  • Job Description

    Job Summary 

    This Systems Engineer within the Wolfspeed Power R&D team will play a key role in defining the next generation of high voltage (>600 V), high current (A to kA), Silicon Carbide (SiC) power semiconductor device technology building blocks and packaging technologies. They will use a multi-disciplinary approach to understand customer needs, develop concepts, design experiments, customize testbeds, and quantify key design tradeoff spaces. Results will be used to guide design approaches, highlight technology gaps, and justify/prioritize roadmap development thrust areas. 

     

    What can Wolfspeed do for you? 

    • Join a high-visibility R&D team working closely with all parts of the Wolfspeed Power business. 
    • Develop in-depth, hands-on experience with the latest high-voltage SiC power semiconductor die, discrete packaged parts, and multi-chip power modules. 
    • Engage with leading customers in the automotive, renewable energy, and industrial markets. 
    • Define and work on exciting projects across a range of important and challenging topics. 
    • Opportunity to guide the development of next-generation semiconductor device designs to bring new levels of performance, affordability, and usability to a wide-ranging marketplace. 

     

    What can you do for Wolfspeed? 

    • Interface with the Sales, Marketing, and Applications Engineering groups + key customers to clearly understand customer needs. 
    • Work closely with the Test, Characterization, Reliability, and Failure Analysis teams to maintain understanding of the present state of technology. 
    • Assess technology gaps and identify where R&D activity is needed to enable the business to offer systematic solutions meeting customer’s complete set of needs. 
    • Work with power semiconductor device design and fabrication process engineering to design exploratory simulations and experiments to prove concepts and quantify tradeoff spaces. 
    • Design testbeds to validate product performance, identify safe operating areas, and validate failure modes. Develop necessary metrology, datalogging, and post-processing tools facilitate clear understanding. 
    • Capture high-value intellectual property through invention disclosures and patent filings. 

     

    What you need for success: 

    • MS degree in Electrical Engineering with experience in one or more of the following fields: power electronic converter design, applications engineering, power semiconductor device characterization / test engineering, power packaging technology. 
    • Strong working knowledge in multiple physical domains: electrical, magnetic, thermal, and mechanical. Able to communicate effectively across domains in terms of interaction modes, failure modes, and best-known practices within the context of power electronic converters. 
    • Experience defining, scoping, and leading research projects to a tangible conclusion. 
    • Strong working knowledge of experimental design (DOE) and statistical data analysis using tools such as SAS JMP, Minitab, or similar. 
    • Experience supporting DFMEAs and DVP&Rs to identify, understand, and retire product risk. 
    • Comfortable exploring product performance limits and failure modes via simulation through destructive hardware testing at high voltages and high currents. [Translation: blowing stuff up to learn things.]
    • Experience with 8D problem solving methodology and root cause analysis techniques. 
    • Excellent verbal and written communication skills. Technical reporting at peer level and business management level. 
    • Comfortable to request support, justify priorities, and seek buy-in from the business unit. 
    • May be required to travel domestically or internationally up to 10%. 

      

    Highly preferred skills and certifications: 

    • PhD degree in Electrical Engineering plus relevant industry experience as a key contributor in a Power Electronics R&D team.
    • Experience designing or working with high voltage systems (hundreds of volts), operating at high currents (tens of amps to kiloamps), and high-power levels (kilowatts to megawatts).
    • Experience with variable frequency motor drives and automotive traction inverters is highly preferred.
    • Experience with grid-connected power electronic inverters.
    • Experience with JEDEC and AEC-Q101 power semiconductor qualification standards and test methods.
    • Experience performing multi-domain Finite Element Analysis studies using tools such as COMSOL or ANSYS multiphysics suites. Ability to correlate simulated results to measured physical data is highly preferred. 
    • Experience working with large datasets using programming and scripting tools such as MATLAB, Octave, JMP/JSL, Python, C++ or similar. 
    • Knowledge of best practices involved in high-speed power printed circuit board layout. 
    • Experience with invention disclosure and patent application processes.

    Overview

    At Cree | Wolfspeed, we’ve spent more than 30 years developing industry firsts as a leader in wide bandgap semiconductor technology. Not familiar with all of our products? That is because we are a part of the invisible revolution; if we do our job right you will never know we were there. Our products make impossible possible like our LEDs that power cities to our Silicon Carbide (SiC) and Gallium Nitride (GaN) components that power electric vehicles, solar energy, telecommunications and industrial, military and aerospace solutions.

     

    We believe in enabling the world to do more with less. That’s why we encourage each other to think unconventionally, take ownership and solve real problems. Interested in a career at Cree | Wolfspeed? We want to meet you. Submit your application now.
