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.
As our Avionics EWIS Engineer, 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
- Establish and own the Electrical Wiring Interconnection System (EWIS) capability at Hypersonica, defining architectures, design rules, and integration practices from first principles.
- Design and route high reliability power and signal harnessing across flight and ground systems operating in extreme thermal, vibration, and EMI environments.
- Own harness architecture, connector strategy, shielding, grounding, and separation philosophy to ensure signal integrity and system robustness.
- Work hands-on with hardware, from early prototypes through flight articles, supporting build, integration, troubleshooting, and rework.
- Partner closely with avionics, propulsion, structures, and test teams to ensure electrical systems are flight-ready, manufacturable, and rapidly iterated.
- Define and evolve EWIS documentation, schematics, and configuration control in a fast moving development environment.
- Use test, integration, and flight feedback to continuously improve designs and eliminate single point failures.
Who you are
- An avionics or EWIS engineer with 3+ years’ experience designing cable harnesses in aerospace, space, or defence environments.
- Deeply experienced in high-power, low-power, and mixed-signal harness design, with an instinct for robustness and signal integrity.
- Comfortable owning detailed design decisions, from part selection and connector choice through to full BOM definition.
- Experienced producing manufacturing-ready documentation, not just concept designs.
- Someone who understands how electrical design choices show up in build, integration, and test, and designs accordingly.
- Able to balance engineering rigour with startup speed, making sound decisions with incomplete data.
- Motivated by building core capability from the ground up in a small team where your designs directly affect flight success.
- Energised by responsibility, ownership, and seeing your work fly, fail, and improve fast.
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.
