Job summary

Infineon Technologies Americas Corp. seeks a Senior Staff Engineer to drive product definition and applications engineering for power MOSFETs (60 V and below) used in cordless power tools and battery-powered motor drives.

You will shape a differentiated portfolio, translate market needs into requirements and roadmaps, and provide hands-on leadership across simulation, hardware, and firmware to enable customer success.

Qualifications

• MS in Electrical Engineering with 4+ years or BS with 6+ years of progressive experience.
• Semiconductor product definition, technical marketing, or applications engineering experience with power MOSFETs or discrete power devices.
• Background in battery-powered motor drive applications (cordless tools, BLDC/PMSM inverters, low-voltage gate drive and protection).
• Strong fundamentals in power electronics, MOSFET switching behavior, SOA, and thermal design; ability to interpret schematics, layouts, and test/validation data.
• Hands-on PCB layout for power stages and firmware development (C/C++) for motor control.
• Hands-on motor drive testing and lab measurements using oscilloscopes, current probes, power analyzers, dynamometers, thermal imaging.
• Proficiency with simulation tools such as PLECS, SPICE, and SIMetrix.
• Ability to translate customer and market needs into product requirements, roadmaps, and business cases.
• Experience creating technical collateral and delivering trainings.
• Customer-facing experience, including design reviews and debug support.

Responsibilities

• Own product definition and positioning for low-voltage MOSFETs in cordless tools, garden/outdoor equipment, e-bikes, robotics, and other battery-powered BLDC/PMSM drives.
• Translate customer and market needs into requirements and roadmaps.
• Provide application leadership on inverter architectures, gate drive, and thermal design in compact, high-current packages.
• Perform electrical and thermal simulation using PLECS, SPICE, SIMetrix, and similar tools, correlating results with lab data.
• Design evaluation boards and reference designs, including PCB layout and embedded firmware (PWM, FOC/sensorless control, protection).
• Conduct hands-on motor drive testing, including double-pulse, efficiency, thermal, stall/locked-rotor, and EMI/ringing measurements.
• Provide customer support from design-in through production, including schematic/layout reviews, debug, MOSFET selection, and failure analysis.
• Partner with R&D and packaging on device and package trade-offs.
• Develop technical collateral (datasheets, application notes, user guides, models) and deliver trainings.
• Engage tool OEMs, Tier-1s, distributors, and ecosystem partners, and build competitive analyses and business cases with product marketing.
• Support validation and release readiness, ensuring data completeness, documentation quality, and alignment with relevant standards and qualifications.
