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 lead the design, implementation and validation of Electrical Ground Support Equipment (EGSE) for GEO missions. You’ll ensure reliable spacecraft-to-ground communication, manage payload redundancy and mission-critical performance, and oversee both central checkout systems and external suppliers of high-reliability EGSE components.
Job Description
Design, develop and validate EGSE for RF interfaces (uplink/downlink, mod/demod, S- and Ku-Band conversion) and electrical systems (power interfaces, harnessing, stimulation units).
Integrate and operate PUS/CCSDS-compliant telemetry & telecommand over TCP/IP or EDEN-style links, using central checkout systems such as YAMS, SCOS-2000 or CCS5.
Define technical requirements and interface specifications for EGSE suppliers; evaluate proposals, manage FAT/SAT, change control and non-conformance reports through to delivery.
Interface with CCS teams to integrate SCOS MIBs, test databases and custom scripts; automate TM/TC sequences with TMTCCmd or equivalent tools.
Coordinate with payload teams to validate redundancy switching, fault detection and payload-specific test campaigns on closed-loop benches and simulations.
Ensure compliance with ECSS-E-ST-70-41, CCSDS standards and company AIT protocols; produce ICDs, test logs, EGSE schematics and configuration documentation.
Requirements
Bachelor’s or Master’s degree in Electrical, Aerospace or Systems Engineering.
Minimum of 8 years’ experience in EGSE system architecture for GEO telecom or scientific missions.
Proven track record integrating CCS systems and real-time PUS/EDEN (or equivalent) packet interfaces with onboard hardware.
Hands-on experience with SCOS-2000, YAMS or similar CCS integration tools.
Experience managing the full supplier lifecycle from specification through acceptance, including space-qualified harnessing and power interface validation.
Proficiency in Linux, Python scripting and network-protocol debugging.
Solid understanding of GEO mission constraints (latency, link budgets) and high-availability payload testing (cross-strap, redundancy logic).
Clear written and verbal communication skills in English for technical documentation and collaboration.
Preferred Qualifications:
Familiarity with deep-space protocols (SLE, CFDP) and RF lab work with S/K-band simulators.
Knowledge of spectrum licensing, ITU coordination or TT&C ground-station operations.
Experience with FDIR testing and fault-injection strategies.
If your background matches these qualifications and you’re ready to take ownership of EGSE for mission-critical GEO systems, we encourage you to apply.
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.
