Senior Satellite Electrical Architect

Senior Satellite Electrical Architect

Infinite Orbits

Toulouse, France

About the Role

In this role, you will lead the definition and development of the spacecraft electrical architecture, with a strong focus on power generation, conditioning, storage, and distribution systems. You will play a key role in ensuring the performance, reliability, and robustness of our satellite platforms across all mission phases.

Job Description

• Define and maintain the overall electrical architecture of satellite platforms and subsystems.
• Lead the design and integration of spacecraft power electronics, including:
  • Power conditioning and distribution units (PCDU).
  • Battery management systems.
  • Solar arrays.
  • Solar Array Drive mechanisms (SADM).
• Drive technical trade-offs between performance, mass, reliability, thermal constraints, and manufacturability.
• Support system-level analyses including power budgets, fault tolerance, EMC/EMI compatibility, and redundancy strategies.
• Collaborate closely with systems, avionics, propulsion, software, AIT, and mission operations teams throughout the full development lifecycle.
• Define electrical interfaces and ensure subsystem compatibility and integration readiness.
• Contribute to design reviews (PDR, CDR, QR, AR) and technical decision-making.
• Support supplier selection, technical follow-up, and equipment qualification activities.
• Participate in anomaly investigations, root cause analysis, and corrective action implementation.
• Contribute to the continuous improvement of engineering methods, standards, and design practices.

Requirements

• Master’s degree or PhD in Electrical Engineering, Power Electronics, Aerospace Engineering, or related field.
• 5 to 12 years of experience in satellite electrical architecture and spacecraft power systems.
• Strong expertise in power electronics design for space applications.
• Proven experience with spacecraft electrical power systems (EPS), including battery technologies, solar arrays, and power distribution.
• Good understanding of ECSS standards and space qualification constraints.
• Experience working through full spacecraft development cycles, from concept to operations.
• Familiarity with radiation effects, derating, reliability analyses, and fault management strategies.
• Ability to lead complex technical discussions across multidisciplinary teams.
• Strong analytical, problem-solving, and communication skills.
• Professional working proficiency in English.

Nice to Have

• Experience in in-orbit servicing, rendezvous and proximity operations, or robotic platforms.
• Knowledge of high-reliability and fault-tolerant architectures.
• Experience with simulation and modelling tools for power systems.
• Previous involvement in New Space or fast-paced development environments.
