• Serve as the technical point of convergence for multi‑entity satellite missions involving separate upstream and downstream contractors.
• Define, maintain, and validate system‑level architecture, interfaces, and end-to-end performance requirements across mission domains (satellite, ground segment, operations, and data services).
• Oversee technical execution and system integration across participating contractors, ensuring schedule and performance alignment without directly managing their teams.
• Review and evaluate technical deliverables from satellite manufacturers, ground segment providers, and data service integrators.
• Ensure interoperability and compliance with program objectives, regulatory constraints (e.g., ECSS, ITU, national policies), and mission requirements.
• Lead and participate in cross‑domain technical reviews (e.g., SRR, PDR, CDR, ORR), providing system‑level validation and integration perspectives.

• Master's or PhD in Aerospace Engineering, Systems Engineering, Electrical Engineering, or a related discipline.
• 10+ years of experience in space systems engineering, including leading cross‑disciplinary and multi‑contractor projects.
• Proven experience in end‑to‑end space mission development, with emphasis on systems integration and technical leadership.
• Strong understanding of satellite and ground segment architectures, TT&C, payload operations, data downlink, and service chains.
• Familiarity with ECSS standards, MBSE approaches, and interface control across disaggregated systems.
• Excellent communication, negotiation, and documentation skills — able to align technically diverse partners toward common goals.
• Eligibility to obtain and maintain relevant national or NATO‑level security clearances.

• A strategic and technically authoritative role in high‑impact national and international space programs.
• Opportunity to shape mission‑critical infrastructure across the full upstream–downstream value chain.
• Collaborative environment with leading European and global space stakeholders.
• Competitive salary and benefits package, with relocation support if applicable.
• Professional autonomy and long‑term career growth in a future‑oriented sector.

• Experience managing or interfacing with space missions involving public‑private or multi‑actor collaboration (e.g., government, industrial consortiums).
• Exposure to dual‑use or defence‑related satellite missions.
• Knowledge of secure communications, ISR payloads, Earth observation data flows, or AI‑enabled data processing chains.
• Experience with frequency coordination, space policy, or national/international licensing and regulatory frameworks.
• Fluency in English and Hungarian; knowledge of other European languages is a plus.
