• Strong understanding of rotating machinery , insulation systems, over-temperature protection schemes, and high-voltage safety protocols.
• Familiarity with motor types such as BLDC, PMAC, and Infinitum’s proprietary PCB stator motors is highly desirable.
• Proficient with test equipment: oscilloscopes, power meters, DAQs, environmental chambers, and automated test platforms.
• Excellent verbal and written communication skills with experience working across cross-functional teams and external certifying bodies (UL, CSA, ETL).
• Highly organized with the ability to manage multiple concurrent certification efforts and project timelines.

Bonus Qualifications:

• Experience with DOE energy efficiency testing , IEC motor efficiency standards, or compliance programs like CE and CCC.
• Knowledge of embedded motor control systems or working within Agile development environments.
• Previous experience supporting internal lab certification or helping to establish a UL-compliant test facility.

What We Offer:

• Opportunity to shape the future of motor technology and sustainability.
• Collaborative work environment with a fast-paced, mission-driven team.
• Competitive salary, stock options, and comprehensive benefits.
• Access to cutting-edge tools and a high-tech test lab in Round Rock HQ.
