• Define test parameters and methodologies including accelerated life testing (ALT), highly accelerated life testing (HALT), and highly accelerated stress screening (HASS).
• Use reliability modeling and statistical techniques (e.g., Weibull analysis, MTBF calculations) to assess product performance over time.
• Assist in building test setups and fixtures for mechanical, electrical, and thermal testing.
• Conduct stress, thermal, fatigue, and failure testing per component lifetime requirements.
• Analyze and translate testing data into reliability metrics and lifetime assessments.
• Create wiring diagrams and instrumentation lists.
• Write test automation code, via LabView, Ignition, Python or similar
• Integrate and calibrate various process sensors (temperature, heat flux, power measurement, etc.) to support accurate and reliable testing of thermal systems.
• Prioritize safety by implementing and adhering to safety protocols and industry standards throughout testing processes.
• Analyze test data for accuracy and consistency.
• Summarize test results and report out cross functionally.

What You Will Bring:

• Bachelor’s or Master’s degree in Mechanical/Electrical Engineering, Mechatronics, Thermal Engineering, or a related field.

• Good laboratory practices (GLP) with operating and handling materials involving electromechanical and high temperature applications.
• Familiar with HALT, reliability testing
• Good understanding of heat transfer principles and thermal systems testing methodologies.
• Strong analytical and problem-solving skills, with attention to detail in testing and validation.

Bonus Points!

• Experience with high-temperature materials testing (above 1000˚C).
• Knowledge of medium voltage systems and components.
• Background in PV solar system testing or integration.

What We Offer:

• Comprehensive Medical Benefits
• Dental & Vision Benefits
• Life Insurance and ADD
• Up to 13 paid holidays per year, in addition to a company week-long holiday in December
• Flexible time off policy
