- Define power converter architectures and key system components for emerging AI and data center power solutions.
- Provide switching power supply design support and technical guidance for applications based on Power Integrations products.
- Develop reference designs and application solutions that demonstrate performance, efficiency, and system value for AI and data center power architectures.
- Collaborate with product development teams and customers to solve complex technical challenges, evaluate design tradeoffs, and optimize system performance, density, and reliability.
- Serve as a technical expert and provide advanced application support to customers worldwide.
What you'll need
- Bachelor’s or Master’s degree in Electrical Engineering, or foreign equivalent.
- Minimum 8-10 years of relevant industry experience.
- Hands-on experience and deep expertise in high-density, high-frequency power converter design, including server power applications above 3 kW.
- Strong familiarity with power supply topologies including active power factor correction circuits, phase-shifted and LLC resonant converters, and buck, boost, buck-boost, and flyback converters.
- Expert knowledge of high-frequency magnetics design.
- Ability to perform complex calculations, including worst-case analysis, for circuits.
- Experience with tools such as MATLAB, Excel, and simulation software such as SIMPLIS/LTspice/PLECS.
- Strong hands-on capability and experience using lab equipment to test high-frequency switching power supplies.
- Excellent written and verbal communication skills, including experience creating specifications, technical reports, and test plans or instructions.
- Knowledge of relevant industry standards and system architectures.
Nice to have
- Experience developing firmware in C/C++ for embedded controllers in power supply applications, along with the ability to provide firmware guidance.
- Experience using finite element tools such as ANSYS.
- Experience designing power supplies/power converters from concept to production and supporting post production.
- Knowledge of communication protocols such as I2C and PMBus.
- Familiarity with tools for debug of power converters with embedded controllers.
