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, mech
