Job description

We are looking for a Power Electronics Engineer with deep expertise in power conversion hardware, PCB design, and electromechanical systems. You will design and build the high-performance power electronics that drive autonomous platforms—from schematic capture and board layout through bring-up, validation, and field integration—working closely with firmware, mechanical, and systems teams.

PCB Design & Hardware Development

• Own schematic capture and multi-layer PCB layout in Altium Designer for power and mixed-signal boards, with rigorous attention to power loop minimization, EMC, thermal management, and signal integrity.
• Work with mechanical teams to ensure proper thermal and structural integration of power electronics into electromechanical systems.

Hardware Bring-Up, Validation & Test

• Lead hardware bring-up from power-on through closed-loop validation; characterize switching waveforms, debug gate driver behavior, and verify power stage performance using oscilloscopes, power analyzers, and logic analyzers.
• Lead EMI/EMC debugging and design to meet radiated and conducted emissions requirements; support qualification testing against applicable military or commercial standards.
• Maintain thorough design documentation including schematics, layout rationale, simulation results, BOMs, and test protocols.

Required Qualifications

• Bachelor's or Master's degree in Electrical Engineering or a closely related field.
• 3+ years of hands‑on experience designing switch‑mode power conversion circuits, including topology selection, magnetics design, and gate driver implementation for SiFET or GaN‑based systems.
• Demonstrated experience with BLDC or PMSM motor drive hardware—including phase current sensing, gate driver selection, and protection circuitry—from schematic through hardware bring‑up.

Technical Skills

• Strong command of Altium Designer (or comparable EDA tool) for multi‑layer mixed‑signal and power PCB design.
• Solid understanding of EMC design practices, power loop layout, thermal considerations, and high‑current trace routing.
• Proficiency with SPICE‑based simulation tools (LTspice, PSIM, SIMPLIS, or equivalent) for power circuit validation and control loop analysis.
• Hands‑on EMI/EMC debugging experience with the ability to identify root causes of conducted and radiated emissions and implement effective design fixes.
• Skilled in the use of oscilloscopes, power analyzers, logic analyzers, and bench power supplies for hardware characterization, bring‑up, and debug.

Preferred Qualifications

• Experience with digitally controlled power converters using DSP or microcontroller platforms (e.g., TI C2000, STM32), including implementation of digital compensators or current sharing algorithms in Verilog or C.
• Familiarity with magnetics design, including custom inductors, transformer specification, core selection, and winding layout.
• Thermal management experience, including heat sink selection, thermal interface material specification, and steady‑state thermal simulation.
• Background in high‑reliability, defense, aerospace, or space electronics where design verification, documentation, and environmental qualification are critical.
• Experience taking a power electronics design through full EMI/EMC certification (Class A or Class B radiated and conducted emissions).
• Knowledge of embedded communication and control protocols, including CAN, SPI, I2C, and UART.
