How to Apply for Spacecraft Thermal Engineer

at Muon Space

🏢 About Muon Space

Muon Space is revolutionizing climate action by developing cutting-edge Earth-sensing satellite technology specifically designed to address environmental challenges. Unlike traditional aerospace companies, Muon focuses exclusively on climate solutions, offering engineers the unique opportunity to directly contribute to meaningful environmental impact through space technology. Their mission-driven approach makes them particularly appealing to engineers who want their technical work to serve a larger purpose.

About This Role

As a Spacecraft Thermal Engineer at Muon Space, you'll lead thermal design efforts across the entire spacecraft mission lifecycle for climate-focused satellites. This role involves designing thermal management subsystems, building simulations for on-orbit performance, and implementing thermal components into Muon's integrated systems modeling tools. Your work will directly ensure the reliability of Earth-sensing instruments that monitor climate change, making this position critical to Muon's mission of providing actionable climate data.

💡 A Day in the Life

A typical day involves collaborating with other subsystem leads to integrate thermal requirements into spacecraft designs, running Thermal Desktop simulations to predict on-orbit performance of climate-sensing instruments, and developing thermal verification plans for upcoming TVAC tests. You'll spend time implementing thermal components into Muon's integrated modeling tools and working with both internal teams and external stakeholders to validate hardware systems at various integration levels.
