As a Principal Engineer Digital Systems at Infineon, you will contribute to the expansion of the team by performing Systems Concept Engineering for Mixed Signal ICs, focusing on efficient power delivery in AI data centers. You will collaborate with application engineering, analog and digital IC design teams to develop optimal system solutions that achieve industry-leading performance. Your responsibilities will include defining microcontroller-based digital architecture for multiphase power controllers, firmware architecture, digital and mixed signal chip architecture, digital signal processing, control system design, and modeling. You will evaluate system specifications and functional requirements, draft IC top-level functional requirements and sub-block specifications, and execute proof of concept through system modeling/simulations and FPGA-based hardware prototyping.
