R&D Electrical Engineer – Digital Power Control & Topologies

Power Your Ideas. Build What’s Next.

At Astrodyne TDI, we develop power technologies and products that people depend on to enhance, protect, and save lives. With more than 60 years of experience in power supply design, our technology supports demanding applications across industrial, semiconductor, medical, aerospace, defense, and other critical markets.

We are looking for a motivated R&D Electrical Engineer at our Hackettstown, NJ location with a flexible hybrid schedule, who is excited about power electronics, digital control, and turning innovative concepts into working hardware on our Research & Development Team.

This is a hands-on engineering opportunity where you will contribute to the development of advanced switch-mode power supplies, digital control systems, and high-performance power conversion technologies. You’ll work across simulation, circuit design, embedded firmware, prototyping, laboratory testing, and troubleshooting while collaborating with experienced engineers on challenging real-world applications.

If you enjoy solving complex engineering problems, experimenting with new technologies, and seeing your designs move from the computer to the lab bench and ultimately into production, this could be the opportunity for you.

What You’ll Do

Design & Develop Advanced Power Electronics

• 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.

Develop Digital Power Control

• 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, Simulate & Analyze

• Model power converters and closed-loop control systems using SIMPLIS, SIMetrix, QSpice, or comparable simulation 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.

Build, Test & Troubleshoot

• 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.

Work with Advanced Power Technologies

• 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 as part of the overall design.

Support Design Verification & Compliance

• Participate in design verification, EMI/EMC troubleshooting, and product qualification activities.
• Support testing and documentation for applicable industrial, medical, military, and aerospace requirements, including MIL-STD-461 and UL/IEC 62368.
• Collaborate with Engineering, Operations, Quality, and other cross-functional teams to advance designs toward production.

What You Bring

Required Qualifications

• Bachelor’s degree in Electrical Engineering (BSEE) required; Master’s degree in Electrical Engineering or Power Electronics is a plus.
• 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, including 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 work collaboratively in a cross-functional engineering environment.

Preferred Qualifications

• 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 design tools.
• Familiarity with hardware-in-the-loop (HIL) 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.
