Hardware Design Engineer

Help Build Europe’s Hypersonic Capability

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.

Hypersonica is an equal‑opportunity employer and assesses candidates solely on merit, capability, and potential.
