In this role, you will apply systems engineering principles within a digital engineering framework to create, analyze, and maintain system architecture models. You will collaborate with government leads, prime contractors, and cross-functional engineering teams to trace requirements, model behavioral and structural architectures, and support technical baseline reviews.\nWhat You'll Be Doing:\nSystem Modeling & Architecture: Develop and maintain descriptive system models using SysML to capture system behaviors, structure, interfaces, and operational requirements across MDA programs.\nRequirements Traceability: Map system-level and component-level requirements directly to architecture artifacts, ensuring end-to-end traceability, verification matrices, and baseline integrity.\nDigital Engineering Integration: Support the implementation of MDA Digital Engineering initiatives by linking MBSE models with external tools, simulations, and data repositories.\n Technical Baseline Reviews: Assist in preparing and presenting model-centric artifacts for major program milestone reviews (e.g., SRR, PDR, CDR, CCBs).\n Interface & Trade Studies: Conduct architectural trade studies, analyze interface definition documents (IDDs/ICDs), and model system interfaces to identify gaps and resolve integration risks.\nConfiguration & Data Management: Maintain version control and configuration baseline compliance for SysML models in accordance with program data management standards.\nWhat Required Skills You'll Bring:\nSecurity Clearance: Active DoD Secret clearance\nEducation & Experience: Bachelor degree with 7+ years supporting missile defense or large-scale, complex DoD programs.\nTechnical Proficiency:Demonstrated proficiency with SysML (Systems Modeling Language) and core systems engineering frameworks (DoDAF, UAF).\nHands-on experience with industry-standard MBSE modeling tools (e.g., Cameo Systems Modeler / Cameo Enterprise Architect, MagicDraw, Sparx Enterprise Architect).\n\nCommunication: Ability to distill complex system architectures into clear, concise diagrams, technical documentation, and briefings for multidisciplinary stakeholders.\nWhat Desired Skills You'll Bring:\nExperience supporting MDA programs (e.g., Targets and Countermeasures, Ground-Based Midcourse Defense, THAAD, Aegis BMD, or C2BMC).\nOMG-Certified Systems Modeling Professional (OCSMP) certification (Fundamental, Intermediate, or Advanced).\nWorking knowledge of requirement management tools (e.g., DOORS, Cameo Requirements Plugin) and issue-tracking platforms (Jira, Confluence).\nExperience integrating MBSE models with analytical/simulation environments (e.g., MATLAB/Simulink, Python, or OpenMBEE).\nFamiliarity with DoD Systems Engineering processes, CDRLs, and technical baseline governance.","description_format":"text","description_chars":2943,"description_truncated":false,"requirements":{"experience_years_min":7,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":true,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Artificial Intelligence","Machine Learning","Industrial Engineering"],"lifecycle":[{"event":"open","at":"2026-09-11T23:11:43Z"}],"liveness":{"score":68,"band":"ok","label":"Likely open","p_open":1,"p_active":0.759,"p_room":0.9,"age_days":22,"expected_fill_days":42,"reasons":["conf:2","velocity","win:mid"],"computed_at":"2026-09-24T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/apextk-mbse-engineer","json_url":"https://alion.io/job/apextk-mbse-engineer.json","meta":{"generated_at":"2026-09-25T02:42:13Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":2899,"day_limit":5000,"remaining_today":2101,"minute_limit":60,"resets_at":"2026-09-26T00:00:00Z"}}}
