About the Job

Requirements

  • An active Certified Information Systems Security Professional (CISSP) or Certified Information Security Manager (CISM) certification is required; other relevant certifications such as CCSP or CEH may be considered.
  • A bachelor's degree in computer science, engineering, STEM, information technology, or cybersecurity is required.
  • At least eight years of experience in information security, including at least five years specifically in a lead ISSO or similar leadership capacity on large, complex U.S. government programs.
  • Experience carrying a system through authorization and working within the Risk Management Framework or an equivalent federal authorization framework.
  • Experience closing classes of security findings and explaining the changes made to prevent recurrence.
  • Experience writing or reviewing security documentation that was defended before a government reviewer.
  • Experience running continuous monitoring when the available data is incomplete.
  • Preferred certifications include active CISSP, Project Management Professional (PMP), ISC2 Certified in Governance, Risk and Compliance (CGRC), CISM, CAP, and Security+.
  • An active CBP Background Investigation, a fitness determination at another Department of Homeland Security component, or an active Department of Defense clearance is useful and can shorten the start date.
  • Knowledge of FedRAMP.
  • Knowledge of A-123 audit experience and expertise with governance, risk, and compliance tools such as CSAM.

Responsibilities

  • For the ISSO discipline, own whether assigned systems remain authorized and accurately described.
  • For the ISSO discipline, determine acceptable control implementation, what belongs on a Plan of Action and Milestones (POA&M), and when a change requires a security review before proceeding.
  • For the Senior Security Engineer discipline, own how systems are hardened, monitored, and remediated.
  • For the Senior Security Engineer discipline, determine secure configuration, tooling used by the program, and which risks should be engineered out rather than accepted and tracked.
  • For the Security Engineering Lead discipline, own the security engineering function, including the standards other engineers build against.
  • For the Security Engineering Lead discipline, be accountable when a design encounters a threat or audit finding it did not anticipate.
  • Close security findings at their cause, remediate underlying conditions, trace recurring findings to the build, process, or standard that produced them, and document justified exceptions with compensating controls.
  • Bring security input into designs early enough to influence decisions and communicate requirements and what will pass security review.
  • Maintain an accurate and current view of system security posture, ensure recorded implementations match deployed systems, and escalate material risks while decisions can still be made.
  • Work with network engineers, cloud engineers, field deployment teams, and government security staff.

Desired Qualifications

  • An active CBP Background Investigation and EOD is preferred and qualifies candidates for a $10,000 signing bonus payable after 90 days under standard terms.
  • A fitness determination at another Department of Homeland Security component or an active Department of Defense clearance is advantageous and may shorten the start date.

Cybersecurity and IT services for government

Agile Defense provides IT and cybersecurity services to the U.S. Federal Government, including digital transformation, IT modernization, and a Virtual Security Operations Center (VSOC) to defend against cyber threats. Its services support national security and civilian missions across federal agencies, delivered through various contract vehicles. The company expands its capabilities through acquisitions (IntelliBridge and XOR Security) and focuses on AI-enabled workforce transformation and enterprise IT to enhance government operations. Unlike many suppliers, Agile Defense emphasizes a government-focused portfolio with a multidimensional VSOC and AI-driven workforce upgrades, positioning itself to meet federal security and modernization needs. The goal is to help federal agencies protect data and systems, modernize IT infrastructure, and improve cyber resilience across national security and civilian missions.
