What you will do

• Design high-performance 6-DOF flight and physics simulations.
• Build simulation components that reproduce real-world dynamics and sensor behavior.
• Integrate guidance, navigation, and control logic into full-stack simulations.
• Develop Monte Carlo, hardware-in-the-loop, and closed-loop test infrastructure.
• Collaborate with flight software, autonomy, and hardware teams to match simulation fidelity to real-world constraints.
• Create tooling for scenario authoring, data visualization, performance analysis, and deterministic simulation pipelines.

Requirements

• Bachelor's degree in Computer Science or a related technical field.
• 7+ years of experience building simulations or numerical modeling frameworks.
• Proficiency in Rust and Python for performance-critical, test-driven development.
• Understanding of rigid body dynamics, kinematics, numerical integration, and physics.
• Experience building tools for flight dynamics, aerospace simulation, or autonomous systems.
• Must meet ITAR eligibility requirements, including U.S. citizenship or nationality, lawful permanent residence, refugee or asylee status, or eligibility to obtain required U.S. Department of State authorizations.

Nice to have

• Experience with Monte Carlo testing, sensor emulation, and closed-loop control validation.
