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.
