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
• Develop test plans that ensure adequate testing of units and the complete system
• Execute in-lab testing and on-orbit performance validation, using advanced RF measurement tools (network analyzers, anchoic chambers, …).

Must have

• MSc or PhD degree in Electrical Engineering, Telecommunication Engineering, Aerospace Engineering, or related field
• 3+ years of experience in antennas for space
• Hands-on experience with telecom satellite antenna hardware
• Ability to be an individual contributor on technical definition, including:
• • Antenna analysis with relevant tools (Satsoft, GRASP, etc.)
  • Definition of antenna solutions, including antenna type (reflector, DRA, array fed reflector, etc.), appropriate geometry, performance
  • Interference analysis
  • Antenna performance analysis and simulation
  • Antenna sizing
  • Antenna performance budgets
  • Antenna hardware specification definition
• Demonstrated ability to work autonomously across teams and company to drive multi-disciplinary projects to completion
• Good communication skills
• Fluency in English

Nice to have

• A passion for technology and rapid execution of sophisticated space missions
• Intimate knowledge and connection with key suppliers of antenna payload hardware
• Knowledge of legacy customer architectures at deep technical level
• Experience in frequency coordination (ITU, FCC)
• Experience working on telecommunication satellite constellations
• Knowledge of software-defined radios (SDR) and digital signal processing (DSP)
