Controls Engineer

POSITION SUMMARY

Control Systems Engineer Engineering

Engineering Manager

The Controls Engineer as part of a greater cross-functional team within the Design Engineering group will design, debug, characterize, release to production, and provide product support of rectifiers, converters, and inverters for industrial power conversion equipment while meeting electrical design requirements. State-of-the-art power conversion equipment ranges in power from 3.5 kVA up to 250 kVA. This position is responsible for analyzing and modeling power electronic circuits such as rectifiers, converters, and inverters; and then developing and optimizing closed loop control algorithms and software in C programming language. This position also involves extensive laboratory work collecting and analyzing data on power electronic hardware to verify and improve the control functions.
