Principal MS&A Engineer

• Lead mediumtolargescale AFSIM mission modeling efforts for United States Air Force (USAF) and Department of War (DoW) customers.
• Architect highfidelity simulation environments capturing multidomain interactions including C5ISRT, longrange kill chains, collaborative autonomy, integrated air defenses, and space mission resiliency.
• Design and execute modeling of spacebased kinetic and nonkinetic conflict scenarios; define modeling fidelity, scope, methodology, and data sourcing.
• Lead operational modeling projects, ensuring consistent methods, validated models, and quality deliverables across multiple study teams.
• Build 3D models, interactive environments, and visualization products to support mission planning, CONOPS development, and seniorlevel decision briefings.
• Develop and refine system and systemofsystems architectures using advanced simulation to inform resiliency, survivability, and performance trade studies.
• Conduct missionlevel, engagementlevel, and systemlevel analysis using AFSIM, government tools, and commercial platforms.

• Independently interface with senior government representatives to refine tasking, present results, define modeling requirements, and provide technical recommendations.
• Attend summits, conferences, and crossagency meetings to communicate technical findings and maintain awareness of emerging USAF and DoW modeling needs.
• Ensure tasklevel products align with overall program strategy, customer timelines, and required analytic rigor.

• Serve as tasking lead and technical mentor for modeling teams of 2-3 engineers per study; coordinate efforts across CONOPS, MBSE, architecture, and M&S teams.
• Manage daytoday work assignments for project leads; balance workload and tasking across multiproject environments.
• Ability to supervise teams of 10+ direct reports and multiple subteams, providing performance feedback, career growth guidance, and professional development.
• Act as hiring manager for M&S teams, driving talent strategy, interviews, selection, onboarding, and longterm workforce planning.
• Provide training, career guidance, and crossfunctional development opportunities for M&S personnel and technical contributors.
• Lead enterprise workforce development initiatives including AFLCMC/EB, OUSW R&E and DoW.

• Create detailed 3D facility models and interactive simulation environments for mission planning, training, and contingency response.
• Conduct facility risk analysis, infrastructure assessments, and forceonforce modeling using government and commercial simulation tools.
• Automate simulation workflows using scripting languages (C#, Python, JavaScript, MATLAB) to improve analytical efficiency.

• Expert proficiency with AFSIM and advanced missionlevel modeling of multidomain systems.
• Strong expertise creating and validating models and simulations across space, air, and integrated defense environments.
• Ability to break complex operational problems into structured analytic components, prioritize tasks, and assign technical resources appropriately.
• Recognized subjectmatter expertise in C5ISRT, system architecture definition, and mission engineering.
• Ability to anticipate technical risks, propose mitigation strategies, and maintain analytic integrity across diverse M&S frameworks.
• Strong communication skills enabling clear delivery of complex simulation results to senior external customers.
• Experience managing and mentoring teams of junior engineers and analysts.

• Bachelor's or Master's degree in engineering, physics, or related discipline.
• 8+ years of experience developing multidomain, space, weaponsystem, and missionlevel M&S.
• Experience across multiple simulation frameworks (i.e. AFSIM, ESAMs, CFAM).
• Experience supporting multiple USAF and DoW customers including AFLCMC, AFRL, OUSW R&E, SCO, and DARPA.
• TS/SCI clearance required; SAP eligibility desired.
