• At least 5 years of professional experience in space electrical architecture, with proven expertise in EMC, ESD, and grounding & bonding.
• Experience on at least one satellite mission completed from end to end.
• Proficiency in applicable ECSS standards (EMC, ESD, grounding and bonding).
• Experience in conducting equipment electrical compatibility reviews and analyzing ICDs.
• Experience in EMC, ESD, and ground continuity testing at both equipment and system levels during AIT campaigns.
• Solid background in power electronics and space electrical distribution.
• Understanding of space environment effects on electrical systems (electrostatic charging, radiation, derating).
• Ability to lead cross-functional topics and interact with suppliers and partners.
• Excellent technical communication skills, both oral and written, in professional English.
• Nationality: French nationality is mandatory due to project requirements.

Responsabilités

• Define and maintain the overall electrical architecture of the satellite (generation, storage, distribution, protection).
• Establish power budgets and distribution architectures.
• Define electrical protection requirements and fault tolerance strategies.
• Guarantee energy availability under LEOP, safe mode and eclipses.
• Define and maintain grounding and bonding scheme; develop ESD protection plan.
• Define EMC requirements and margins; lead interface reviews with suppliers.
• Develop EMC/ESD/grounding test plans and troubleshoot anomalies.
• Coordinate architecture choices with mechanical, thermal, avionics, flight software, RF and computer vision teams.

Description du poste

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.

"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

The Electrical Architect leads the electrical architecture of the satellite as a whole (platform and payload), with a particular focus on the electrical integrity of the vehicle: protection against electrostatic discharge (ESD), electromagnetic compatibility (EMC), grounding and bonding schemes, and supplier equipment electrical compatibility. He or she ensures end-to-end electrical consistency across Infinite Orbits programs in close interface with system architecture, mechanical, thermal, and other subsystems.

Job Description

Electrical Architecture & Power

Define and maintain the overall electrical architecture of the satellite (generation, storage, distribution, protection), ensuring end-to-end consistency across all subsystems.

Establish power budgets and distribution architectures.

Define electrical protection requirements (overloads, short circuits, current limiters) and fault tolerance strategies.

Guarantee energy availability under all conditions (LEOP, safe mode, eclipses).

Electrical Integrity — ESD, EMC, Grounding & Bonding

Define and maintain the satellite grounding and bonding scheme: ground topology, structural connections, signal and power returns.

Develop the Electrostatic Discharge (ESD) control plan, including charge/discharge analysis in space environment, protection of internal/external surfaces, and static dissipation requirements.

Define the budget and Electromagnetic Compatibility (EMC) requirements of the satellite: conducted and radiated emissions and susceptibility, EMC margins.

Lead Electrical Interface Compatibility Reviews for equipment and verify supplier interfaces compliance with ICDs.

Develop EMC, ESD, and ground continuity test plans, and troubleshoot associated anomalies.

Cross-functional

Evaluate space-qualified electrical components and equipment, and manage supplier relationships (specifications, EMC/ESD/grounding compliance tracking).

Coordinate architecture choices with mechanical, thermal, avionics, flight software, RF, and computer vision teams.

Participate in design reviews (SRR, PDR, CDR, QR) and associated technical trade-offs, particularly regarding EMC/ESD/grounding aspects.

Supervise integration, qualification testing, and functional electrical validation during the AIT phase.

Conduct technology monitoring and propose architecture evolutions.

Requirements

Engineering degree (Master's level / Bac+5) in power electronics, electrical engineering, EMC, or aerospace, or equivalent; PhD appreciated.
