78 Avionic Hardware Desgin 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

• Design, prototype, and deliver electronic flight hardware that operates at the core of Hypersonica’s vehicles and launch systems. 

• Own the end‑to‑end avionics hardware design lifecycle, from concept and schematic capture through PCB layout, manufacturing, bring‑up, and test. 

• Develop and ship mission‑critical electronic units, including Flight Control Computers, Launcher Control Computers, Safe and Arming Devices, and related avionics. 

• Design digital, analogue, mixed‑signal, RF, and/or power electronics, applying strong engineering judgement to select the right architectures for safety‑ and performance‑critical systems. 

• Contribute to battery design and integration, where relevant, ensuring safe, reliable power delivery in demanding operational environments. 

• Produce manufacturing‑ready PCB designs, working closely with suppliers to prototype, assemble, and iterate hardware at pace. 

• Bring up and debug hardware hands‑on, diagnosing issues across schematics, layout, components, and interfaces. 

• Ensure avionics designs are robust, testable, and verifiable, supporting integration, HIL, AIT, and system‑level testing. 

• Design with regulatory, safety, and reliability constraints in mind, ensuring compliance with aerospace, defence, or space standards. 

• Collaborate closely with software, systems, GNC, and AIT engineers to ensure seamless integration of avionics into the wider vehicle architecture. 

• Feed lessons learned from test and integration back into design updates, continuously improving flight hardware maturity. 

Who you are

• An experienced Avionics or Electronics Hardware Design Engineer with a strong record of delivering real, deployed hardware. 

• Comfortable designing in at least two of the following domains: digital, analogue, mixed‑signal, RF, power electronics — or with strong experience in battery design and integration. 

• Hands‑on experience with PCB design, manufacturing, assembly, and prototyping, including supplier interaction and build support. 

• Accustomed to designing electronics for highly regulated environments, such as aerospace, space, aviation, or defence. 

• Detail‑oriented and rigorous, with a strong instinct for reliability, safety, and failure containment. 

• Comfortable working across disciplines, particularly with embedded software, systems engineering, and integration teams. 

• Able to debug complex hardware issues methodically under time pressure. 

• Pragmatic and delivery‑focused, able to balance technical elegance with schedule and manufacturability. 

• Motivated by shipping flight‑worthy electronics where correctness, robustness, and performance genuinely matter. 

• Driven to contribute to sovereign, high‑consequence aerospace capability, not theoretical or consumer‑grade hardware. 

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.
