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
• 5+ 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

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)
