  • Job Description


    Cree/Wolfspeed is looking for an enthusiastic, self-motivated, and hands-on semiconductor test engineer who will be part of a team responsible for electrical characterization of power (MOSFET) and RF (GaN HEMT) on-wafer level testing in a volume manufacturing (clean room) environment.  Responsibilities will include designing, building, and qualifying electrical test systems, supporting various engineering activities required to keep production tools/test equipment running smoothly and providing daily production support as needed.  A successful candidate will be resourceful, works well with Engineering teams and Operations team, excellent problem solver with the capacity to quickly resolve a wide range of technical hardware and software challenges.


    Duties include:

    • Build, optimize, and sustain calibrated test stations which run in a 24/7 production environment
    • Maintain production test consumable items such as probe cards (including spares) and equipment spare parts to minimize tool down time
    • Generate and improve process and procedure documentations for production test systems
    • Perform on-wafer and bare-die level probing/testing
    • Work with Process Engineers and Product Engineers to design, execute, and analyze electrical and mechanical experiments to improve measurement, product quality and yield
    • Oversee training and certification of production personnel for production test systems
    • Develop and analyze daily and weekly process checks and scheduled preventative tasks for production test systems
    • Resolve and document various production issues during production testing when escalated by production technicians and/or equipment maintenance teams
    • Help with product disposition through test data review using provided data analysis tools/scripts


    • Candidate must be a US citizen or Green Card holder
