurity Engineer
  • Proficiency with networking, firewalls, and security monitoring tools
  • Knowledge of operating systems, system security design, risk analysis, and security policies
  • Experience with NIST Risk Management Framework (RMF) or DoD 8500 series compliance
  • Experience reviewing and shaping secure system architecture alongside development teams
  • Experience conducting vulnerability assessments and security testing

Nice to Have:

  • Experience embedding security into CI/CD pipelines and DevSecOps workflows
  • Familiarity with container and cloud security tooling
  • Experience with automated security scanning (SAST/DAST) as part of the development lifecycle
  • Experience with cryptography, encryption technologies, and application security
  • Experience with penetration testing
  • Experience with physical security or facility accreditation practices, such as ICD 705 or similar frameworks

ClearPoint is committed to delivering secure, compliant environments that enable our partners to operate effectively in mission-critical settings. We value a culture of collaboration, accountability, and operational excellence while empowering our employees with opportunities to grow and contribute to meaningful work.

Our Core Values—Honesty, Integrity, Loyalty, Fairness, Respect, Responsibility, and Accountability—guide how we operate and how we support our customers and partners. If this position is not the right fit, we encourage you to explore additional opportunities across the ClearSpectrum family of companies or reach out to our recruiting team at [email protected]. ClearPoint is an equal opportunity employer.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
