STARK

ABOUT US STARK is a new kind of defence technology company revolutionising the way autonomous systems are deployed across multiple domains. We design, develop, and manufacture high-performance unmanned systems that are software-defined, mass-scalable, and cost-effective — providing operators with a decisive edge in contested environments. We are focused on delivering deployable, high-performance systems — not future promises. In a time of rising threats, STARK is bolstering the technological edge of NATO Allies and their Partners to deter aggression and defend Europe, today. YOUR MISSION STARK is building the next generation of counter-UAS capability, and we need an Electrical Engineer who wants to be at the sharp end of that problem. You'll sit within our C-UAS team in Swindon, owning the electrical design and integration of systems that need to work — reliably, in the field, under pressure. This isn't a maintenance role; you'll be shaping hardware that goes into operational environments. RESPONSIBILITIES * Design, develop, and validate electrical systems and subsystems in support of STARK's C-UAS product line. * Own schematic capture, PCB layout review, and electrical architecture documentation from concept through to production release. * Support hardware integration and bring-up, troubleshooting electrical issues across RF, power, and digital domains, including the integration of autonomy companion computers (SBCs), flight controllers, radio links, and high-power electric propulsion systems (EDFs/BLDC motors). * Collaborate closely with mechanical, software, and systems engineers to resolve cross-discipline design conflicts early. * Define and execute electrical test plans, including EMC/EMI considerations relevant to field-deployed defence systems. * Contribute to design reviews (PDR, CDR) and produce clear, accurate technical documentation. * Liaise with suppliers and contract manufacturers on component selection, lead times, and production quality. * Support field trials and customer demonstrations where electrical performance validation is required. QUALIFICATIONS * Degree in Electrical Engineering, Electronic Engineering, or a closely related discipline. * Proven experience (4+ years) in hardware/electrical engineering, ideally in a defence, aerospace, or high-reliability product environment. * Proficiency in schematic capture and PCB design tools (Altium preferred). * Solid understanding of power electronics, signal integrity, and mixed-signal design. * Familiarity with EMC standards and design-for-manufacture principles. NICE TO HAVE * Direct experience with UAS, C-UAS, EW, or RF-heavy systems. * Experience with the electrical integration of seeker payloads (e.g., EO/IR Gimbals) and fuzing mechanisms. * Exposure to STANAG or MIL-SPEC design requirements. * Experience supporting field trials or rapid prototyping in a defence startup or SME context. * Familiarity with DO-254 or similar airborne/defence hardware assurance frameworks. If you're interested in building the future of European Defence with us, and you see yourself reflected on the description above, please send us your CV in English. We´re looking forward to meeting you!
