The Architecture Analysis Department researches, develops, and applies advanced technologies in the following Systems Engineering areas:

• Model-Based System Architecting
• Architecture Analysis
• Digital Engineering Transformation Architecture Analysis enables digital transformation by linking stakeholder needs, operational concepts, and engineering data into an integrated digital thread.

The department applies model-based system architecting to define and evolve system structures, interfaces, behaviors, and dependencies for complex systems. The department also delivers architecture analysis through trade studies and assessments of performance, risk, and system interactions to support sound design and investment decisions.

Roles & Responsibilities: The Architecture Analysis Department is seeking a Senior Systems Engineer to support government sponsors in architecting, analyzing, and advancing complex mission and enterprise systems across evolving national security environments. The selected candidate will lead the application of Model-Based System Architecting (MBSA), Model-Based Systems Engineering (MBSE), Architecture Analysis, and Digital Engineering methods to develop, evaluate, and evolve system architectures that enable informed engineering, acquisition, and investment decisions.

Working collaboratively across technical, operational, acquisition, and programmatic stakeholders, the candidate will translate mission needs into integrated architectural solutions, engineering analyses, digital engineering artifacts, and actionable recommendations that improve mission outcomes and enable digital transformation through an authoritative digital thread.

• Apply systems engineering, model-based systems architecting, and architecture analysis principles across the system lifecycle, including mission analysis, concept development, architecture definition, requirements development, integration planning, verification, validation, deployment planning, and technical transition activities.
• Develop and maintain operational, functional, logical, physical, and enterprise architecture products that capture stakeholder needs, mission objectives, system behaviors, interfaces, dependencies, and implementation considerations for complex systems and systems-of-systems.
• Apply Model-Based Systems Engineering (MBSE), Model-Based Systems Analysis (MBSA), and Digital Engineering methods to develop and maintain digital engineering artifacts that establish traceability among stakeholder needs, operational concepts, architectures, requirements, interfaces, constraints, analyses, and verification activities within an integrated digital thread.
• Perform architecture analyses, trade studies, mission engineering assessments, and capability gap analyses to evaluate alternative architectures, operational concepts, emerging technologies, and system design options using qualitative and quantitative methods.
• Collaborate with sponsors, engineers, and multidisciplinary teams to elicit, analyze, document, and validate mission, operational, functional, interface, security, and performance requirements while supporting alignment across stakeholder organizations.
• Support requirements management, interface management, architecture governance, and configuration management activities to maintain consistency, quality, and traceability across engineering products and digital artifacts.
• Provide technical analyses and recommendations to government sponsors and program teams supporting architecture development, Digital Engineering implementation, system modernization, technology insertion, and engineering decision-making.
• Support acquisition planning and execution through contributions to Statements of Work (SOWs), Statements of Objectives (SOOs), Performance Work Statements (PWSs), architecture requirements, evaluation criteria, technical evaluation plans, and technical assessments.
• Develop and communicate technical products including architecture descriptions, engineering analyses, trade study results, Digital Engineering artifacts, technical briefings, and recommendations for technical and management audiences.
• Research, evaluate, and apply emerging approaches in model-based systems architecting, architecture analysis, Digital Engineering, mission engineering, data analytics, artificial intelligence, and related technologies to improve sponsor solutions.
• Contribute to team success through technical collaboration, knowledge sharing, and continuous professional development while building expertise in systems architecture, engineering analysis, and Digital Engineering practices.

Basic Qualifications

• Typically requires a minimum of 5 years of related experience with a Bachelor's degree; or 3 years and a Master's degree; or a PhD with relevant experience who can immediately contribute at this job step; or equivalent combination of related education and work experience.
• Experience applying systems engineering practices to complex technical, operational, or mission-focused systems
• Experience with system design, system architecture modeling, requirements development, interface analysis, integration planning, verification and validation, and technical documentation
• Familiarity with both MBSE and traditional systems engineering approaches, including requirements analysis, functional decomposition, interface control, trade studies, risk analysis, technical reviews, and engineering decision support
• Ability to develop or review architecture products, requirements specifications, trade studies, technical plans, acquisition artifacts, and engineering recommendations
• Ability to work directly with government sponsors, program managers, technical teams, acquisition stakeholders, and mission users
• Strong analytical, verbal, and written communication skills, including the ability to define ambiguous problems, structure technical options, and brief technical concepts to both technical and non-technical audiences
• Ability to work both collaboratively and independently in a dynamic sponsor environment
• This position requires a Top-Secret Clearance
• Per the U.S. Government's eligibility requirements for a clearance, U.S. Citizenship is required.
• This position has an on-site requirement of 4 days a week on-site

Preferred Qualifications

• Experience applying Model-Based Systems Engineering (MBSE), Model-Based Systems Architecting (MBSA), and Digital Engineering methods using SysML and modeling tools such as Cameo, MagicDraw, Rhapsody, Sparx EA, or similar platforms.
• Experience developing and maintaining SysML models and architecture artifacts, including block definition diagrams, internal block diagrams, activity diagrams, sequence diagrams, state machine diagrams, requirements diagrams, parametric diagrams, and allocation relationships.
• Experience developing, documenting, or analyzing system, enterprise, or mission architectures using architecture frameworks such as DoDAF, UAF, TOGAF, or similar methodologies, including operational, functional, logical, physical, interface, and data architecture viewpoints.
• Experience performing architecture analyses, trade studies, mission thread analyses, capability assessments, technology evaluations, or engineering analyses to assess system performance, interoperability, resiliency, technical risk, affordability, and mission effectiveness.
