Job description

Electrical Power Systems Architect - Space

EVONA is exclusively partnered with a venture-backed space company developing next-generation orbital energy systems. They are seeking a Senior Power Electronics / Electrical Power System (EPS) Architect to lead the design of a high-voltage (~400V) spacecraft power system supporting mission subsystems and high-power payloads.

This role owns the end-to-end EPS architecture - from solar array interfaces through regulation, storage, protection, and distribution -and works closely with electrical, controls, and payload teams to close technical risk and drive integration.

Key Responsibilities

• Own detailed electrical architecture for a high-voltage spacecraft power system
• Define power generation, storage, regulation, and distribution strategies
• Lead design of S3R-based solar array interfaces, battery regulation, bus conversion, and HV/LV distribution
• Select DC–DC converter topologies (isolated/non-isolated)
• Define over-current, over-voltage, arc fault, and isolation schemes
• Specify derating, thermal margins, EMI/EMC compliance
• Support schematics, layout guidance, and design reviews

High-Voltage & Space Environment

• Define insulation, grounding, and coating strategies
• Ensure compliance with aerospace HV standards (e.g., NASA-STD-4005)
• Lead system-level FMEA and fault response design
• Support integration with control systems, avionics, and high-power payloads
• Define verification strategy and support hardware bring-up and testing

Required Qualifications

• BS/MS in Electrical Engineering or related field
• 10+ years in power electronics and/or spacecraft EPS design
• Experience with high-voltage DC systems, power conversion, and system-level architecture
• Strong knowledge of solar array regulation (S3R/MPPT), battery integration, and fault-tolerant distribution
• Experience taking hardware from concept through test
• Radiation and space-environment design awareness
