Senior Modeling & Simulation Engineer

Job Overview As a GNC Engineer focused on simulations, you will lead the development of high‑fidelity physics‑based simulations for end‑to‑end missile flight and guidance validation. These simulations serve as a digital proving ground for our flight software, autonomy stack, and control systems—enabling us to iterate rapidly and validate in silico what would otherwise require expensive, slow, or impossible real‑world testing. You’ll own simulation architecture, real‑time physics integration, and testbed development. If you’re comfortable writing performant simulation code in Rust and Python, and you’re looking to do impactful work on a system that must work the first time, this is your chance. Key Responsibilities Design high‑performance 6‑DOF flight and physics simulations Build simulation components that replicate real‑world dynamics and sensor behavior Integrate guidance, navigation, and control (GNC) logic into full‑stack simulations Develop Monte Carlo, Hardware‑in‑the‑Loop (HITL), and closed‑loop test infrastructure Collaborate closely with flight software, autonomy, and hardware teams to ensure simulation fidelity matches real‑world constraints. Create tooling to support scenario authoring, data visualization, and performance analysis. Own simulation pipeline performance and determinism across a wide range of conditions Basic Qualifications Bachelor’s degree in Computer Science or a related technical field 7+ years of experience building simulations or numerical modeling frameworks Proficient in Rust and Python for performance‑critical and test‑driven development Understanding of rigid body dynamics, kinematics, numerical integration, and physics Experience building tools for flight dynamics, aerospace simulation, or autonomous systems Proficiency with compiled (e.g., C++, Rust) and scripted (e.g., Python) languages Preferred Qualifications Experience with Monte Carlo testing, sensor emulation, and closed‑loop control validation Familiarity with real‑time systems, latency‑sensitive architectures, or distributed simulation Experience deploying or validating autonomous systems (missiles, drones, satellites, or vehicles) Familiarity with Rust game engines or physics libraries (e.g., Rapier, Bevy) Exposure to 3D rendering for simulation visualization (e.g., WebGL, OpenGL, Three.js) Contributions to aerospace open source or simulation frameworks (e.g., JSBSim, Gazebo) ITAR Requirements To conform to U.S. Government export regulations, applicant must: be a U.S. citizen or national, a U.S. lawful permanent resident (green card holder), a refugee under 8 U.S.C. 1157, or an asylee under 8 U.S.C. 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
