Foundry Process Engineer Rf Gan Jobs (NOW HIRING)

The group seeks an engineer/scientist to conduct research and development to advance the state-of-the-art in ultra-wide bandgap semiconductor devices from first-of-a-kind demonstrations to prototypes suitable for technology transfers for applications relating to RF electronics (communications, radar), power electronics (radio frequency, power conversion, sensors, etc.), and other related electronics components for extreme environments. In this role, this individual will serve as a (1) technical subject-matter expert, (2) lead and execute technical projects, (3) contribute to technology roadmaps to establish future generations of the Laboratory's special-purpose device technologies. Duties will require familiarity and leadership in device design, understanding of epitaxial growth processes, fabrication (process development and integration), packaging, test, evaluation and analysis.  In addition to technical skills, the candidates should excel in multidisciplinary teamwork, clear and effective communication, independent problem-solving, and meeting program goals and project schedule deadlines.
