Powertrain - Dynamometer Test Engineer Technician 

My background started off in the transportation industry working with electric Light Rail Vehicles (LRV's) in the City Of Phoenix. I was able to learn many engineering aspects of high voltage systems as well as electrical and mechanical skills troubleshooting sub-systems in the trains. A year after I was giving the opportunity to join one of the most innovative companies in the transportation industry and until this day as my current job working with Tesla Motors. I started in the Powertrain team where I worked with manufacturing, sustaining, new product introduction (NPI), Design, software and hardware engineers from all levels. I took ownership of the quality aspect of NEMA 14-50 adapters, battery modules, motor inverters, and testing for durability and realibility of our current vehicle motors. 

Collaborated with a team of 5 senior engineers to design and build a powertrain dynamometer lab for Model S,
Model X, and Model 3 AC Motors within a three-month timespan. Assisted in the development of a standalone process for testing durability and reliability of Tesla powertrain subsystems including NVH, torque, voltage inputs/outputs, and speed commands. Analyze Noise Vibration Harshness (NVH) data and produce reports on the quality of individual motor components
to ensure that they meet quality specifications. Deconstruct tested motors to identify and evaluate the potential failures from manufacturing and new product introduction.

As part of the quality team I assisted in establishing PFMEA and control plans for various manufacturing lines and products. Investigated and prioritized field failures for various products and implemented root cause analysis and corrective action tracking. Enforced statistical process control on a newly introduced product which required extensive validation and GR&R (gauge repeatability and reproducibility). Improved existing battery design by developing prototypes and trials using new supplier parts within the battery manufacturing process

Powertrain - Product Excellence Engineer Technician 

Served as the technical advisor and key point of contact to 4 supervisors and 8 technicians to communicate new
modifications and ensure that electro-mechanical updates met City of Phoenix expectations. Performed firmware and software installation on a fleet of 50 sustainable urban Kinkisharyo light rail vehicles. Tested protocols and validated data acquisition on CAN/LAN/LON bus communication systems, monitoring logistics, GPS and CCTV surveillance systems for each light rail vehicle. Used troubleshooting tools such as digital multimeters, signal generators, amp meters, oscilloscopes, pneumatic tools, soldering irons, de-soldering stations, and schematics to perform printed circuit board level repairs.
