Requirements

Bachelor's degree in Electrical Engineering required
2-5 years of hands-on experience in switch-mode power supply design, power electronics, and/or digital control.
Practical experience with Texas Instruments C2000 microcontrollers, Code Composer Studio, and C2000Ware.
Solid understanding of classical and digital control concepts, including peak current mode, average current mode, and voltage mode control.
Experience modeling power converters and closed-loop control systems using SIMPLIS, SIMetrix, QSpice, or comparable tools.
Familiarity with high-frequency magnetic components, including inductors and transformers.
Understanding of PCB layout considerations for high-frequency power electronics.
Strong laboratory troubleshooting, analytical, and problem-solving skills.
Ability to communicate technical concepts effectively and collaborate in a cross-functional engineering environment.

Nice To Haves

Master's degree in Electrical Engineering or Power Electronics is a plus.
Experience with SiC and/or GaN wide-bandgap semiconductors.
Experience with high-voltage power-conversion topologies.
Proficiency with Cadence OrCAD Capture, Allegro PCB Editor, or comparable schematic and PCB tools.
Familiarity with hardware-in-the-loop testing or rapid-prototyping platforms.
Experience with EMI/EMC testing and troubleshooting.
Experience developing power supplies for regulated, safety-critical, medical, aerospace, or defense applications.

Responsibilities

Design, prototype, and evaluate switch-mode power converters, including PFC, resonant LLC, phase-shifted full-bridge, buck, and boost topologies.
Contribute to power architecture, circuit design, component selection, and design optimization.
Develop high-reliability power conversion solutions for demanding industrial, medical, aerospace, and defense applications.
Implement real-time digital control loops for switch-mode power stages using Texas Instruments C2000 microcontrollers.
Develop and test C/C++ firmware using TI C2000 peripherals, including ePWM, Type IV PWM, CMPSS, and high-speed ADCs.
Optimize control-loop performance, transient response, stability, and protection functions.
Model power converters and closed-loop control systems using SIMPLIS, SIMetrix, QSpice, or comparable tools.
Perform transient analysis, AC sweeps, control-loop stability analysis, and frequency-response evaluation.
Validate continuous-to-discrete control-loop transitions and use simulation results to guide hardware development.
Take designs from simulation and schematic through prototype development and laboratory validation.
Conduct electrical, thermal, efficiency, stress, and reliability testing.
Troubleshoot complex power-conversion and control issues using oscilloscopes, electronic loads, power analyzers, network analyzers, and other laboratory equipment.
Analyze test results and translate findings into practical design improvements.
Support gate-driver design and switching-stage optimization.
Evaluate switching losses and performance of MOSFET, SiC, and GaN power devices.
Consider high-frequency magnetics, PCB layout, parasitics, thermal management, and EMI throughout the design.
Participate in design verification, EMI/EMC troubleshooting, and product qualification activities.
Support testing and documentation for applicable requirements, including MIL-STD-461 and UL/IEC 62368.
Collaborate with Engineering, Operations, Quality, and other teams to advance designs toward production.
