About this Technical Lead – Satellite QKD System (LEO) role at Leonardo

Leonardo · Onsite · ES - Madrid

Job Description:

We are looking for a Technical Lead to join a cutting-edge space project focused on Quantum Key Distribution (QKD) in Low Earth Orbit (LEO).

In this role, you will act as the technical authority on behalf of TPZ, ensuring end-to-end system coherence across space, ground, and user segments, while leading requirements engineering, system design, and validation activities under the ECSS framework.

You will play a key role in shaping the technical backbone of a highly innovative mission, contributing directly to secure communications of the future.

Key Responsibilities

Systems Engineering

  • Lead and oversee system engineering activities, including high-level design of the complete LEO QKD system.
  • Ensure technical and functional consistency across space segment (platform and quantum payload), ground segment (GCS, OGS, KMS), and user segment.
  • Define and maintain the end-to-end system architecture and product tree.

Requirements Engineering

  • Lead the identification, analysis, and consolidation of mission and subsystem requirements (Ground Control Segment).
  • Coordinate the definition of preliminary cybersecurity requirements across all segments.
  • Support the definition of Mission Simulator requirements.

Design & Development

  • Lead the design of Ground Control Segment subsystems and the integration of the Quantum Uplink Node and its interfaces.
  • Contribute to the Mission Simulator design.

Integration, Verification & Validation (IVV)

  • Define and supervise IVV plans at system and subsystem levels.
  • Oversee verification documentation and test plan development.
  • Ensure consistency between requirements, design, simulations, and test results.

Operational Concept (CONOPS)

  • Lead the definition and evolution of the end-to-end operational concept.
  • Oversee key management processes, including generation, distribution, and demand planning.
  • Coordinate mission planning and orchestration across space and ground segments.

Technical Coordination

  • Act as the cross-functional technical authority within an international consortium (industry, agencies, and research centers).
  • Manage system interfaces and technical trade-offs at a global level.

Required Skills & Knowledge

Space Systems Engineering

  • Expertise in ECSS standards and methodologies (New Space context preferred).
  • Experience in LEO mission design and analysis.
  • Strong understanding of complex end-to-end space system architectures.

Quantum & Optical Communications

  • Knowledge of Free Space Optical Communications (FSOC).
  • Understanding of QKD systems and quantum communication principles.
  • Familiarity with secure communication standards and European programs (EuroQCI, IRIS2).

Ground Segment & Operations

  • Experience with Mission Control Systems (MCS).
  • Knowledge of mission planning and optimization.

IVV & Requirements Management

  • Strong background in validation and verification of complex systems.
  • Experience with requirements traceability tools and methodologies.
  • Ability to define test scenarios and acceptance criteria.

Cybersecurity

  • Understanding of system-level cybersecurity in space and communications systems.
  • Experience applying “security-by-design” principles.
  • Knowledge of QKD-related security concepts.

Experience Required

  • Minimum 10 years of experience in Systems Engineering for space missions or complex systems.
  • Proven experience leading requirements and IVV activities in multi-stakeholder environments.
  • Background in mission control systems design and operations planning.
  • Experience in optical communications, satcom, or secure systems.
  • Previous participation in international consortia (industry, agencies, research institutions).

Why this role matters

  • Drive the technical coherence of an end-to-end LEO QKD system.
  • Reduce integration and technological risks in an innovative IOD mission.
  • Enable the transition from early design to future operational systems.
  • Take ownership of the Ground Control Segment specification and design.
