Telecommunication Systems Engineer

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.

Duties

• Design and analyze satellite communication systems, including size and number of beams, bandwidth, coverage, … to meet system requirements (capacity, throughput, …).
• Develop RF link budgets and conduct performance assessments using (custom) simulation tools.
• Design modulation, coding, and multiplexing techniques for reliable satellite links.
• Work with the designers and the customer on high-level architecture.
• Support all aspects of the development chain: requirements, architecture, design, manufacturing, integration, test, operations
• Work on RF / telecommunication spacecraft architecture with various teams (e.g. RF, electrical, software, FPGA, network).
• Support design reviews to ensure requirements and interface compliance
• Work closely with external providers of telecommunication systems to review designs, identify, and resolve issues and develop integration and test approaches
