Company

hirify.global is a stealth-mode aerospace and defense startup developing software and systems for high-performance autonomous platforms.

What you will do

• 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 logic into full-stack simulations.
• Develop Monte Carlo, Hardware-in-the-Loop, and closed-loop test infrastructure.
• Create tools for scenario authoring, data visualization, and performance analysis.
• Own simulation pipeline performance and determinism while collaborating with flight software, autonomy, and hardware teams.

Requirements

• Bachelor’s degree in Computer Science or a related technical field.
• 5+ years of experience building simulations or numerical modeling frameworks.
• Proficiency 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.
• Must meet U.S. ITAR eligibility requirements as a U.S. citizen or national, lawful permanent resident, refugee, asylee, or an individual eligible to obtain the required U.S. authorizations.

Nice to have

• 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 such as missiles, drones, satellites, or vehicles.
• Familiarity with Rust game engines or physics libraries such as Rapier and Bevy.
• Experience with 3D rendering or contributions to aerospace open-source and simulation frameworks.

Culture & Benefits

• Work with a founding team from SpaceX, Anduril, and Lockheed Martin.
• Collaborate across flight software, autonomy, and hardware disciplines.
• Develop simulation infrastructure for systems that require reliable first-time performance.
