RF & EMC Engineer

Who we are Helsing is a defence AI company. Our mission is to protect our democracies. We aim to achieve technological leadership, so that open societies can continue to make sovereign decisions and control their ethical standards. As democracies, we believe we have a special responsibility to be thoughtful about the development and deployment of powerful technologies like AI. We take this responsibility seriously. We are an ambitious and committed team of engineers, AI specialists and customer-facing programme managers. We are looking for mission-driven people to join our European teams – and apply their skills to solve the most complex and impactful problems. We embrace an open and transparent culture that welcomes healthy debates on the use of technology in defence, its benefits, and its ethical implications. The role As RF & EMC Engineer, you will own the electromagnetic architecture of Helsing's drone platforms, from board level through to platform certification and field operations. Working across electronics, mechanical and systems engineering teams, you will define antenna placement, govern RF interfaces across onboard radio systems and embed EMC requirements into designs before they become costly fixes. Your analyses, test campaigns and technical guidance directly determine the electromagnetic cleanliness, compliance and operational robustness of Helsing's platforms in complex, congested radio environments. The day-to-day Define and own the platform-level RF and EMC concept from early design through to certification, including antenna placement and selection, frequency management, co-site interference analysis and requirements traceability from system level down to LRU and component level Perform platform-level RF and EMC analyses covering link budgets, antenna pattern assessment, cable shielding effectiveness and conducted and radiated interference predictions, translating outputs into clear design requirements for electronics, mechanical and systems engineers Work closely with radio engineers to define clean RF interfaces across C2 links, datalinks, GNSS and SATCOM, ensuring robust frequency co-existence across the full platform radio architecture Guide and support EMC test campaigns at board, LRU, system and platform level, providing test strategy, setup guidance and real-time engineering judgement, and driving root cause analysis and corrective actions for any non-conformances identified Write and maintain EMC control plans, test plans, RF interface documents and analysis reports to the standard of clarity and rigour required for defence and aerospace programme compliance You should apply if you Have owned RF and EMC engineering within aerospace, UAV or defence programmes, including hands-on antenna selection and placement on complex platforms with an understanding of radiation patterns, ground plane effects, co-site interference and mechanical integration constraints Have performed platform-level EMC analysis covering conducted and radiated emissions, susceptibility, shielding effectiveness and bonding and grounding, and have supported or led test campaigns against standards such as MIL-STD-461 or DO-160 Can produce link budgets and RF system analyses and translate them into antenna and radio system requirements, with working knowledge of onboard radio systems including C2 links, datalinks, GNSS and SATCOM and their co-existence challenges in UAV or aerospace applications Can define and manage RF and EMC requirements with full traceability across the system hierarchy, working cross-functionally with electronics designers, mechanical engineers and radio specialists to embed requirements early in the design cycle Act decisively with minimal guidance, own outcomes end-to-end and initiate solutions without waiting for direction Note: We operate in an industry where women, as well as other minority groups, are systematically under-represented. We encourage you to apply even if you don’t meet all the listed qualificati
