Leveraging 4iG's strong foundation in technology and infrastructure, the company is building a regional ecosystem that combines innovation, industrial capability, and strategic partnerships.Our focus spans five key domains : Space, Aero, Land Systems, Weapons & Ammunition, and Cyber & Digital. Across these areas, we develop and deliver cutting-edge solutions ranging from satellite systems and unmanned aerial technologies to armored vehicles, advanced weapons, and defence digitalization.With a mission to become a leading space and defence integrator in Central and Eastern Europe, 4iG Space & Defence is shaping the future of regional security and technological independence while expanding its reach to international markets.

In order to achieve our common goals, we count on you

  • 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.

What you will need for successful work

  • 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.

    • What we offer

  • 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.

    • What we are happy about

  • Experience managing or interfacing with space missions involving public-private or multi-actor collaboration (e.g., government, industrial consortiums).
  • Exposure to dual-use or defense-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.
