Digital Architecture & Modeling Engineer
Peraton · Herndon, VA, US
About this role
## Digital Architecture & Modeling Engineer ### Overview Peraton is seeking an experienced **Digital Architecture & Modeling Engineer** to support the modernization of the **Federal Aviation Administration (FAA) National Airspace System (NAS)** under the **BNATCS** program. This role combines **Enterprise Architecture**, **Model-Based Systems Engineering (MBSE)**, and **Modeling, Analysis & Simulation (MA&S)** into a unified, model-centric discipline. You will develop and maintain the **Digital NAS Architecture (DNA)**—an authoritative, model-based representation of the NAS that connects mission needs, operational concepts, requirements, capabilities, systems, services, interfaces, infrastructure, verification evidence, and operational performance. ### Key Responsibilities - Develop and maintain the **Digital NAS Architecture (DNA)** for current-state, transition-state, and target-state NAS architectures. - Apply **UAF, SysML, DoDAF concepts, and MBSE practices** using **Cameo** and **Teamwork Cloud** to model NAS capabilities, missions, operational activities, performers, systems, services, interfaces, information exchanges, infrastructure, and dependencies. - Create **model-based CONOPS** where operational activities, scenarios, mission threads, performers, information exchanges, constraints, assumptions, and supporting architecture are maintained as authoritative model elements. - Generate **DoDAF/UAF architecture views, CONOPS content, interface descriptions, architecture descriptions, matrices, reports**, and other engineering products from the authoritative model using standardized queries/views/templates. - Develop and maintain **mission threads** connecting operational outcomes to capabilities, activities, systems, functions, interfaces, network/infrastructure services, requirements, verification evidence, and lifecycle artifacts. - Build enterprise and **system-of-systems architectures** across the heterogeneous NAS environment (OT, enterprise IT, telecommunications, networks, edge computing, data platforms, cybersecurity, automation, hybrid/cloud infrastructure). - Establish architecture principles, patterns, reference architectures, modeling conventions, reusable libraries, taxonomies, and metamodel extensions. - Perform architecture analysis to identify dependencies, gaps, interface conflicts, integration risks, interoperability concerns, single points of failure, and mission impacts. - Apply simulation and analytical models (e.g., performance modeling, capacity analysis, discrete-event simulation, sensitivity analysis, Monte Carlo) as needed. - Conduct **model-based trade studies** and analysis of alternatives using architecture relationships, requirements, scenarios, simulation results, cost/risk, and mission impacts. - Support virtual integration and system-of-systems analysis to evaluate interactions among independently developed NAS components. - Establish and enforce **model governance** (ownership, configuration management, baselines, branching/version control, validation criteria, model pedigree, authoritative-element ownership, reuse). - Develop reusable enterprise model libraries for common NAS concepts (systems, facilities, interfaces, network/infrastructure services, security constructs, cloud services, operational performers, etc.). - Integrate architecture models with requirements in **Jama Connect** to maintain traceability from mission needs through architecture, implementation, verification, and validatio
