Project Engineer I

Responsibilities

• Analyze, model, simulate, design, and develop switch-mode power supplies ranging from 10W to 2000W, from initial concept and circuit design through prototyping, testing, validation, and production.
• Design and develop cost-effective, high-performance AC/DC power conversion circuits for next-generation power supply products.
• Design and develop single-phase and polyphase, high-frequency, offline switch-mode converters and inverters for desktop computing, server, telecommunications, and motor drive applications.
• Optimize power supply designs for conversion efficiency, power density, reliability, thermal performance, and overall cost.
• Perform circuit simulations and design calculations using PSpice, Mathcad, and other engineering tools to evaluate circuit performance and validate design concepts.
• Conduct electrical testing, troubleshooting, and root-cause analysis to identify design issues and implement corrective actions.
• Evaluate component selection, circuit topologies, and design trade-offs to meet product performance, safety, and reliability requirements.
• Collaborate with cross-functional teams, including engineering, manufacturing, and quality, to support product development, design improvements, and production implementation.
• Prepare and maintain technical documentation, design specifications, test reports, and engineering records.
• Support prototype development, design verification, product qualification, and troubleshooting of existing power supply products as needed.
• Stay current with developments in power electronics, circuit design technologies, and industry requirements to support continuous product improvement.
• Travel domestically and internationally as required to support engineering projects, customer needs, and business operations.

Qualifications

• Bachelor's degree in Electrical Engineering or a related engineering discipline.
• Two or more years of experience in analog circuit design or power electronics development preferred; new graduates with relevant academic projects or technical experience are welcome to apply.
