Communication System 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 and specify communication links between vehicle and ground segment, including RF link budgets, waveform selection, and data rate/latency requirements. 

• Define communication system requirements and interfaces with avionics, ground segment, and flight control teams. 

• Support integration, bench test, and field test of communication hardware and protocols. 

• Analyze link performance and troubleshoot anomalies during integration and test campaigns. 

• Evaluate and select RF components, antennas, and transceiver hardware in collaboration with suppliers. 

• Maintain technical documentation in line with requirements. 

Who You Are 

• Degree in Electrical Engineering, Telecommunications, or a related field. 

• Experience in RF/communications system design: link budgets, modulation/coding schemes, antenna systems. 

• Familiarity with data link protocols used in aerospace or defence applications. 

• Hands-on experience with RF test equipment (spectrum analyzers, signal generators, network analyzers). 

• Strong analytical and troubleshooting skills. 

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. 

Security and Eligibility Requirement 

Due to the nature of the work, applicants must be an EU/NATO/German citizen and eligible for Security Clearance. 

At Hypersonica, every hire raises the bar. We are deliberately small, intensely capable, and deeply mission-driven.

We review every application and aim to respond to all candidates within two weeks, whether the answer is yes or no.
