Avionic Hardware 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 Avionic Hardware Engineer, you will own the integration of avionic systems onto Helsing's drone platforms, working across architecture, component selection, hardware and software integration, flight testing and series production. Working across hardware and software boundaries with equal confidence, you will drive fault isolation, requirements traceability and production scalability. The day-to-day Contribute to avionic system architecture decisions and LRU selection from the start of the design cycle, providing integration and production feasibility input that directly shapes component choices, system topology and scalability from prototype to series production Integrate avionic LRUs onto the airframe, including mounting, harness routing, connector mating and configuration management, and collaborate with software engineers on hardware and software integration covering board bring-up, firmware flashing, interface verification and debug Perform system-level fault isolation across hardware, software and mechanical boundaries using schematics, ICDs, logic analysers and oscilloscopes, managing non-conformances and root cause analyses and driving corrective actions to verified closure Develop and execute integration and acceptance test procedures with full traceability to system and LRU-level requirements, supporting ground and flight test campaigns with hands-on troubleshooting in real time Own the serialisation and productionisation of avionic LRUs, developing production test procedures, acceptance criteria and workmanship standards that enable consistent, repeatable production at scale, and contribute to safety analyses including FMEA and hazard identification throughout integration and test You should apply if you Have integrated avionic or electronic hardware within UAV, aerospace or defence programmes, working across architecture input, LRU selection, harness integration and configuration management with a clear understanding of how requirements flow down through subsystems Have taken hardware from prototype to series production, owning serialisation, productionisation and the development of workmanship standards that enable scaling without quality loss Can work at the hardware and software interface, with hands-on experience in embedded systems debug, firmware bring-up, log analysis and familiarity with protocols such as CAN Bus, Ethernet, MIL-STD-1553 and ARINC 429 Have planned and executed integration, acceptance and flight test campaigns, performed circuit-level fault analysis using lab equipment, and managed NCs and RCAs through to verified closure in a regulated development environment 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 qualifications; ability and impact cannot be summarised in a few bullet points.
