From all manner of backgrounds, our engineers, scientists, and ex-military personnel combine their experience to help our customers achieve true operational potential and help keep their people and platforms safe.\nAre you looking for a role that can design and build analogue RF circuits to integrate complex RF systems? Do you enjoy deploying and testing hardware models? This role will allow you to use your skills integrating and verifying novel conceptual, in-service, and legacy RF systems in a cutting-edge, first-of-its-kind synthetic range.\nWith the continual improvement in COTS RFSoC technologies and associated RF waveform performance, the proliferation through our synthetic range of these payloads will only increase. Combined with a drive for more synthetic trials to assure performance, train operators, and design tactics and procedures, this is an excellent growth area for your career.\nWorking full-time at our St Neots site, you will help deliver high-importance synthetic trials to a variety of government and industry partners, each with their own requirements to be verified. Your ability to ensure automated and repeatable solutions will greatly impact the success of these trials.\nThe invaluable experience you’ll bring, to help us achieve more.\nEssential:\nStrong knowledge of RF analogue designs and testing (e.g. trade-offs between bandwidth and signal purity). \nScaling and calibration activities to ensure synthetic environments are correctly represented to real-time HIL systems.\nExperience writing test automation scripts for real-time systems (MATLAB, Python, LabView etc.).\nAbility to solve problems in a methodical manner.\nSTEM degree.\nDesirable:\nExperience using test bench equipment (signal generators, spectrum analysers, oscilloscopes, network analysers, power meters) to assure repeatable integration activities.\nGeneration of test harnesses for hardware model interfaces (Analogue RF, Digital IQ, TCP/IP, UDP, JTAG, UART etc.)\nFamiliarity with synchronisation and timing architectures.\nNetwork debugging and fault-finding (package/port level).\nExperience implementing ICDs/APIs and reviewing documentation for customer System-Under-Test (SUT).\nExperience with PCB design and manufacture.\nSafety-conscious approach when working with RF equipment.\nKnowledge of EW systems.\nWellbeing is at the core to our culture, allowing employees to flourish and to achieve their full potential.
