Senior V&V Systems Engineer

Job description

**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 impact genuinely matter. ### Security and Elgibility Requirement Due to the nature of the work with the UK MOD, applicants must be a British Citizen (or Dual UK national with British citizenship) and eligible for UK Security Clearance (SC) and, where required, Developed Vetting (DV) ### 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.
