Senior Power Systems 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 Own the electrical power system architecture for Hypersonica’s high-speed flight vehicles, ensuring generation, conversion, storage, distribution, protection, and monitoring functions operate as a coherent and resilient system. Define, manage, and maintain power system requirements, ensuring full traceability from mission and vehicle-level needs through subsystem design, verification, and validation. Develop power-system architectures and performance budgets covering voltage regulation, load management, efficiency, redundancy, thermal constraints, fault tolerance, and mission-critical availability. Lead the integration of power generation, battery systems, power electronics, energy storage, distribution networks, protection devices, and control systems across vehicle and payload architectures. Conduct electrical system analyses including load-flow, transient response, fault analysis, protection coordination, power quality, thermal performance, and reliability assessments. Define and support system-level modelling, simulation, laboratory testing, environmental qualification, and vehicle integration activities, using data-driven analysis to improve performance and mitigate risk. Produce and maintain critical engineering artefacts including specifications, electrical schematics, interface control documents (ICDs), analysis reports, verification plans, and design review material. Apply systems engineering and MBSE principles to ensure traceability between requirements, architectures, analyses, verification activities, and flight-test outcomes. Identify and mitigate system-level risks associated with power availability, thermal loading, EMC performance, reliability, safety, integration complexity, and operational resilience. Act as a technical authority across electrical power systems, collaborating closely with avionics, controls, software, thermal, mechanical, EMC, and systems engineering teams to deliver robust vehicle capability. Who you are An experienced Power Systems Engineer with 8+ years of experience delivering complex electrical power, energy storage, avionics, aerospace, defence, automotive, space, or other mission-critical systems. Strong background in electrical system architecture, requirements management, systems integration, verification, and validation across the full engineering lifecycle. Deep understanding of electrical power generation, power conversion, battery systems, energy storage, power distribution, protection systems, and power electronics. Experienced in electrical analysis including load-flow studies, transient response, fault analysis, protection coordination, power quality, thermal performance, and reliability assessments. Comfortable designing and integrating high-performance electrical power systems within highly constrained environments where weight, volume, efficiency, and thermal management are critical. Familiar with systems engineering and MBSE approaches, using structured methods to manage complexity, interfaces, traceability, and technical risk. Experienced supporting major design reviews, qualification campaigns, integration programmes, and the transition from concept through detailed design and verification. Technically credible across multiple engineering disciplines, capable of influencing decisions, challenging assumptions, and driving technical direction. Comfortable operating in ambitious, fast-paced environments where priorities evolve quickly and engineering decisions have significant programme impact. Motivated by solving difficult engineering problems and delivering technologies that strengthen European sovereign defence capability. 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 testing and operational activities 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. Security and Eligibility Requirement Due to the nature of the work, applicants must be an EU/Nato/German citizen and be eligible for German Security Clearance. At Hypersonica, every hire raises the bar. We are deliberately small, intensely capable, and deeply mission-driven. If this role feels like a strong fit, or if you believe you bring something exceptional that goes beyond the description, we encourage you to apply. Hypersonica is an equal-opportunity employer and assesses candidates solely on merit, capability, and potential. You can apply directly to this role or reach out to Nathan Sweeney, Head of Talent. We review every application and aim to respond to all candidates within two weeks, whether the answer is yes or no. Find more English Speaking Jobs in Germany on Arbeitnow
