Verification & Test 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 system architecture and system model for Hypersonica’s high‑speed flight vehicles, ensuring mission intent, vehicle dynamics, avionics, and GNC form a coherent, verifiable whole. • Lead aerospace systems architecture design , taking responsibility for how the vehicle is defined across disciplines from early concept through Preliminary Design Review (PDR) and beyond . • Build and maintain the authoritative system requirements model , decomposing mission‑level objectives into clear, testable system and sub‑system requirements. • Define and own the end‑to‑end system V‑model , including requirements validation, verification strategy, and clear readiness gates for Kick‑off and PDR. • Apply model‑based systems engineering (MBSE) as a practical engineering tool, not a documentation exercise, ensuring traceability between requirements, models, analyses, and tests. • Develop and deliver a 6‑DoF Guidance, Navigation, and Control (GNC) model to PDR standard, in close collaboration with flight physics and avionics engineers. • Apply closed‑loop control theory in the context of high‑speed flight and military guidance, ensuring controllability, stability, and performance are understood at the system level. • Integrate vehicle dynamics, control laws, sensors, and actuators into a coherent closed‑loop system representation. • Identify system‑level risks early particularly around requirements gaps, controllability, observability, and verification — and drive mitigations decisively. • Act as a technical authority across disciplines, keeping architectural decisions coherent as designs evolve at pace. Who you are • An experienced Systems Engineer with a strong track record in system architecture, requirements decomposition, and delivery in safety‑ or mission‑critical environments. • Deeply fluent in model‑based systems engineering , with practical experience owning requirements models and using MBSE to drive real engineering decisions. • Strong grounding in closed‑loop control theory , applied to high‑speed flight, guidance, and defence or military systems. • Comfortable developing and working with 6‑DoF flight and GNC models , and understanding their implications at vehicle level. • Experienced taking systems through early design gates (Kick‑off, PDR), not just theoretical or paper studies. • Someone who thinks in system behaviours , interfaces, and failure modes , not isolated components. • Confident operating in ambiguous, fast‑moving environments where decisions must be made with incomplete data. • Technically credible across disciplines, able to challenge assumptions and close decisions without consensus theatre. • Motivated by working on systems where performance, robustness, and national‑level im
