Spacecraft Systems Engineer

ARQUIMEA

Torrejón de Ardoz, Spain

Tasks to be performed:

• 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.

Required skills, experience and candidate profile:

• 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.
