Cyber Security Architect – Space & Ground (All Genders)

As a Cyber Security Architect – Space & Ground, you play a key role in shaping the security architecture of next-generation satellite missions. You define, evaluate, and ensure compliance with high-assurance cybersecurity requirements across both space and ground systems.
This role requires deep expertise in security engineering, applied cryptography, and satellite communication or navigation systems. You work closely with internal teams, external partners, subcontractors, and international authorities.

• Define guidelines and processes for managing the development lifecycle of security-relevant requirements.
• Plan, lead, and execute security evaluations and certifications of products according to Common Criteria (CC).
• Engineer and design safety- and security-critical requirements for both ground and space segments of satellite missions.
• Create and maintain technical documentation, including device specifications, Interface Requirement Documents (IRDs), and Interface Control Documents (ICDs).
• Manage and control subcontractors, including quotation assessment, milestone reviews, delivery evaluations, and preparation of change requests.
• Drive communication with internal and external project partners; discuss safety and security aspects with authorities, certification bodies, and institutions.

Required Qualifications:

• Completed university degree or PhD in Electrical Engineering, Communications Engineering, Mathematics, Physics, Computer Science, or a related field.
• Strong background in information systems and systems engineering.
• Proven experience in Requirements Engineering and the V-Model development process.
• Expertise in satellite communications, satellite navigation programmes, or comparable aerospace systems.
• Professional experience in applied cryptography, such as cryptographic device development, key device operation, or secure system design.
• Familiarity with cryptographic algorithms and protocols (e.g., AES, Poly1305, authentication methods).
• Knowledge of IT security for cryptographic devices, including red-black separation, tamper protection concepts, and secure operational environments.
• Experience supporting evaluations based on Common Criteria, ISO/IEC 27000 series, and/or NATO security regulations.

Nice to have:

• Experience with security risk analysis, such as the EBIOS methodology.
• Understanding of satellite system architecture, ground-to-space communication, and on-board data handling.
• Familiarity with UML, SysML, and programming languages such as C++ or Python.
• Knowledge of ground segment engineering and spacecraft operational concepts.
