Job summary

Infineon Technologies in El Segundo, CA seeks a Principal System Application Engineer to drive end-to-end development of DC/DC power converters for AI data-center applications. You will define robust architectures, simulate designs, and validate performance for high-density power systems.

Role requires expertise in power electronics, converter topologies, and controller design. Occasional travel and collaboration with marketing to position system-level advantages are expected.

Qualifications

• Lead end-to-end development of isolated/non-isolated DC/DC power converters; concept, block diagrams, simulation, schematic, PCB layout, bring-up, test and validation.
• Define and optimize converter topologies; select power semiconductors (Si, GaN) and design high-performance magnetics.
• Implement and tune digital and analog controllers and gate drivers for robust power management.
• Use industry-standard simulation and PCB design tools; produce clear, inclusive documentation and release packages.
• Ensure safety and EMI compliance; drive verification, certification readiness, and continuous improvement.
• Mentor teammates through training, inclusive collaboration, and rigorous design reviews; communicate effectively in English.
• Partner with customers and cross-functional teams on applications such as telecom bricks, rack power supplies, and AI systems; contribute Application/System Engineering expertise.

Responsibilities

• Execute the system solution roadmap to position Infineon as a leader in AI datacenter solutions, delivering application notes, solution boards, block diagrams, system value propositions, tech notes, and simulation models.
• Lead the design and validation of cutting-edge power electronics for high-density AI accelerators, including custom DC-DC converters and dynamic power architectures, emphasizing high efficiency, power density, and superior transient performance for inference and training.
• Explore and prototype advanced DC/DC conversion approaches using resonant topologies, wide-bandgap semiconductors (GaN, SiC), and HV-IBC architectures to push AI infrastructure performance.
• Define and evaluate system architectures and application requirements for server power supplies; conduct market research, product analysis, and teardowns to identify topologies and technical gaps.
• Create measurable technical value propositions and application-level collateral; assess new solutions (e.g., GaN); drive concept verification, design-in collateral, and inclusive technical customer support.
• Deliver technical trainings for diverse internal and external stakeholders; partner with Digital Marketing on inclusive system positioning, clear system block representations, and searchable web content.
• Provide technical inputs to RFIs/RFQs; contribute to feature definitions for digital & analog controllers and power stages; support customer engagements with occasional travel (about 25%).
