Electrical System Engineer - AIT Ground Segment

Electrical System Engineer - AIT Ground Segment

Infinite Orbits

Toulouse, France

About the Role

Based in Toulouse within our Spacecraft AIT/Ground Segment Engineering department, you will own the end-to-end electrical ground-support systems for GEO missions. You’ll lead the specification, design, procurement and validation of EGSE hardware (including SCOE/RF test channels and umbilicals), and support both AIT campaigns and on-orbit operations.

Job Description

• Define and translate spacecraft interface requirements into EGSE/HW specifications (power interfaces, harnessing, umbilical connectors).
• Architect and develop RF test benches (S- and Ku-Band up/down converters, modulation/demodulation units, loop-back simulators) and SCOE channels.
• Write technical requirements for EGSE suppliers; evaluate proposals, drive FAT/SAT activities, and manage change control and non-conformance through to closure.
• Install, configure and troubleshoot EGSE hardware during spacecraft AIT campaigns and launch-site operations.
• Provide Tier-2 support for electrical test sequences, instrumentation wiring checks and fault-finding procedures.
• Produce EGSE schematics, wiring diagrams, ICDs, test procedures and configuration baselines.
• Ensure adherence to ECSS-E-ST-70-41, relevant RF-SCOE guidelines and internal AIT protocols.

Requirements

• Bachelor’s or Master’s degree in Electrical, Aerospace or Systems Engineering.
• 8+ years’ hands-on experience in EGSE system architecture and lab operations for GEO telecom or scientific missions.
• Demonstrated expertise with SCOE/RF test equipment (up/down converters, spectrum analyzers, signal generators) and EGSE power interfaces.
• Proven track record in electrical harness design, power distribution and connector qualification for space applications.
• Strong background in electrical safety, grounding/EMC practices and high-voltage test procedures.
• Experience specifying, procuring and qualifying space-grade cabling, umbilicals and RF hardware.
• Ability to lead supplier FAT/SAT cycles and manage non-conformance through to closure.
• Excellent problem-solving skills in lab-based troubleshooting during high-stakes AIT campaigns.
• Clear written and verbal communication skills in English for technical documentation and collaboration.

Preferred Qualifications:

• Familiarity with RF lab automation (LabVIEW, PXI, or equivalent).
• Experience with FDIR strategies, fault-injection and redundancy-validation test campaigns.
• Knowledge of ECSS-E-ST-10, ITU coordination processes or ground-station RF licensing.
• Prior work managing calibration schedules and MCO workflows in a high-reliability environment.
