JSE Mission Modeler

About the Role

FlightSafety Defense Corporation is gearing to become a recognized integration partner and solution provider for the U.S. Air Force and U.S. Navy in the Joint Simulation Environment (JSE) and Simulator Common Architecture Requirements and Standards (SCARS) ecosystem. The JSE Mission Modeler is a key contributor within the JSE/SCARS line of efforts, responsible for designing, building, and executing military mission scenarios that support large-force virtual training and mission rehearsal within the JSE Technical Baseline (JTB). This role directly supports FSI Defense's pursuit of modular and scalable simulation architectures capable of supporting 100+ player exercises within a shared synthetic battlespace.

The right candidate brings hands-on experience with military scenario authoring, constructive simulation frameworks, and the operational knowledge needed to produce tactically credible training events across multiple classification levels and platform types.

Responsibilities

• Design and develop mission scenarios for large-force virtual training exercises within the JSE synthetic battlespace, integrating blue air, red air, constructive forces, and environmental conditions using JSE-compatible tools, behavior scripts, and constructive simulation frameworks.
• Author and maintain scenario behavior files, Lua-based launching scripts, mission planning configurations, and scenario control logic in accordance with JSE Platform Package (JPP) standards.
• Coordinate with JSE GRID services — including entity state management, sensor services, weapon interactions, and line-of-sight services — to produce high-fidelity, repeatable training events.
• Work with Government program offices, aircrew subject matter experts (SMEs), and simulation engineers to translate operational training requirements into executable synthetic environment scenarios.
• Support scenario validation events at JSE facilities and participate in test events at government sites such as JITTC-E (Elmendorf AFB), NAWDC (Fallon NAS), and Digital Test and Training Range (DTTR) locations.
• Support debrief analysis and contribute to the development and maintenance of scenario libraries across multiple mission profiles, platform types, and force ratios, with attention to scalability for multi-site training environments and secure multi-level security (MLS) operations.
• Contribute to scenario documentation, support Requirements Verification Report (RVR) activities, and maintain traceability between scenario design artifacts and applicable JSE and SCARS standards.
• Travel to Government test events, contractor facilities, and operational training sites as required.

Requirements

• Bachelor's degree in aerospace engineering, systems engineering, operations research, computer science, or a closely related technical discipline; advanced degree preferred.
• 5 or more years of experience in military mission scenario development, constructive simulation, or distributed synthetic environment operations in a DoD context.
• Demonstrated hands-on experience with military scenario authoring tools and constructive simulation frameworks (e.g., AFSIM, JSAF, EADSIM, OneSAF, NGTS, or equivalent).
• Familiarity with distributed simulation protocols including HLA, DIS, or TENA, and experience connecting scenario entities to a networked synthetic environment.
• Understanding of JSE architecture, GRID services, and the JSE Platform Package (JPP) structure, including behavior files, Lua scripting, and entity state message formats.
• Operational knowledge of U.S. Air Force or U.S. Navy aviation tactics, techniques, and procedures (TTPs), sufficient to author tactically credible training scenarios.
• Experience supporting large-force exercises (LFEs) or virtual training events with 50 or more players in a live, virtual, or constructive (LVC) environment.
• Strong technical writing and communication skills, with experience producing scenario documentation, test plans, and after-action reports (AARs).
• Active Secret clearance; ability to obtain Top Secret/SCI clearance.

Preferred Qualifications

• Direct experience working within the JSE ecosystem, including familiarity with GRID services, the Government Simulation Interface (GSI) SDK, and JSE Technical Baseline (JTB) components.
• Experience with multi-level security (MLS) simulation environments and cross-domain scenario operations.
• Familiarity with SCARS Increment 5 standards, including the SCARS Architecture Standard and DevSecOps Process Standard.
• Experience with the Weapon System Trainer Common Environment (WSCE) and standard munitions modeling workflows.
• Proficiency in Lua, Python, or C++ for scenario scripting, automation, and data analysis.
• Familiarity with MBSE methodologies and SysML-based modeling tools used in JSE program documentation.
• Prior experience supporting Government program offices, including AFLCMC, PMA-205, or JSE Program Office activities.
• Experience with debrief system integration and training effectiveness analysis.

Why This Role

The JSE Mission Modeler sits at the intersection of operational military knowledge and advanced simulation engineering — a combination that is rare and highly valued in the JSE ecosystem. This individual will directly shape the quality and tactical fidelity of training scenarios that FSI Defense delivers as part of the DIU All Players initiative and future JSE-connected programs. As FSI Defense establishes itself as a recognized integration partner for the USAF and Navy, the Mission Modeler will have early visibility into some of the most strategically significant training system programs in the Department of Defense.
