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 and deliver mechanical engineering solutions across the full system lifecycle, from early concept through design, integration, test, and iteration.

Operate as a mechanical all‑rounder, bridging detailed component design with system‑level thinking to ensure coherent, flight‑ready hardware.

Lead mechanical design activities for structures, mechanisms, interfaces, and assemblies, balancing performance, manufacturability, and integration constraints.

Contribute to system architecture and requirements definition, ensuring mechanical design intent aligns with system‑level objectives and verification plans.

Develop and interpret analysis and simulation outputs (stress, thermal, structural behaviour), using results to drive sound engineering decisions.

Work closely with systems, GNC, avionics, propulsion, AIT, and manufacturing teams to ensure mechanical designs integrate cleanly into the wider vehicle.

Support integration, test, and build activities, diagnosing and resolving mechanical issues as they arise.

Identify system‑level risks and trade‑offs early, driving mitigations through design, analysis, or process changes.

Produce and maintain clear engineering documentation, including drawings, specifications, and design justifications.

Act as a technically credible problem‑solver in ambiguous environments, closing decisions and keeping programmes moving at pace.

Who you are

A senior Mechanical Engineer with strong breadth across both mechanical engineering and systems engineering.

Comfortable operating at multiple levels of abstraction from detailed component design to vehicle‑ or system‑level behaviour.

Experienced working on complex, integrated systems, ideally in aerospace, defence, or other high‑performance hardware environments.

Strong mechanical fundamentals covering structures, mechanisms, materials, interfaces, and tolerancing.

Systems‑minded, with experience interpreting and contributing to requirements, interfaces, and verification approaches.

Pragmatic and delivery‑focused, able to make sound engineering trade‑offs without over‑engineering.

Comfortable collaborating across disciplines and acting as a technical integrator, not just a specialist.

Hands‑on by instinct, willing to support build, integration, and test when needed.

Calm and effective in ambiguous, fast‑moving environments where priorities evolve.

Motivated by building real, high‑consequence hardware where mechanical and system correctness truly 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.

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.
