Power Electronics Engineer
FluidStack — Austin, Texas, United States · In-Person · Mid
Role description
Role Overview
The Power Electronics Engineer will design and develop high-power or medium-voltage power converters, solid-state transformers, and other power electronics systems for Fluidstack's AI data centers. The team is focused on delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. The engineer will work on key problems such as architecting a medium-voltage solid-state transformer, defining the interface between the SST and the MVDC distribution system, and building a semiconductor and magnetics supply strategy.
What You Will Do
Design the SST cell and block in detail, simulate, build, and bring up the first cell prototypes, turn the program's architecture decisions into a buildable design, test vendor hardware and data against your own models, and carry the design through cell, block, and pilot-unit design reviews.
Why It Might Be a Fit
We're looking for exceptional people who care deeply about the problem space and have hands-on experience developing and validating high-power or medium-voltage power converters, isolated DC-DC converters, and conversion systems from initial simulation models through hardware bring-up and full qualification testing.
Requirements
- hands-on experience developing and validating high-power or medium-voltage power converters
- experience with isolated DC-DC converters utilizing 1.7 kV+ SiC devices
- experience guiding conversion systems from initial simulation models through hardware bring-up and full qualification testing
- experience collaborating across PCB, controls, and magnetics domains to balance architectural trade-offs
- experience identifying hardware bugs during bench evaluation and resolving them in subsequent board iterations
