About the role

As a Principal Engineer Technical Marketing at Infineon Technologies, you will lead the system-level design, development, and validation of DC/DC solutions and dynamic power supply architectures for AI data centers and telecom infrastructure. The position focuses on high-density conversion architectures, including resonant converters and wide-bandgap (GaN/SiC) semiconductor integration.

What you'll do

• Lead the conceptualization, design, and validation of high-density DC/DC converters and dynamic power supply architectures for high-transient AI inference and training workloads.
• Execute the system solution roadmap for AI data centers, authoring application notes, block diagrams, and technical value propositions.
• Integrate conversion methods such as resonant converters and wide-bandgap (GaN/SiC) semiconductors into HV-IBC architectures to improve efficiency and power density.
• Conduct teardowns and technical benchmarking of competitor topologies and components to refine system architectures and product features for telecom and server power supplies.
• Partner with digital marketing on system positioning and provide technical support, training, and technical inputs for customer RFIs and RFQs.

What you'll need

• B.S. in Electrical Engineering with 10+ years of experience, or M.S. in Electrical Engineering with 8+ years of experience in isolated and non-isolated DC/DC power converter development from simulation through PCB layout and validation.
• At least 5 years of experience in Application or System Engineering focused on telecom brick designs, rack power supplies, and AI infrastructure.
• Technical mastery of DC-DC topologies, magnetic component design, power semiconductor characteristics, and digital/analog controllers and gate drivers for Si and GaN.
• Familiarity with EMI/safety compliance standards and power management innovation trends.
• Ability to travel approximately 25% for customer meetings and technical engagements.
