Thermal Engineer

About Aerospacelab

Our mission is supported by an ambitious vertically integrated approach: design & manufacture of small satellites combined with development of earth observation services.

Since its creation in 2018, the company has already grown substantially. Our team gathers more than 25 engineering expertise, from hardware design to software development & data science.

In 2025, Aerospacelab counts offices in Louvain-la-Neuve (Belgium), Toulouse (France), Lausanne (Switzerland) and US West Coast with more than 300 full-time employees, with the ambition to position itself as the European leader in small satellites.

Role overview

Asa Thermal Engineer at Aerospacelab, you will play a critical role in designingand implementing thermal control solutions for satellites across variousmissions. Utilizing your expertise in thermal engineering, you will be key inensuring that all components remain within their operational temperature rangesthroughout their missions. Collaborating with multidisciplinary teams, you willguide the thermal design from concept through launch, focusing on thermalstability and performance.
