Magnetics Engineer, Medium-Frequency Transformers
Core
Design medium-frequency transformers for solid-state transformers (SST) in gigawatt-scale AI data centers, focusing on core materials, winding structures, insulation, and liquid cooling.
Role type
Senior IC magnetics engineer (medium-frequency transformers)
Builds
Medium-voltage solid-state transformers and their power/cooling subsystems for gigawatt-scale data centers
Domain
Power electronics / Data center infrastructure / AI compute hardware
Required skills
High-frequency transformer/inductor design (kW-scale), medium-voltage magnetics insulation design, FEA for loss/inductance/hot spots, liquid cooling integration, prototype-to-volume production management, root cause analysis of test/field failures
Preferred skills
Nanocrystalline/ferrite core materials, epoxy/silicone potting, ANSYS Maxwell/COMSOL, LLC/DAB resonant converter leakage design, IEC 61558/UL 1446 standards
Responsibilities
Design medium-frequency transformers (hundreds of kW, tens of kHz, tens of kV DC insulation), select core/winding/insulation/cooling to optimize loss/size/cost, validate designs via hi-pot/partial-discharge/impulse/thermal-cycling tests, review vendor designs and sign off on insulation margins, qualify suppliers for volume production, trace failures to root cause in insulation/core/winding
Seniority
Senior, hands-on IC
