Design Engineer - Electronics

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 a Design Engineer focused on Electronics, you will create innovative concepts for the mechanical integration of electronic boards, connectors, and harnesses, ensuring their proper form, fit, and function. Your expertise will be vital in realising robust, scalable, and cost-effective solutions that enhance the performance of Helsing's systems, directly supporting our mission to provide advanced defence capabilities. The day-to-day Design and develop electronic circuits and PCBs — from requirements capture through schematic design to layout — covering power electronics, digital electronics, and mixed-signal architectures Collaborate proactively with mechanical, software, and systems engineers to ensure seamless integration of electronic assemblies into the airframe and overall system architecture Drive requirements-to-design traceability, actively supporting requirements flow-down and contributing to aircraft-level (A/C) requirements and flight support documentation Design and integrate cable harnesses and connectors, including selection, routing, and integration into complex electromechanical assemblies Develop and execute unit-level tests and support system-level integration and flight testing, troubleshooting issues pragmatically across hardware/software boundaries Produce complete design documentation including schematics, PCB layouts, BOMs, and integration drawings using tools such as Altium Designer or KiCad Perform circuit simulation and analysis using tools such as LTSpice to validate design decisions early in the development cycle Contribute to reliability and safety analyses, including FMEA and reliability prediction, to ensure designs meet required standards Design and integrate communication interfaces, including protocols such as CAN Bus, Ethernet, RS422/485 and similar interfaces, ensuring robust and reliable data and power distribution across the platform Work with RF and radio systems, including datalinks, GNSS, SATCOM, and other radio-frequency technologies relevant to UAV platforms, ensuring reliable connectivity and positioning across all operating conditions Support production and test teams throughout the manufacturing, bring-up, and verification phases, providing hands-on engineering support on the shop floor when needed Stay curious and keep learning — our domain evolves rapidly, and we value engineers who actively seek out new technologies, methods, and best practices You should apply if you Have professional working experience in electronic circuit design, PCB design and layout, covering power electronics, digital electronics, and mixed-signal systems — ideally within aerospace, UAV, or similarly demanding domains Are proficient in PCB design tools such as Altium Designer or KiCad, and comfortable using circuit simulation tools such as LTSpice for design validation and analysis Have an understanding of RF and radio systems used in UAV or aerospace applications — including datalinks, GNSS, SATCOM, and related antenna and signal integrity considerations Have hands-on experience with onboard communication protocols such as CAN Bus, Ethernet, and similar digital interfaces, and understand
