Job description

Please note: Due to mandatory security clearance requirements, only EU nationals are eligible for this position. This role is fully on-site, with activities primarily performed at ESA/ESTEC in Noordwijk and CGI’s office in Rotterdam.

Are you a System Engineer with an interest in secure satellite communications and emerging quantum technologies? Would you like to contribute to European programmes where space technology, cybersecurity and quantum communication come together?

CGI is looking for a QKD System Engineer to support ESA activities related to Quantum Key Distribution (QKD) and the European Quantum Communication Infrastructure (EuroQCI).

In this role, you will work at the forefront of secure European communications, supporting system engineering activities across space, ground and user segments and contributing to the development of future European quantum-secure communication capabilities.

Your role in our team

As a QKD System Engineer, you will provide system engineering support to ESA in relation to in-house activities for EuroQCI Entrusted Tasks.

You will work in a highly technical and international environment and contribute across multiple engineering domains, including:

  • Quantum Key Distribution (QKD)
  • Ground Segment Engineering
  • Satellite and Constellation Engineering
  • User Segment Engineering
  • Communication Engineering

Your responsibilities include:

  • Requirements engineering, analysis and consolidation.
  • Defining functional and physical system architectures.
  • Performing technical design trade-off analyses.
  • Defining and managing interfaces between systems and segments.
  • Supporting verification and validation planning.
  • Performing technical risk assessments.
  • Reviewing technical documentation and engineering deliverables from industrial partners.
  • Supporting ESA during key industrial milestones, including System Requirements Reviews (SRR), Preliminary Design Reviews (PDR), Critical Design Reviews (CDR) and Qualification Reviews (QR).
  • Preparing review comments and participating in technical review meetings.
  • Engaging in technical discussions with industrial partners to support the resolution of review items.
  • Preparing Technical Notes, Review Item Discrepancies, trade-off reports and verification and validation documentation.

Occasional travel to industrial sites may be required.

What you need to be successful

You combine a strong system engineering background with the ability to operate in complex, multidisciplinary technical environments.

You bring:

  • A Bachelor's or Master's degree in Systems Engineering, Aerospace Engineering, Telecommunications, Electrical Engineering, Physics or a related technical discipline.
  • Experience in system engineering within complex technical environments.
  • Knowledge of requirements engineering, system architecture, interfaces, verification and validation and technical risk assessment.
  • Experience participating in or supporting engineering lifecycle reviews such as SRR, PDR, CDR or similar technical milestones.
  • Strong analytical and problem-solving skills.
  • The ability to assess complex technical documentation and translate findings into clear recommendations.
  • Strong communication and stakeholder management skills.
  • Professional proficiency in English.

Experience or knowledge in Quantum Key Distribution (QKD), quantum communications, satellite communications, space systems, ground segments or secure communication systems is considered a strong plus.

Experience working with ESA, European institutions or within the aerospace, defence or other security-sensitive sectors is also considered a plus.
