Job summary

Quantum Space in Rockville, MD seeks a Spacecraft Thermal Engineer to lead the development, validation, and implementation of thermal control solutions for our high-mobility spacecraft platforms. You will work closely with a fast-moving team to shape in-space systems and ensure thermal performance from design through flight readiness.

You will model, test, and correlate thermal performance, participate in TVAC testing, and help drive tools and standards across the thermal ecosystem.

Qualifications

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or related field.
• 2+ years of relevant thermal engineering experience (spacecraft strongly preferred).
• Advanced proficiency in Thermal Desktop, SINDA/FLUINT, or equivalent thermal analysis tools.
• Experience with spacecraft flight hardware, integration, and thermal vacuum testing.
• Familiarity with NASA, commercial, and industry standards for spacecraft design.
• Demonstrated experience correlating thermal models with test data.

Responsibilities

• Develop high-fidelity spacecraft component thermal models for prediction of on-orbit performance.
• Review, refine, and correlate as-built thermal models and vendor-supplied thermal documentation.
• Collaborate with mechanical, electrical, and systems engineering teams to meet thermal requirements.
• Support thermal vacuum (TVAC) test planning, execution, correlation, and troubleshooting.
• Develop tools, workflows, and standards within the thermal ecosystem to improve efficiency.
• Generate simplified models, environments, and interface documentation for suppliers and customers.
• Review and approve component and assembly designs for thermal flight readiness.
• Produce engineering content and analyses for design reviews, test readiness reviews, and verification reports.
• Support integration, test, and launch-site operations for spacecraft thermal performance.
