Avionics System Engineer - Electrical Power System

Here at The Exploration Company, we are developing, producing, and operating Nyx, a modular and reusable space orbital vehicle that can eventually be refuelled in orbit and that can carry cargo - and potentially humans in the longer run.

• System Architecture & Design
• Define the Electrical Power System architecture in coordination with system engineering and mission requirements.
• Size and specify solar arrays, batteries, and power conditioning/distribution units.
• Ensure optimal power generation, storage, and distribution strategy across all mission phases and failure scenario and failure scenario
• Component Selection & Specification
• Evaluate and select flight-qualified components: solar cells, battery design, power conversion and protection elements.
• Support the design of power conditioning and distribution units
• Generate technical specifications
• Analysis & Simulation
• Conduct worst-case, reliability, and redundancy analyses in accordance with ECSS/NASA standards.
• Integration & Testing
• Define and execute Electrical Power System verification and validation plans (unit, subsystem, and system levels).
• Support integration of Electrical Power System with other subsystems of the spacecraft.
• Participate in environmental testing: vibration, thermal vacuum, EMC.
• Project & Supplier Coordination
• Interface with suppliers for COTS and internal teams for in-house designed power system components.
• Support project development logic, planning, risk assessment, and technical reviews (PDR, CDR, TRR).
• Documentation & Standards Compliance
• Produce detailed documentation for design, analysis, test procedures, and compliance reports.
• Ensure compliance with space-grade standards (NASA-STD, ECSS)
• Contribute actively to reviews with customers and certification authorities for the Electrical Power System.

• Master’s degree in Electrical Engineering, Aerospace Engineering, or related field.
• Minimum 3–5 years of experience in spacecraft Electrical Power System or avionics system development.
