About Infinitum Electric:
At Infinitum Electric, we’re redefining electric motor technology from the ground up. Our innovative PCB stator design delivers industry-leading efficiency, reduced size and weight, and sustainable manufacturing—all while maintaining the performance and reliability our customers demand. We are growing rapidly and looking for dedicated professionals who want to be part of the next generation of smart, efficient, and eco-friendly motor systems.
 
Position Overview:
We are seeking an experienced and hands-on Electric Motor Test Engineer with a strong background in UL certification to join our high-performance engineering team. This role is critical in ensuring that Infinitum’s next-generation motors meet rigorous performance and safety standards while accelerating time-to-certification across our product portfolio. You will lead efforts related to UL 1004 series, UL 1446, and related motor and insulation system standards, serving as the technical interface between Infinitum and regulatory agencies.
 
Key Responsibilities:
•    Develop and execute motor testing protocols for performance, endurance, and safety—aligned with Infinitum’s unique PCB stator motor architecture.
•    Serve as the technical lead for UL certification efforts, managing test plans, documentation, lab coordination, and agency engagement from submission through listing.
•    Ensure compliance with UL 1004 series, UL 1446 (insulation systems), and other relevant motor safety standards.
•    Coordinate closely with product development, mechanical, electrical, and firmware teams to integrate compliance requirements early in the design cycle.
•    Prepare, review, and maintain detailed technical files, test data packages, and product risk assessments to support internal audits and third-party evaluations.
•    Operate and maintain test equipment including dynamometers, thermal chambers, power analyzers, and DAQs, ensuring high-quality data capture.
•    Lead root cause analysis and corrective action efforts when non-compliance or test failures occur.
•    Monitor changes in regulatory requirements (UL, CSA, IEC) and advise on implications for current and future motor designs.
•    Support internal lab certification programs and potentially help establish a UL DAP (Data Acceptance Program) capability at Infinitum.
 
Qualifications:
•    Bachelor’s degree in Electrical Engineering or a related field (Mechanical or Mechatronics with strong electrical emphasis also considered).
•    5+ years of experience in electric motor testing, validation, and compliance.
•    3+ years of direct experience with UL certification projects—ideally for motors, drives, or electromechanical assemblies.
•    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.
 
Join Infinitum Electric to help power a more efficient, connected, and sustainable world—one motor at a time.

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
