• Must demonstrate a strong engineering background supporting high-visibility systems that transmit worldwide, including ships at sea.
• Demonstrated experience producing enterprise architecture artifacts, including logical and physical architecture diagrams, technical design documentation, interface documentation, implementation strategies, engineering design packages, and modernization roadmaps.
• Experience translating operational and mission requirements into enterprise technical architectures and engineering solutions.
• Experience performing architecture trade studies, technical assessments, engineering analyses, and technology modernization initiatives.
• Candidate must hold an IAT II qualified certification (example: Security+).
• Experience with Red Hat Enterprise Linux.
• Working knowledge of DoD, Intelligence Community, and Joint interoperability requirements for National Security Systems.
• Candidate must demonstrate exceptional attention to detail.
• Candidate must possess excellent communication, presentation, and technical writing skills.
• Skilled in developing and maintaining SOPs and TTPs.

Clearance Required

Candidate must have a current Top Secret clearance and be able to obtain SCI clearance.

Desired Qualifications

• Knowledge of the use of C2 messaging in the DoD.
• Experience modernizing legacy National Security Systems (NSS).
• Experience designing enterprise architectures aligned with Zero Trust principles, Identity, Credential, and Access Management (ICAM), Cross-Domain Solutions (CDS), mission assurance, high availability, and resiliency.
• Experience supporting enterprise architecture reviews, technical interchange meetings, engineering review boards, or design reviews.
• Experience with DoDAF or comparable enterprise architecture methodologies is desired.

Key Responsibilities

• Identify and refine mission requirements and coordinate buy-in with key stakeholders.
• Develop enterprise technical architectures and architectural laydowns that translate mission requirements into implementable engineering solutions.
• Produce and maintain enterprise architecture artifacts, including logical and physical architecture diagrams, interface documentation, technical design packages, engineering documentation, and modernization roadmaps supporting OMS and associated National Security Systems.
• Generate feasibility and technical analysis reports upon Government request to assist the Government's decision-making process.
• Perform architecture trade studies and engineering assessments evaluating multiple technical approaches, interoperability impacts, technical risks, lifecycle costs, and modernization strategies.
• Be responsible for project planning and, upon Government approval, project execution. Projects should follow project management best practices.
• Identify system hardware, software, and operational changes to enhance operational efficiency and improve usability on the Organizational Messaging Service (OMS) system.
• Architect and modernize legacy National Security Systems (NSS) messaging capabilities by designing enterprise-level technical architectures that comply with DoD, Intelligence Community, and Joint interoperability standards.
• Ensure architecture alignment with Zero Trust principles, ICAM, Cross-Domain Solutions (CDS), mission assurance, high availability, redundancy, resiliency, and continuity of operations requirements.
• Generate feasibility reports when requested by the COR. Feasibility reports may be in response to operational incidents, administrative priorities, or technology lifecycle. The contractor shall ensure specific requirements, objectives, trade-offs, constraints, technical risks, and implementation considerations are included in the feasibility studies. The contractor shall ensure feasibility studies present multiple approaches to risk analysis, software, hardware, architecture, interoperability, and operational procedure changes. The report shall include estimates of cost, schedule, technical risk, and implementation effort for each recommended approach.
