Senior Electrical Architect H/F - Infinite Orbits

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.

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.
• 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.

Nice-to-Have Skills

• Experience in in-orbit servicing or rendezvous and proximity operations (RPO).
• Knowledge of fault-tolerant architectures and redundancy management.
• Experience in a NewSpace environment or agile development.
