Principal Engineer Applications

About the role

Join a team focused on driving Infineon’s leadership in AI data center and telecom solutions. You will execute the system solution roadmap, design and validate state-of-the-art power electronics subsystems for high-density AI accelerators, and explore innovative DC/DC power conversion methods to advance AI infrastructure.

Responsibilities

• Lead the conceptualization, design, and validation of power electronics subsystems for AI accelerators, including custom DC-DC converters and dynamic power supply architectures.
• Develop high-efficiency, high-density designs to meet the transient power demands of AI inference and training tasks.
• Explore novel DC/DC power conversion methods, such as resonant converters, wide-bandgap semiconductors (GaN, SiC), and HV-IBC architectures.
• Evaluate and document system architecture and application requirements for telecom and server power supplies.
• Conduct market research, teardowns, and analysis of competing systems to understand topology, content, and technical challenges.
• Define quantifiable technical value propositions and collateral for applications, including new solutions like GaN.
• Oversee system concept verification, design-in collateral, and technical customer support at the application level.
• Provide technical training on system-level topics to internal and external stakeholders.
• Collaborate with the digital marketing team to ensure accurate system solution positioning, block representation, and searchability on Infineon’s website.
• Contribute technical inputs to customer proposals (RFIs/RFQs) and product feature definitions for digital/analog controllers and power stages.
• Occasional travel (10-15% of the time) for customer meetings in San Jose, CA.

Requirements

• M.S. in Electrical Engineering with a minimum of 8 years of experience, or B.S. in Electrical Engineering with a minimum of 10 years of experience in power electronics, with a focus on isolated/non-isolated DC/DC power converters.
• Extensive knowledge of DC-DC converter topologies, magnetic components, and power semiconductor characteristics.
• Experience developing DC/DC power converter solutions, including concept, block diagrams, simulation, schematic, PCB layout, debugging, testing, and validation.
• Proficiency with simulation and PCB design tools.
• Experience mentoring junior engineers, conducting design reviews, and providing training on power electronics topics.
• Strong verbal and written communication skills in English.

Desired Skills

• Experience with digital and analog controllers and gate drivers for power management (Si & GaN).
• Expertise in magnetics design and optimization.
• Familiarity with safety and EMI compliance standards.
• Advanced degree or doctorate in electrical engineering, power electronics, or a related field.
• Profound expertise in telecom brick designs, rack power supplies, and artificial intelligence applications.
• At least 5 years of relevant work experience in application or system engineering, ideally at an OEM, Tier 1, or engineering service provider.
