Senior Satellite 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.


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.
