Senior Antenna Engineer

Senior Antenna Engineer

iO Associates are partnering with an innovative and fast-growing organisation at the intersection of space and telecommunications, currently seeking a Senior Antenna Engineer to join their team in Toulouse.
This is a key opportunity to contribute to the development of next-generation satellite communication systems, supporting the delivery of high-performance, globally scalable connectivity solutions.

The Role
As a Senior Antenna Engineer, you will play a central role in the design and development of advanced ground terminal technology. You will work across the full product lifecycle, from early-stage simulation and prototyping through to integration, validation, and performance optimisation of antenna systems.

Key Responsibilities

• Lead the architecture and design of advanced antenna systems, including phased arrays and reflector-based solutions for millimetre-wave applications
• Define system-level RF architecture, balancing trade-offs between analog, digital, and hybrid beamforming approaches under SWaP and thermal constraints
• Conduct electromagnetic simulations (CST, HFSS) to optimise performance, including radiation patterns, efficiency, impedance matching, and scan capability
• Collaborate cross-functionally with RF, electronics, DSP, mechanical, and thermal teams to ensure fully integrated system performance
• Contribute to the development and validation of digital beamforming algorithms
• Oversee the full hardware lifecycle, including fabrication, testing, environmental qualification, and validation
• Support system-level integration activities and RF performance analysis
• Investigate field performance, troubleshoot anomalies and drive continuous improvement
• Provide mentorship and contribute to a culture of technical excellence and rigorous engineering standards

Experience Required

• MSc or PhD in Antenna Engineering, RF Engineering, or a related discipline
• 8+ years experience in antenna/RF design or research (including academic work)
• Strong grounding in electromagnetic theory and antenna design, particularly phased arrays
• Proven track record delivering antenna or phased-array systems
• Hands-on experience with CST, HFSS, or similar EM simulation tools
• Solid understanding of beamforming architectures (analog, digital, hybrid)
• Programming skills (Python, MATLAB, C#, or C++) are advantageous
• Experience with antenna measurement techniques and test environments
• Familiarity with prototyping and fabrication processes
• Fluent in French and English (written and spoken)
