I joined General Motors (GM) on March 5, 2018, starting with the two year TRACK program. The program allows you to rotate through 5-6 different positions, spending 4 months in each. I chose this program because I wanted to experience different roles within the different areas in engineering to figure out what I really liked to do before settling in to a permanent position.
GLOBAL B ARCHITECTURE EXECUTION (March 2018-June 2018)
This team’s goal is to support other software and embedded controls groups within the company with integrating a new architecture system.
My main tasks were testing in/out data identifier and receivers on the hardware in the loop (HIL) bench using software like Inca, ControlDesk, and other internal software. I also worked on setting up and executing over the air (OTA) testing on the HIL bench using internal software. My last project on the team was developing their internal website using HTML and CSS.
DRE FOR GLOBAL FRONT/REAR ELECTRIC AUTOMATIC TRANSMISSION HYDRAULIC CONTROLS HARDWARE (June 2018-October 2018)
This position, a Design Release Engineer (DRE), is similar to a project manager — I researched and worked with many different people inside and outside of GM to solve issues pertaining to my product. I interacted frequently with suppliers to collaborate on issue solutions. Using these resources, I successfully tracked and solved several issues from test failures and warranty returns.
I championed Engineering Work Orders (EWO) for design changes to improve valve/springs. I also led two continuous improvement projects regarding the paper gasket on one of the transmission valve bodies, and change valve spring shipping methods from pegged to bulk to save over $1M per year.
POWER INVERTER DESIGN (October 2018-March 2019)
My main project in this role was calibrating , validating, and identifying the thermal resistance for new technology inverter power modules. I successfully completed the project, measuring and calculating temperature resistance for four inverter power modules.
Another project I completed in this rotation was testing and identifying best methods to measure inductance in small inductive elements, like a bus bar. I completed my Design for Six Sigma (DFSS) green belt with this project.
L5P DURAMAX DIESEL CALIBRATION (March 2019-July 2019)
I was able to work directly with pre-production vehicles in this rotation. I completed over 50 Diagnostic Evaluations (DOE) for the NOx and O2 sensors on MY 2020 L5P Diesel trucks at the final step before production to verify that the system works correctly.
