MOSA Architect & Systems Integration Lead - Clearance Required

Modular Architecture & MBSE: Translate complex Army requirements into modular solutions using SysML. Develop model libraries and profiles to serve as the Authoritative Source of Truth for system-of-systems.

• Interface Control & Interoperability: Identify logical boundaries and system interfaces to enable seamless component interchangeability.
• Standards Implementation & Policy: Apply open standards (e.g., SOSA, DoDAF, and UAF) to practical hardware/software builds. Draft and refine DoD systems engineering guidance and technical criteria for MOSA implementation across Programs of Record.
• Digital Engineering Lifecycle: Design and manage digital threads, integrating MBSE with Product Lifecycle Management and DevSecOps stacks.
• Business Analysis: Conduct trade-off studies and "what-if" assessments to balance modularity benefits against rapid deployment needs; defend MOSA business cases for milestone decisions.
• Validation and Verification: Support the development of technical assessment frameworks and performance metrics to evaluate MOSA compliance throughout the systems engineering V-model.
• Stakeholder Engagement: Facilitate or engage in technical exchange meetings, potentially with various PAEs to drive digital convergence.

• BS/MS in Systems, Electrical, or Computer Engineering (or equivalent technical industry experience).
• 10+ years in Systems Engineering or Data Architecture with a focus on Architecture Patterns (Microservices, SOA, REST).
• Ability to lead the development of innovative approaches in modernizing systems engineering practices.
• Deep familiarity with ISO/IEC 15288 and DoD 5000 series acquisition policies.
• Proven ability to integrate requirements management with architectural models to ensure end-to-end traceability.
• Experience advising data rights strategies to ensure long-term competitive sourcing and avoid vendor lock-in.
• Knowledge of conformance tools and verification suites to ensure modularity throughout the Systems Engineering V-model.
• Experience with MBSE tools (e.g., No Magic Cameo, IBM Rational Rhapsody, Sparx Enterprise Architect)., * Experience authoring or contributing to capability briefs or white papers on Digital Continuity and Mission Engineering.
• Experience with relevant hardware design and implementation (e.g., FPGA design, VHDL) and system simulation tools (e.g., Ansys ModelCenter, STK, or MATLAB/Simulink) to support Digital Engineering and MOSA compliance.
• Knowledge and/or hands-on experience with SOSA, CMOSS or FACE frameworks within a DoD environment program.
• INCOSE CSEP/ESEP or DAWIA Level III Certification in Systems Engineering.
• Experience working within the Scaled Agile Framework (SAFe) to manage product backlogs for complex system designs.
• Active Secret.

Target salary range: $123,000 - $211,000. Final compensation will be determined by a variety of factors including but not limited to your skills, experience, education, and/or certifications.
