Modeling & Simulation Engineer - Junior

About IWV 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. Position Summary Iron Will Ventures (IWV) seeks a Junior Modeling & Simulation Engineer to support hypersonic and strike weapon system development, test planning, and analysis at NSWC Crane. The successful candidate will work within a team to 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. Key Responsibilities Learn to develop, modify, and execute AFSIM scenarios and platform/sensor/weapon models to support mission-level trade studies, campaign analysis, and capability gap assessment. Develop proficiency in building and validating 3-DOF and 6-DOF flight dynamics models for hypersonic and tactical missile configurations; support aero database integration, GNC model insertion, and Monte Carlo dispersion analysis. Contribute to team generation of trajectory products supporting flight test planning: nominal and Monte Carlo 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. Required Qualifications Eligible for DoD Secret clearance. Bachelor's degree in Aerospace, Mechanical, or Electrical Engineering, Physics, or Applied Mathematics. Ability to learn AFSIM at proficient level — scenario construction, model development, and results analysis (not solely end-user operation). Ability to learn 6-DOF simulation experience for missiles, launch vehicles, or hypersonic vehicles. Ability to work on-site at NSWC Crane and travel as required. Desired Qualifications 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. 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. M.S. in a relevant engineering discipline. Travel Up to 25% CONUS, primarily to test ranges and sponsor sites. Iron Will Ventures Inc. is an equal opportunity employer.
