2–4 years of related experience in RF or space system engineering.
Knowledge of payload architectures, RF design, repeater subsystems, and antenna systems.
Experience with link budgets, waveform design, modulation/coding (ModCod), and telecom protocols (5G, DVB, etc.).
Familiar with RF performance measurement, integration testing, and quality control processes.
Experience with UHF/L-Band technologies and IoT architecture concepts is a plus.
Proficiency with engineering tools such as STK, Satsoft, and MATLAB.
Programming experience (Java, C, Simulink) is a valuable asset.
Excellent written and spoken English; Italian nationality preferred.
Willingness to work part-time at customer premises (Vigna di Valle) is a strong advantage.
