Our teams are at the frontier of the Nation's most complex and rewarding challenges. Join our team.
Barbaricum supports NSWC Crane with advanced modeling, simulation, and mission analysis capabilities that inform DoD platform architecture, system integration, and test and evaluation activities. Our teams deliver physics-based analysis that complements MBSE efforts by transforming authoritative SysML-based system models into executable mission-level simulations and actionable analysis products across complex, multi-domain operational environments.
We are seeking an AFSIM Simulation Engineer to develop and execute mission-level and kill-chain simulations that consume MBSE-defined system architectures, interfaces, and mission threads to assess hardware-centric DoD platforms and integrated mission systems.
The Role
The AFSIM Simulation Engineer develops, executes, and analyzes physics-based mission simulations using the Advanced Framework for Simulation and Integration Modeling (AFSIM). This role supports mission effectiveness assessments, experimentation, and Live, Virtual, and Constructive (LVC) events by implementing MBSE-derived SysML views-including requirements, functional threads, physical architectures, and interfaces-as AFSIM inputs to evaluate sensor-to-shooter kill chains and operational effects, including EMSO-relevant influences.
Responsibilities

• Develop, modify, and execute AFSIM models derived from MBSE SysML artifacts, including mission threads, functional flows, system architectures, and interface definitions
• Analyze blue vs. red kill chains, system interactions, and mission-level effects across integrated sensor, shooter, and command elements
• Translate MBSE handoff artifacts (requirements allocations, activity diagrams, block definitions, internal block diagrams) into executable AFSIM entities, behaviors, and interactions
• Integrate sensor, RF, EW, weapon, and platform models consistent with MBSE-defined system boundaries, interfaces, and architectural assumptions
• Support experimentation, test events, and LVC exercises focused on validating system architectures, mission threads, and kill-chain performance
• Conduct verification and validation of AFSIM models against MBSE-defined assumptions, constraints, and system definitions
• Perform statistical and analytical assessments of mission outcomes and kill-chain performance drivers, producing analysis products traceable to system design and architecture decisions
• Collaborate with MBSE, LVC, and other modeling and simulation teams to maintain digital thread continuity from SysML models through AFSIM simulations to analysis reports and T&E artifacts

Required Qualifications

• Bachelor's degree in Engineering, Physics, Operations Research, or related technical field
• Active DoD Secret (Top Secret/SCI preferred)
• 5+ years of modeling and simulation experience supporting system-level or mission-level analysis
• Hands-on experience developing and executing AFSIM models
• Strong understanding of mission-level analysis, system architectures, and kill-chain dynamics
• Ability to interpret and analyze large simulation datasets and trace results back to system requirements and architecture drivers

Desired Qualifications

• Experience supporting DoD platforms or hardware-centric mission systems within an MBSE-driven development environment
• Experience executing sensor-to-shooter or effects-based kill-chain analysis tied directly to system architecture trades
• Experience supporting DoD test, evaluation, or experimentation activities using MBSE-informed scenarios and architectures
• Programming experience in Python, C++, or MATLAB
