Modeling and Simulation Engineer (Aerospace)

Location: Houston, United States; generally office-based

Company

hirify.global develops commercial human spaceflight services, orbital infrastructure, advanced spacesuits, and technology-driven solutions for space exploration.

What you will do

• Develop high-fidelity fluid, thermal, and electrical simulation models for EVA spacesuit analysis and verification.
• Use NASA Trick, GUNNS, nodal analysis methods, and existing simulation frameworks.
• Collaborate with spacesuit subsystem teams to represent life-support component designs and operational details accurately.
• Debug, test, verify, validate, document, and integrate model packages into the broader simulation framework.
• Assess simulation credibility through uncertainty characterization, robustness analysis, and sensitivity analysis.
• Evaluate spacesuit performance, conduct trade studies, verify system requirements, and communicate progress and risks to stakeholders.

Requirements

• Bachelor’s degree in engineering or a related technical field for Levels II–III; a master’s degree or Ph.D. is preferred for Levels IV–V.
• Experience designing or modeling fluid, thermal, or electrical systems and performing simulation credibility assessments.
