Power Electronics Engineer-All Levels

We are looking for a Power Electronics Engineer to design and build high-performance power electronics for autonomous platforms. You will own power conversion circuit design, PCB layout, hardware bring-up, and validation, working closely with firmware, mechanical, and systems teams. The role spans from schematic capture through field integration, with a focus on high-efficiency, high-reliability applications.

Responsibilities

• Design and develop power conversion circuits—including switch-mode DC/DC converters (buck, boost, flyback, PSFB), gate driver stages, and motor drive circuits—using SiFET and GaN FET technology for high-efficiency, high-reliability applications.
• 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.
• 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.
• Run SPICE-based simulations (LTspice, PSIM, or SIMPLIS) for power stage design, transient analysis, and control loop modeling; perform thermal analysis to validate designs before fabrication.
• Lead EMI/EMC debugging and design to meet radiated and conducted emissions requirements; support qualification testing against applicable military or commercial standards.
• Collaborate with firmware engineers to define and validate digital control interfaces for power and motor drive systems, and work with mechanical teams to ensure thermal and structural integration.
• Maintain thorough design documentation including schematics, layout rationale, simulation results, BOM, and test protocols.

Requirements

• 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—phase current sensing, gate driver selection, protection circuitry—from schematic through bring-up.
• 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, and high-current trace routing.
• Proficiency with SPICE-based simulation tools (LTspice, PSIM, SIMPLIS, or equivalent) for power circuit validation and control loop analysis prior to fabrication.
• Hands-on EMI/EMC debugging experience; ability to identify root causes of conducted and radiated emissions and implement effective design fixes.
• Skilled use of oscilloscopes, power analyzers, logic analyzers, and bench power supplies for hardware characterization, bring-up, and debug.
• Bachelor’s or Master’s degree in Electrical Engineering or closely related field.

Nice to have

• 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—custom inductor and transformer specification, core selection, and winding layout.
• Thermal management experience: 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 non-negotiable.
• Experience taking a power electronics design through full EMI/EMC certification (class A or B radiated and conducted).
• Knowledge of communication and control protocols common in embedded systems: CAN, SPI, I2C, UART.

Benefits

• Competitive salary
• ACS Equity Package
• Health, Dental, Vision Insurance
• Paid Time Off
