Job Overview
Based out of our Garden Grove headquarters, the Senior Powertrain Test Engineer is responsible for execution of system level Powertrain testing as part of Harbinger’s development and validation process. They will collaborate closely with fellow test engineers to execute comprehensive system-level testing, drive innovation in our test facility capabilities, and partner with stakeholders to develop robust testing methodologies. The role will have a key focus on the electrical, mechanical, and software integration of Powertrain systems and test rigs, building out robust instrumentation and data acquisition systems, and development of automated test software focusing on repeatability, efficiency, and safety.
What You’ll Do:
- Lead and execute component and system-level development and validation testing of electric motors and drive units within the lab.
- Maximize testing efficiency and data integrity through application of advanced methodologies, software development, and test automation.
- Design and construct electrical control panels (including power distribution, grounding, fuses, relays, terminal blocks, and safety interlocks) for automated test systems.
- Develop and maintain automated test software using LabVIEW or other text based programming environments for control of test hardware (e.g., DAQs, power supplies, relays, sensors).
- Leverage data analysis and advanced testing methodologies to reproduce and characterize failures for rapid issue resolution.
- Design and architect electric motor and drive unit dynamometers and HIL systems for development testing of advanced concept projects.
- Document system designs, schematics, software logic, and test procedures for compliance and knowledge transfer.
Who You Are:
- Bachelor of Science in Electrical Engineering (or similar) with a minimum of 7 years of relevant industry experience with emphasis on validation testing and system integration (mechanical, electrical, and software).
- Demonstrated experience in working with NI hardware (PXIe-RT, cRIO, and cDAQ) and coding with real-time and FPGA modules.
