Senior Power Electronics Engineer

Help Build Europe's Hypersonic Capability At Hypersonica , we’re redefining what’s possible in European defence technology. We exist to deliver speed, resilience, and technological independence at a pace that sets a new standard. We are a small, elite team working on problems that matter, and solving them fast. By joining Hypersonica , you’re not stepping into a predefined role. You’re joining a talent dense environment where every individual shapes the direction of the company. Our philosophy is to hire a small number of exceptional people with broad, deep technical capability, strong judgement, and the ability to operate autonomously. We hire for talent, not rigid boxes. This role represents a business need, but the way it evolves will be shaped by the individual. If you’ve achieved what others said was impossible, or you bring a unique combination of skills that doesn’t fit a traditional mould, we want to hear from you. The work you do here directly contributes to Europe’s technological independence. What you'll do • Design high-power electronic systems for demanding industrial, aerospace, or defense applications. • Develop schematics and PCB layouts for power electronics using Altium Designer. • Develop power distribution, protection, and switching circuits operating at high voltage and current levels. • Design DC/DC converters, power conditioning, and battery interface circuits. • Perform thermal analysis and optimize designs for efficiency and reliability. • Select power semiconductors, magnetic components, and protection devices. • Conduct circuit simulation and validate power electronics performance. • Support prototype testing, fault analysis, and hardware debugging. • Ensure compliance with (std), (std), (std), EMC, and reliability requirements. • Collaborate with mechanical and system engineers on integration and packaging. • Prepare technical documentation, test reports, and manufacturing support documentation. Who You Are • 8+ years of professional experience in power electronics design for industrial, aerospace, or defense applications. • Skilled in schematic capture and PCB layout for high-power electronics using Altium Designer. • Experienced designing DC/DC converters, power conditioning, battery interface, and high-voltage/high-current protection and switching circuits. • Proficient in thermal analysis, component selection (power semiconductors, magnetics, protection devices), and reliability-driven design optimization. • Comfortable validating designs through simulation, prototype testing, fault analysis, and hardware debugging. • Familiar with the compliance landscape for defense/aerospace power systems (EMC, reliability, and applicable safety standards). • Collaborative, working closely with mechanical and systems engineering teams on integration and packaging. What We Offer • A mission driven environment with the opportunity to work on one of Europe’s most consequential defence challenges, with direct impact on sovereign capability and security. • Daily collaboration with top experts across engineering, operations, and defence , with real opportunity to learn from the best, contribute, and grow. • High ownership and autonomy; no time tracking, no micromanagement , just clear objectives and accountability for outcomes. • A fast paced environment where good ideas are implemented quickly, and feedback from test and flight drives real decisions. • A culture that values clarity, integrity, and excellence, and supports people who take initiative and push boundaries responsibly. • Competitive compensation and real share options aligned to responsibility and impact, not tenure or hierarchy. At Hypersonica, every hire raises the bar. We are deliberately small, intensely capable, and deep
