Senior Modeling & Simulation Engineer

About the Company

Singularity Defense Corp. is a stealth-mode Aerospace & Defense startup headquartered in Gardena, CA. Our founding team hails from SpaceX, Anduril, and Lockheed Martin, and we are backed by Joint Staff-level military leadership and several Silicon Valley firms.

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

Requirements

• 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
• Understanding of rigid body dynamics, kinematics, numerical integration, and physics
• Experience building tools for flight dynamics, aerospace simulation, or autonomous systems
• Proficiency with compiled and scripted languages
• Must be a U.S. citizen, permanent resident, refugee, or asylee to comply with ITAR

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)
