The team designs complex, real-time simulations that integrate real missile hardware — effectively allowing for controlled “indoor firings.”As an HWIL RF Engineer, you will play a key role in designing, developing, and maintaining both new and existing RF equipment. You’ll work closely with multidisciplinary teams to blend RF systems, electronics, and software into fully integrated, real-time simulations. This is a hands-on engineering role that requires adaptability and a high-level understanding of both abstract system behaviours and detailed hardware components.What We’re Looking For:Experience in Radio Frequency (RF) design and testingStrong system performance analysis skillsProficiency in interface debugging and system integrationUnderstanding of hardware/software design requirementsKnowledge of system design for real-time applicationsFamiliarity with Linux operating systemsA background in computer science (C++ is a plus)Experience with integrating microcontrollers into RF hardware (e.g., Raspberry Pi)
