Position title
Multi Discipline Security Specialist - Junior

Job Description:

4LNS is seeking candidates to join a highly successful team that has won and performed over $100 Million of Defense Threat Reduction Agency (DTRA) work around the world for more than 20 years.  This challenging and exciting work will provide you the opportunity to travel CONUS and OCONUS to the most important DoD defense systems and critical infrastructure to ensure the survivability of any threat or attack. This is an exciting opportunity to experience travelling to destinations around the world and protecting mission critical infrastructure.

The Defense Threat Reduction Agency (DTRA), Nuclear Enterprise Support Directorate (NE) performs integrated, multidisciplinary, assessments that assess survivability of critical U.S. and allied national/theater mission systems, networks, architectures, infrastructures, and assets. Blue Team assessments teams aim to ensure continuity to DoD missions and critical infrastructure by assessing the vulnerabilities and survivability of these infrastructure against a broad spectrum of threats including accidents, natural disasters, technological failure, information system attacks, terrorists, radio frequency weapons (RFW), sabotage, and weapons of mass destruction (WMD).

In order to ensure continuity of DoD Missions and to maintain continuous operations of critical infrastructure, it is imperative to have fully functional Blue Teams (1) to conduct assessments; (2) to provide specific SME assistance to Technical Support Projects (TSPs); (3) to provide Design Review assistance; and (4) to provide technical assistance to the Home Team.   The size and skillsets of each team will vary and include those required to execute each mission.  The resource needs of each mission and/or stakeholder requests will be identified and managed by DTRA.

Blue Team assessments include, but are not limited to, examining surveillance operations, physical security, telecommunications (e.g., video, voice and data, commercial and military), information operations (e.g., computer networks, IA tools use, operations security), structural protection and response (to include blast effects modeling and consideration of anti-terrorism/force protection standards), utility subsystems (e.g., power and heating, ventilation, and air conditioning reliability and endurance), weapons of mass destruction protection, emergency operations (e.g., emergency preparedness, fire protection, emergency response, disaster control and recovery, continuity of operations), and electromagnetic protection (e.g., electromagnetic pulse and radio frequency weapon susceptibility, lightning protection).  The Blue Team mission, by necessity, is fluid and requires the teams operating within these environments to be adaptable.


The Multi-discipline Security Specialist responsibilities:

  • - Shall conduct assessments of identified assets and supporting infrastructure to determine vulnerabilities that could lead to risk to mission.
  • - Provide recommendations to reduce the overall risk by preventing or mitigating damage to or destruction of mission-critical systems should a plausible threat be carried out.

  • - Multi-discipline Security Specialist should possess knowledge of all aspects of risk management, security operations, and advanced security technologies.

Required Skills/Qualifications:

  • - Knowledge of the security needs for a wide-variety of mission critical infrastructure to include network and data centers, telecommunications systems, airfields, nuclear weapons systems, forward operating bases, and the defense industrial base.
  • - Experience with DoD Security Directives, including their development and implementation of Army, Navy, Marine Corps, Air Force and Joint DoD Security directives.
  • - Knowledge of all DoD force protection/antiterrorismprograms and requirements.
