Spacecraft Systems Engineer

• Support the analysis of customer and mission needs to contribute to system requirement definition.

• Assist in maintaining spacecraft system architecture and ensuring interface consistency between subsystems.

• Contribute to the interdisciplinary design and verification activities of:

• Communication systems: telemetry, telecommand, RF links, modulation schemes, SDR platforms, antennas, and end-to-end space-ground architecture.

• OBDH: operational modes, data buses, TM/TC architecture, basic FDIR concepts.

• EPS (interface level): power budgets and subsystem electrical interfaces.

• AOCS (interface level): operational modes and subsystem interaction.

• Perform link budget calculations and support end-to-end communication architecture analysis (space segment to ground segment).

• Support trade-off analyses related to mass, power, and performance at system level.

• Contribute to troubleshooting and anomaly resolution under senior supervision.

• Prepare and maintain technical documentation: requirements, ICDs, verification plans, and design documentation.

Do you have experience in System architecture?, Do you have a Master's degree?, * Bachelor's or Master's degree in Telecommunications Engineering, Aerospace Engineering, Electrical or Electronic Engineering or related technical field

• 2-3 years in spacecraft systems engineering or in key subsystems (EPS, OBDH, Propulsion, or AOCS) or telecommunications satellites.
• Experience or knowledge in some of the following areas is required:

Telecommunications & Networks:

• RF communication systems and link budget analysis
• TT&C systems
• End-to-end communication architectures (space-to-ground)
• SDR platforms
• Antennas and RF subsystems
• Communication protocols such as CAN, SpaceWire, Ethernet, RS-4XX

Space systems (basic/intermediate level):

• TM/TC architecture
• OBDH systems and data buses
• Operational modes and redundancy concepts
• Basic understanding of EPS and AOCS interfaces

Valuable knowledge:

• Requirements management tools
• Familiarity with ECSS standards
• Basic understanding of FMECA and reliability analysis
• Experience with system simulation tools (MATLAB, Python or similar)
• Exposure to spacecraft integration and environmental testing (TVAC, vibration, EMC/EMI)
• Knowledge of ground segment architecture
• Hands-on experience with avionics hardware is valued but not mandatory.
• Ability to obtain and maintain a security clearance, if required.
