Digital Design Engineer (FPGA)

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 and implement FPGA architectures using VHDL or Verilog.
• Develop digital signal processing (DSP) algorithms for real-time applications.
• Implement high-speed communication interfaces (PCIe, Ethernet, Aurora, LVDS, etc.).
• Optimize FPGA resource utilization, timing closure, and power consumption.
• Develop simulation environments and verification testbenches.
• Integrate FPGA designs with embedded processors and hardware platforms.
• Debug FPGA designs using laboratory equipment and on-chip debugging tools.
• Collaborate with hardware and software engineers throughout system development.
• Prepare design documentation and maintain version-controlled FPGA projects.
• Contribute to system architecture decisions and provide technical leadership within the FPGA domain., * 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.

• 8+ years of professional experience in FPGA design and digital system development, with deep VHDL/Verilog expertise.
• Proven track record implementing DSP algorithms for real-time applications and high-speed interfaces (PCIe, Ethernet, Aurora, LVDS).
• Skilled in timing closure, resource optimization, and power-aware FPGA design.
• Experienced building simulation environments and verification testbenches; comfortable with on-chip debugging tools and lab-based validation.
• Able to integrate FPGA designs with embedded processors and hardware platforms.
• Provides technical leadership within the FPGA domain and contributes to system architecture decisions.
• Collaborative, working closely with hardware and software engineering teams across the full development lifecycle.
