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

Design and analyze satellite antenna systems, including direct radiating array (DRA) antennas, reflector antennas and array fed reflector antennas.
Support all aspects of the development chain: requirements, architecture, design, manufacturing, integration, test, operations
Work with various teams (e.g., mechanical, electrical, software, thermal).
Support design reviews to ensure requirements and interface compliance
Work closely with external providers of antenna systems to write specifications, review designs, identify, and resolve issues and develop integration and test approaches
