Weapon Systems Engineer - #2747189

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

• Lead Weapon System Integration: Own the full integration of our effects solutions into the overall system.
• Manage Interfaces: Take ownership of the interfaces that define the critical connections between the payload and the rest of the system.
• Execute System Trade-Offs: Lead cross-functional analysis to balance effectiveness requirements against system constraints, and present outcomes to your team.
• Develop Test & Evaluation Plans: Design and lead the validation and verification strategy for our products, including interaction with external stakeholders.
• Drive Design Decisions: Translate complex data into clear engineering requirements, optimizing the final seconds of flight.
• Support Technical Reviews: Support technical reviews (PDR/CDR/TRR) and flight readiness reviews and ensure compliance with applicable defence and quality standards (e.g. Mil-std, customer specifications).
  
  

Who You Are

• You have 3+ years of experience in systems engineering, with a focus on weapon integration, aerospace, or complex kinetic systems.
• You have a proven track record of managing complex hardware/software interfaces and maintaining the overview to keep a multi-disciplinary team aligned.
• You are comfortable taking analytical data and using it to distil key parameters that influence the entire system's effectiveness.
• You thrive in high-pace, startup-like environments. You can build processes from scratch and navigate ambiguity without losing momentum.
• Degree in Aerospace, Mechanical, or Electrical Engineering, or equivalent practical experience.
  
  

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. 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.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
