• Strong knowledge of power electronics topologies used in server and AI data center power systems.

Responsibilities

• Perform direct high-voltage semiconductor testing and characterization, including double pulse testing (DPT), short-circuit testing, SOA, ruggedness, and device performance evaluation of SiC MOSFET devices.
• Design power electronics schematics and associated PCB layouts for reference designs and high-voltage semiconductor test hardware supporting device testing up to 10 kV, with appropriate isolation, creepage/clearance, protection, and measurement integrity.
• Define and optimize gate-drive solutions, including gate resistance selection, protection features, and isolation strategies.
• Design, build, and validate Evaluation (EVAL) boards for customer enablement and internal demonstration.
• Develop high-quality Application Notes, design guides, and technical documentation for customers and internal teams.
• Apply strong understanding of AI data center power architectures, including front-end AC/DC and back-end DC/DC stages and high-voltage DC distribution.
• Work with advanced power topologies such as totem-pole and interleaved PFC, LLC resonant converters, Dual Active Bridge (DAB), and solid-state transformer concepts.
• Perform current-sharing and transient simulations of SiC power modules, accounting for parasitic, gate-drive interactions, and layout-dependent effects using SIMetrix and PLECS.
• Perform device- and system-level simulations using PLECS.
• Conduct hands-on lab work using oscilloscopes, high-voltage probes, power analyzers, electronic loads, and other high-voltage test equipment.
• Develop and maintain LabVIEW-based automation for semiconductor characterization, validation, and data analysis.
• Provide technical enablement to FAEs and sales teams.
• Collaborate with R&D, product marketing, quality, and operations teams to support customer programs and product development.

Benefits
