Systems Engineer (Security) - Space

Helsing is a defence AI company. Our mission is to protect our democracies. We aim to achieve technological leadership, so that open societies can continue to make sovereign decisions and control their ethical standards.

As democracies, we believe we have a special responsibility to be thoughtful about the development and deployment of powerful technologies like AI. We take this responsibility seriously.

We are an ambitious and committed team of engineers, AI specialists and customer‑facing programme managers. We are looking for mission‑driven people to join our European teams – and apply their skills to solve the most complex and impactful problems. We embrace an open and transparent culture that welcomes healthy debates on the use of technology in defence, its benefits, and its ethical implications.

Role

As a Security Systems Engineer, you will lead the end‑to‑end security architecture for our upcoming satellite constellations. You will take ownership of the mission's security posture, bridging the gap between space systems, ground segments, external partners, and our customers. Your primary responsibility is to ensure that our constellation is secure by design from day one, designing the overarching security concept of operations and translating complex security requirements into actionable, high‑impact engineering outcomes.

Day‑to‑day

• Overall Security Concept: Lead the design, development, and maintenance of the overarching security architecture and concept of operations (CONOPS) for the constellation programme.
• Space Segment Security: Drive the integration and implementation of specialized satellite security units (e.g., cryptographic and COMSEC hardware) into the overall satellite bus and payload design.
• Ground Segment Security: Oversee the implementation and integration of ground security units within the overall Ground Control Segment (GCS) and Mission Control Segment (MCS), ensuring secure command, control, and data downlinks.
• Primary Security Liaison: Serve as the single point of contact for both our government customer and our industrial partners regarding all security‑related engineering, compliance, and operational matters.

You should apply if you

• Have successfully delivered complex systems engineering or security engineering solutions within aerospace, defence, or telecommunications projects.
• Possess deep expertise operating within highly classified environments and implementing strict military and government security frameworks.
• Hands‑on experience integrating hardware and software security units, cryptographic modules, and secure communications protocols into complex technical systems.
• Can clearly and concisely translate complex security requirements to non‑security engineers, customers, and executive stakeholders.
• Hold an advanced degree in Cybersecurity, Electrical Engineering, Computer Science, Aerospace Engineering, Systems Engineering, or a related STEM discipline.
• Collaborate effectively with multidisciplinary teams, including payload engineers, ground software developers, and mission operators, to deliver secure cross‑functional solutions.

Nice to have

• Experience working specifically with space or ground systems.

What we offer

• Competitive salary and stock options (ESOP).
• Relocation support: up to €2,500 and 4 weeks temporary accommodation.
