Power Electronics Engineer-All Levels

Company Overview
ACS (Allen Control Systems) is a defense technology company building precision robotic systems for the United States and its allies. Founded by two former U.S. Navy electrical engineers with deep experience in robotics and software, ACS brings together AI, computer vision, precision motion, and advanced hardware to solve complex defense challenges across land, air, and maritime environments.

Our flagship product, Bullfrog, is an autonomous precision weapon system that transforms existing weapons into highly accurate counter-drone systems — giving warfighters a scalable, cost-effective response to one of the fastest-growing threats on the modern battlefield. Bullfrog is deployed with U.S. forces, and ACS works with organizations throughout the U.S. military and national security community.

Following a $200 million Series B at a $2.2 billion valuation, ACS is rapidly expanding manufacturing, accelerating Bullfrog deployments, and developing the next generation of autonomous battlefield systems. This is an opportunity to join a proven, fast-moving team and help scale technology with direct, real-world impact on national security.

ACS is headquartered in Austin, Texas, with additional operations in Alexandria, Virginia; Mountain View, California; and Huntsville, Alabama. For more information, visit allencontrolsystems.com.

About The Role

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 our autonomous platforms from schematic capture and board layout through bring-up, validation, and field integration-working closely with firmware, mechanical, and systems teams.

We’re hiring across multiple experience levels, including:

• Associate Engineer

• Engineer

• Senior Engineer

• Staff Engineer

• Senior Staff Engineer

  Your title and level will be determined based on your experience, skills, and the scope of responsibility appropriate for the role.

What You’ll Do

• 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.

What You’ll Need

• 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.

You’ll Stand Out

• 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.

What We Offer

• Competitive salary

• ACS Equity Package

• Health, Dental, Vision Insurance

• Paid Time Off
