About the Company
Established in 2017, Infinite Orbits is a NewSpace company, based in Toulouse, pushing the boundaries of in-orbit services with cutting-edge spacecraft driven by its own Rendez-Vous solution, an advanced Autonomous Vision-Based Navigation Solution. IO has two generations of missions
"Orbit Guard" provides Inspection and Space Situational Awareness services in GEO. Our first, OG-1 was launched on 1 May 2023, the second is launching in 2025 and the third third launching in 2026.
"Endurance" is a docking service capable of extending the life of GEO telecom satellites, by taking over AOCS takeover for 5 years.
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.
What we offer
The opportunity to be part of an international team transforming the space industry.
A creative and innovative work environment where ideas turn into reality.
Competitive salary and benefits.
