Electronics Hardware Design 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

• Develop schematics and multi-layer PCB layouts using Altium Designer.
• Perform component selection, circuit simulation, and design verification.
• Design power distribution, signal conditioning, and sensor interface circuits.
• Analyze signal integrity, power integrity, and EMC/EMI performance.
• Support board bring-up¹, debugging, validation, and root cause analysis.
• Collaborate closely with FPGA, embedded software, and mechanical engineering teams.
• Prepare design documentation, test procedures, and manufacturing documentation.
• Participate in design reviews and ensure compliance with  MIL-STD-461, MIL-STD-810 , and other applicable industry standards.
• Support prototype builds, qualification testing, and production transfer activities.

Who You Are

• Approximately 5+ years of professional experience in digital, mixed-signal, and analog hardware design for aerospace, defence, or other highly regulated industries.
• Experienced hardware design engineer with a track record of delivering deployed PCB-based electronics in aerospace, defense, or other highly regulated sectors.
• Skilled across digital, mixed-signal, and analog circuit design, with hands-on Altium Designer experience from schematic capture through multi-layer layout.
• Strong grasp of signal integrity, power integrity, and EMC/EMI principles, able to resolve competing physical constraints (space, thermal, cost, manufacturability).
• Comfortable owning designs end-to-end: simulation, verification, prototype bring-up, debugging, and root cause analysis.
• Collaborative across disciplines - works closely with FPGA, embedded software, and mechanical engineering teams.
• Rigorous and detail-oriented, with an instinct for reliability and compliance in mission-critical systems.
• Motivated by hands-on delivery of flight- or mission-critical hardware over theoretical work.

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.
