Principle Power Electronics Engineer - LED Driver Systems

Job Description

Position Overview

Innovations in Optics is seeking a Principal Power Electronics Engineer to lead the design and development of advanced power electronics for high-performance LED illumination systems.

This role is focused on the architecture, design, analysis, and validation of high-current LED drivers, DC-DC converters, power management systems, and associated analog circuitry. The successful candidate will provide technical leadership for electrical designs from concept through production and will play a key role in defining the next generation of IOI products.

The ideal candidate has deep expertise in power electronics, strong analog design skills, and a proven track record developing robust products for demanding commercial, industrial, medical, aerospace, or defense applications.

While our products utilize embedded controllers for digital control and communications, firmware development is performed by dedicated software resources. This role requires sufficient embedded systems knowledge to define control requirements and collaborate effectively with firmware engineers but is not a firmware development position.

Key Responsibilities

Power Electronics Design

• Lead the design and development of high-current LED driver systems.
• Design DC-DC power converters and switch-mode power supplies.
• Develop current regulation architectures for precision LED applications.
• Analyze and design control loops, compensation networks, and power-stage stability.
• Optimize efficiency, thermal performance, reliability, and manufacturability.
• Perform worst-case, tolerance, and failure-mode analyses.

Analog & Hardware Design

• Design precision analog circuits for sensing, control, protection, and monitoring.
• Perform circuit simulation and design verification using industry-standard tools.
• Develop schematics and provide guidance during PCB layout and design reviews.
• Support prototype bring-up, debugging, and validation testing.
• Develop engineering documentation and design reports.

System Development

• Translate product requirements into electrical architectures and detailed designs.
• Work closely with firmware engineers to define digital control requirements and hardware interfaces.
• Collaborate with optical, mechanical, manufacturing, and quality teams.
• Support root cause analysis and corrective actions for field and production issues.
• Mentor junior engineers and provide technical leadership across projects.

Required Qualifications

Education

• Bachelor's degree in Electrical Engineering or related discipline.
• Master's degree preferred.

Experience

· Typically, 15+ years of relevant electrical engineering experience; candidates with fewer years and equivalent demonstrated technical depth and production ownership will also be considered.

· Extensive recent, hands-on experience personally designing and validating power electronics for production products.

· Demonstrated personal ownership of production power-converter designs, with the ability to explain design calculations, component selection, layout decisions, measured performance, and resolution of significant technical failures.

Technical Expertise

Power Electronics

• DC-DC converter design.
• Switch-mode power supply design.
• Control loop analysis and compensation.
• High-current power systems.
• Power system modeling and simulation.
• Thermal considerations for power electronics.

· Practical experience designing switching power converters for EMC/EMI performance and troubleshooting conducted and radiated emissions.

• Design-for-manufacturability and production support.
• Experience with Altium Designer or equivalent tools.

Preferred Qualifications

Candidates possessing several of the following will be viewed favorably:

• High-power LED driver design experience.
• Medical, industrial, aerospace, or defense electronics experience.
• Experience planning and supporting formal EMC compliance testing and resolving compliance failures.
• Thermal design of high-power electronic systems.
• Safety and regulatory compliance experience (IEC, UL, medical, industrial).
• Digital power control architectures.
• RS-485, Modbus, CAN, or other industrial communication systems.
• Production test system development.
• Experience working with STM
