Mid-Level Information System Security Officer (ISSO)

Dragonfli Group is a cybersecurity and IT consulting firm providing services to federal agencies and Fortune 100 enterprises. Headquartered in Washington, DC, Dragonfli supports clients in securing mission-critical systems across on-site, hybrid, and fully remote environments.

Dragonfli Group is seeking a Mid Information System Security Officer (ISSO) to own the security posture of assigned systems on a multi-year cybersecurity program for a large federal agency. You will advise on architecture, authorization boundaries, and risk decisions, and you will lead control compliance and assessment readiness for your systems, maintaining the System Security Plan and other key artifacts and coordinating audits and assessments end to end. You will run continuous monitoring and reporting, define the metrics that make posture legible to stakeholders, and escalate material risks with a recommended course of action. You will also drive vulnerability remediation and POA&M corrective actions, including the harder calls around exceptions, compensating controls, and risk acceptances. This role suits an ISSO with roughly 4 years of experience who is ready to be the accountable security voice for a system rather than a supporting one.

This is a multi-year contract position involving a large US federal agency. Candidates with previous federal contracting experience are preferred. U.S. Citizenship or Permanent Residency is required. If hired, all work related to this role must be performed within the continental U.S.

This position is fully remote. The agency's Rules of Behavior and Telework Policy apply to all contractor personnel and require, among other things, that laptop cameras be turned on and that staff remain visible on camera during all meetings.
