Power Electronics Reliability Engineer

Job Title: Power Electronics Reliability Engineer

Location: Franksville WI

Duration: Long Term

Client: Unico

Job Description

• The Client is looking for a Power Electronics Reliability Engineer with hands-on experience performing DFMEA and MTBF analysis on power electronics products. This is much more of a reliability-focused role than a traditional validation or test engineering position. 5+ years of experience. Needs demonstrated power electronics experience not HIL or software test.

Key Requirements

• Experience leading or performing DFMEA (Design Failure Mode & Effects Analysis) on power electronics products.
• Experience developing MTBF/MTTF reliability calculations and models.
• Ability to review power electronics designs and identify potential failure modes and downstream impacts.
• Strong understanding of power electronic components including:
• Silicon carbide (SiC) MOSFETs
• IGBTs
• Capacitors
• Resistors
• Gate drive circuits
• Ability to analyze what happens when components fail (shorts, opens, over-current, over-voltage, thermal events, noise susceptibility, etc.).
• Comfortable reviewing schematics, component datasheets, and stress/derating conditions to identify reliability risks before product release.

Examples Of The Type Of Experience Needed

• Determining what happens if a SiC MOSFET or IGBT shorts and understanding the impact on downstream components.
• Identifying scenarios where excessive current through a resistor could create a thermal or fire risk.
• Evaluating capacitor voltage stress, electrical noise susceptibility, and other reliability concerns.
• Using DFMEA findings to drive design improvements and validation testing.

Additional Experience Desired

• Power conversion products such as drives, inverters, DC/DC converters, motor controls, or similar power electronics systems.
• Reliability testing, validation, root cause analysis, and field failure investigations.
• Experience with standards-based reliability methods (MIL-HDBK-217, Telcordia, Physics-of-Failure, etc.).
• Target Candidate: Someone who has spent years performing DFMEA and MTBF analysis on power electronics hardware and can quickly identify failure mechanisms, component stress issues, and reliability risks within a design.
