• Build high-fidelity 6
  
  DOF models of interceptor trajectories and target maneuvers.
• Model aerodynamic forces, flight regimes (subsonic → hypersonic), and uncertainties.
• Implement full state propagation with drag, atmospheric effects, gravity, and actuator limits.

• Implement orbital propagators, Lambert solvers, and multi-body dynamics.
• Model VLEO drag, solar flux, eclipse cycles, thermal conditions, and station‑keeping budgets.
• Quantify ΔV requirements for intercept geometries and constellation designs.

• Integrate GNC algorithms into simulation environments.
• Model perception pipelines: IR signatures, SNR, glint, thermal clutter, and atmospheric attenuation.
• Build closed‑loop simulations with perception → guidance → actuation → dynamics → intercept logic.

• Model particle trajectories, dispersal cones, cloud expansion, and lethality envelopes.
• Model impulse delivery mechanisms: blast, thrust, or hybrid dispersal events.
• Work with energetics engineers on momentary high‑G propagation and multi‑body interactions.

• Run large‑scale Monte Carlo simulations to evaluate hit probability, robustness, and margins.
• Develop parameter sweeps for timing, sensing errors, aerodynamic uncertainties, and ΔV constraints.
• Produce data‑driven design recommendations for system architecture decisions.

• Build clean, modular simulation tools in MATLAB/Python/C++ for internal engineering teams.
• Develop visualization tools (2D, 3D, orbital views) used for engineering and visual storytelling.
• Maintain code quality, performance, and model usability across the engineering org.

• B.S. or M.S. in Aerospace Engineering, Mechanical Engineering, Physics, Applied Mathematics, or similar.
• Strong experience with dynamic simulations (MATLAB, Simulink, Python, C++, Julia, or equivalent).
• Deep understanding of orbital mechanics, flight dynamics, or missile/rocket modeling.
• Experience with numerical methods, ODE/PDE solvers, filtering, integration stability, and optimization.
• Ability to validate simulated results against analytical solutions or experimental data.
• Strong intuition for physics and comfort working with incomplete or noisy data.
• U.S. citizenship required.

• Experience modeling hypersonic flow, ablation, or high‑enthalpy environments.
• Experience with high‑speed particle or fragment modeling.
• Experience connecting simulation to hardware‑in‑the‑loop systems.
• Familiarity with CFD tools (OpenFOAM, SU2, ANSYS Fluent).
• Experience with sensor modeling: IR/EO tracking, radar, radiometric models, or synthetic scene generation.
• Experience building custom visualization pipelines or simulation frameworks.
