Senior Motor and Power Controls Engineer

About the role

A New Paradigm For Space Operations.

What You'll Do

As a Senior Power Electronics Engineer, you will own the design, development, integration, and testing of power electronics and electrical power systems for Space Kinetic's payload and spacecraft. You will lead the development of high-performance power conversion, distribution, and control electronics that enable demanding electromechanical systems and other flight-critical hardware.

You will work across electrical, mechanical, controls, software, and systems engineering to translate system-level requirements into robust electrical architectures and flight-ready hardware. This is a highly hands-on engineering role requiring technical leadership, sound engineering judgment, and the ability to take complex power electronics from initial concept through qualification and flight.

Job Responsibilities

• Lead the architecture and design of power electronics for spacecraft and electromechanical systems.
• Design high-power switching electronics, DC/DC converters, motor drives, and power distribution systems.
• Develop power architectures incorporating energy storage, battery management, protection, and distribution.
• Perform electrical, thermal, efficiency, transient response, and component derating analyses.
• Select and qualify power semiconductors, gate drivers, magnetics, and other critical components.
• Develop schematics, PCB layouts, electrical interfaces, and hardware specifications.
• Lead hardware bring-up, debugging, characterization, and qualification testing.
• Collaborate with controls and embedded systems engineers on power electronics interfaces and control strategies.
• Support vehicle integration, environmental testing, and flight hardware development.
• Provide technical leadership and mentorship while remaining hands-on with design and development.

What It Takes

• Bachelor's degree in Electrical Engineering, Computer Engineering, Controls Engineering, or a related field.
• 7+ years of experience in embedded systems, motor controls, or power controls.
• Strong embedded firmware development skills in C/C++
• Experience with BLDC/PMSM motor control, commutation, and closed-loop control
• Experience with microcontrollers, PWM, ADCs, and real-time embedded systems.
• Experience integrating firmware with motor drives and power electronics.
• Must be a U.S. Person due to required access to U.S. export-controlled information or facilities.

What We'd Love

• Master's degree in Electrical Engineering or a related field.
• Experience with Field-Oriented Control (FOC) and motor-control optimization.
• Experience with isolated DC/DC converters, battery charging, and high-voltage power systems.
• Familiarity with CAN, SPI, I2C, UART, and embedded communication protocols.
• Experience with RTOS, FPGA-based controls, or hardware-in-the-loop testing.
• Experience developing controls for aerospace, spacecraft, robotics, or other high-performance electromechanical systems.
