• Leading the mechanical design and integration of the 2nd generation inverter assembly with aggressive timing/deliverables from the prototype concept phase through design/process validation (DV/PV), manufacturing qualification, and saleable production.• Managed multiple suppliers globally for high pressure die castings, plastic injection moldings, DC link capacitors, busbars, high-voltage headers, and low-voltage harnesses/connectors from early requirements quoting through overall design development and procurement for the inverter project. Reviewed and discussed supplier proposals to ensure components are optimally designed for manufacturability and assembly while balancing system-level needs and vehicle constraints.• Analyzed the compliance of assembly-level design metrics including tolerance stack analyses (fastener engagement, part-to-part interfaces, sealing design), busbar sizing based on current requirements, and electrical clearance/creepage conformance based on voltage ratings.• Developed laser welding process for high-voltage busbar interfaces as a suitable joining method. Performed extensive mechanical and electrical design trials against applicable industry standards to validate various laser parameters and busbar material considerations, along with internal quality metrics for verifying proper weld joints during assembly.• Developed heat staking process by assessing vendor capabilities and performing design trials on glass-filled plastic to ensure retention and stake quality adhere to system requirements.• Completed containment plans, root causes analyses, and corrective action definition/verification plans in JIRA for all mechanical build- and validation-related issues• Maintained the overall assembly 2D/3D CAD and Bill of Materials (BOM) in CATIA V6 3DExperience and released the assembly and components in Enovia to support on-time tool kick-off, part procurement, and vehicle program milestones.• ~Cost Savings Initiatives

• Performed analysis on traverse-based pressure ranges measured during LEAPX dual spool rig testing through Monte Carlo statistical simulations and made recommendations on pressure transducer ranges at each low pressure turbine stage to optimize efficiency and minimize uncertainty. Attended weekly meetings/discussions to communicate progress with data systems and turbine aero team and responded to questions and recommendations for other potential routes of analysis• Programmed MATLAB code to read in low speed research turbine hotfilm sensor data from non-standard format binary data to analyze airflow trends and created normalized contour plots to visualize wall shear stress along airfoil. Also created code to read in low speed research turbine hotwire sensor data to analyze the voltage readings and obtain air velocities.• Calibrated 5-hole pressure measuring probes by utilizing LabView programs to setup and control the different air speeds desired by the calibration jet as well as adjusting the probe pitch and yaw angles. Discussed troubleshooting of calibration of hotwire sensors where one of two sensors was not having the expected voltage readings after a certain angle of measurement.• Updated torque meter calibration sheets to account for additional serial numbers which represented 2000, 4000, and 7000 ft lb torque meters• Used MiniTab program's regression analysis to determine correlation between parasitic horsepower int he rig bearing and rotational speed and axial load• Converted key data validation files from interleaf to pdf format
