Company

hirify.global develops reusable, safe, and low-cost space vehicles and systems, including the New Glenn heavy-lift orbital launch vehicle.

What you will do

• Design, implement, analyze, and revise mathematical models of New Glenn, its orbital launch site, and associated subsystems using first principles and test data.
• Develop simulation architectures and models for real-time software-in-the-loop and hardware-in-the-loop testing.
• Maintain model documentation and databooks, and assist engineers across the company with simulation product development.
• Support systems analysis and system-level architectural decisions across guidance, control, aerodynamics, propulsion, mechanical, fluid, electrical, and thermal domains.
• Develop verification and validation procedures, support component-level and integrated on-site testing, and perform post-test analysis.
• Prepare and operate the simulator during launch crew training sessions.

Requirements

• Bachelor’s degree in aerospace, computer science, electrical or mechanical engineering, physics, or a related field.
• 7+ years of relevant experience.
• Knowledge of dynamic modeling, including multi-body dynamics, gas dynamics, fluid mechanics, and thermodynamics.
