Communications & Data Handling Engineer – Small Satellite Missions

Job Description

We are looking for a Communications & Data Handling (C&DH) Engineer to join our Space Missions area, within the Communications & Data Handling (C&DH) team. The selected candidate will be responsible for the definition, specification, and verification of communication and data interfaces across the satellite platform, as well as supporting the electrical architecture and interface with the ground segment. You will work closely with the Systems Engineering team, as well as engineers from Mechanical, Mission Analysis, and Platform Product areas to ensure full system integration and mission readiness.

Position Tasks and Responsibilities

Main responsibilities include:

• Selection and definition of on-board communication subsystems (OBCs, TTC modules, radios, antennas, etc.).
  

• Definition of the logical architecture, including data buses, protocols, and internal communications structure.
  

• Specification of the electrical architecture, including power interfaces, grounding schemes, and subsystem connectivity.
  

• Preparation of Interface Control Documents (ICDs) to ensure compatibility across systems.
  

• Specification of harnessing and connector layouts in collaboration with mechanical and system engineering.
  

• Contribution to space-to-ground communication planning, including telemetry/downlink strategy and data routing.
  

• Supporting ground segment definition to ensure compatibility with TTC equipment and mission needs.
  

• Contribution to orbit-spectrum coordination activities and support in ITU-related documentation.

• Performing and validating link budgets to ensure RF performance and coverage.

Candidate qualifications and skills

We are looking for a telecommunications or electrical engineer with a strong technical foundation and interest in space systems.

• Degree in Telecommunications Engineering, Electrical Engineering, or related fields.
  

• At least 2 years of relevant experience in:
  

  • OBCs, TTC subsystems, radios, antennas, and satellite communications.
    

  • Data buses and communication protocols (CAN, I²C, UART, SPI, etc.).
    

  • Electrical design, power interfaces, grounding, and EMC considerations.
    

• Familiarity with interface definition and documentation (ICDs).
  

• Knowledge of RF concepts and ability to work on link budgets.
  

• Ability to collaborate across disciplines, communicate clearly, and document technical work.
  

• Fluent English, written and spoken.

Nice to have

• Experience with small satellite platforms or cubesats.
  

• Knowledge of ECSS standards.

• Familiarity with spectrum regulations and ITU filing processes.

• Experience in hardware procurement or specification of EGSE and electrical test setups.
