Job Description

Job Description:Develop mathematical models and simulations for spacecraft electrical power system to support analyses required for power electronics hardware design and control software development, verification and troubleshooting.

Specific Responsibilities:
Define the technical requirements and architecture for the simulation system
Develop, validate, and maintain simulation models of electrical power system component including solar array, lithium ion battery, electric motor and controller, and power electronics
Use simulation to support analyses (transient response, stability, fault coordination) and trade studies
Support defining requirements for hardware component, control software and interfaces
Use simulation to assess potential issues before physical parts are available for testing
Develop interfaces for processor-in-the-loop and hardware-in-the-loop simulators
Prepare test plans, test procedures, test cases, conduct unit to system level testing, and write test reports
Support development of control algorithms for power electronic systems

This position can be filled at either the Principal Electrical Engineer or Sr. Principal Software Engineer level, depending on education level and years of experience.
