Defense Contractor Physics Jobs in Indiana (NOW HIRING)

Iron Will Ventures is a cleared defense small business supporting the nation's highest-priority hypersonic flight test, missile defense, and launch operations missions. We deliver practitioner-grade technical, program, and acquisition support to DoW customers across the enterprise — including TRMC, MDA, JHTO, and the missile enterprise community.

Iron Will Ventures (IWV) seeks a Modeling & Simulation Engineer to support hypersonic and strike weapon system development, test planning, and analysis at NSWC Crane. The successful candidate will build and execute engagement- and engineering-level models — principally AFSIM and 6-DOF trajectory simulations — to inform flight test design, performance assessment, and weapon system integration decisions for DoD sponsors including OUSD(R&E)/TRMC, JHTO, and Navy program offices.

• Develop, modify, and execute AFSIM scenarios and platform/sensor/weapon models to support mission-level trade studies, campaign analysis, and capability gap assessment.
• Build and validate 6-DOF flight dynamics models for hypersonic and tactical missile configurations; support aero database integration, GNC model insertion, and Monte Carlo dispersion analysis.
• Generate trajectory products supporting flight test planning: nominal and dispersed trajectories, footprint and debris analysis inputs, range safety data packages, and instrumentation/coverage assessments.
• Perform post-flight reconstruction and model validation against telemetry and range-collected data; document deltas and recommend model updates.
• Support digital mission engineering workflows — model configuration control, data standards, automation of run matrices, and integration of M&S products into government decision artifacts.
• Produce technical documentation, analysis briefs, and quick-turn responses for government leadership.
• Coordinate with prime contractors, test ranges, and government technical leads; represent IWV in working groups and technical interchange meetings.

• Ability to Obtain a DoD Secret clearance (TS/SCI eligible preferred).
• Bachelor's degree in Aerospace, Mechanical, or Electrical Engineering, Physics, or Applied Mathematics.
• 5+ years of hands‑on M&S experience in a DoD or defense‑industry environment.
• Demonstrated AFSIM proficiency — scenario construction, model development, and results analysis (not solely end‑user operation).
• Demonstrated 6-DOF simulation experience for missiles, launch vehicles, or hypersonic vehicles.
• Working proficiency in Python and/or MATLAB for data reduction, automation, and visualization.
• Ability to work on‑site at NSWC Crane and travel as required.

• Active DoD Secret clearance (TS/SCI eligible preferred).
• Experience supporting hypersonic flight test programs (MACH‑TB, MACH‑XL, CPS, LRHW, ARRW, or equivalent).
• AFSIM plugin/extension development in C++.
• Familiarity with range safety analysis, flight termination, and launch approval processes.
• Experience with aero prediction and trajectory tools (Missile DATCOM, POST, OTIS, TAOS, GHAME, or equivalent).
• Exposure to threat modeling, EMS/plasma sheath effects, or seeker/RF performance modeling.
• Prior SETA or A&AS support to a government program office.
• M.S. in a relevant engineering discipline.

• Up to 25% CONUS, primarily to test ranges and sponsor sites.
