Company

hirify.global is a stealth-mode aerospace and defense startup developing systems for high-demand military and autonomous applications.

What you will do

• Design high-performance six-degree-of-freedom flight and physics simulations.
• Build simulation components that reproduce real-world dynamics and sensor behavior.
• Integrate guidance, navigation, and control logic into end-to-end simulations.
• Develop Monte Carlo, Hardware-in-the-Loop, and closed-loop validation infrastructure.
• Collaborate with flight software, autonomy, and hardware teams to align simulation fidelity with real-world constraints.
• Create scenario-authoring, data-visualization, and performance-analysis tooling while owning pipeline performance and determinism.

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.
• ITAR eligibility or the ability to obtain the required authorizations from the U.S. Department of State.

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 or Bevy.
• Exposure to 3D rendering and contributions to aerospace open-source or simulation frameworks.
