Senior MBE Engineer


This job will consider folks coming out of academia.  If they have the PhD AND industry experience we could go a little higher. 

SUMMARY JOB OBJECTIVE, The Senior MBE Engineer is responsible for cost-effective process implementation and day-to-day engineering supervision of all assigned MBE reactors.  They will provide engineering support for the MBE process and are responsible for material quality in order to minimize wafer loss and ensure all delivered material meets or exceeds customer expectations.  This is accomplished through detailed analysis of internal metrology and customer test data.  The Senior MBE engineer is responsible for planning, directing and implementing the technical aspects of process improvement, research and development programs.
