Job summary

Hypersonica, a UK defence tech innovator, seeks an experienced Systems Engineer to own the system architecture for Europe’s high-speed flight vehicles. You will shape mission requirements, vehicle dynamics, avionics, and GNC into a coherent, verifiable whole.

You will lead architecture design through early concept, PDR, and beyond, build an authoritative requirements model, and define the end-to-end V-model with validation and verification strategies.

Qualifications

• Experience in system architecture, requirements decomposition, and delivery in safety-critical environments.
• Fluency in MBSE to drive engineering decisions.
• Strong grounding in closed-loop control theory for high-speed flight or defence systems.

Responsibilities

• Own the system architecture and model for Hypersonica's high-speed flight vehicles.
• Lead aerospace systems architecture design across disciplines from concept to PDR.
• Build and maintain the authoritative system requirements model with testable requirements.
• Define and own the end-to-end system V-model with validation and verification strategy.
• Apply MBSE as a practical engineering tool ensuring traceability between requirements, models, analyses, and tests.
• Develop and deliver a 6-DoF GNC model to PDR standard in collaboration with flight physics and avionics engineers.
• Apply closed-loop control theory to ensure controllability, stability, and performance at the system level.
• Integrate vehicle dynamics, control laws, sensors, and actuators into a coherent closed-loop system representation.
• Identify system-level risks early and drive mitigations decisively.
• Act as a technical authority across disciplines to maintain architectural coherence as designs evolve.

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.

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.
• Security and Elgibility Requirement Due to the nature of the work with the U
