About Joanne Diaz
With a diverse background spanning automotive, medical devices, and energy systems, I bring over 9 years of engineering and product leadership experience across Asia-Pacific and North America. Currently, I serve as a Product Manager at Yazaki Innovations, Inc, where I lead the development and go-to-market strategy of advanced busbar solutions for EV battery systems and power applications.My career began in R&D and design engineering, developing PTCA guidewires and stents for cardiovascular treatments. I later advanced through roles in quality control, HVAC component design, CAE simulation, and marketing strategy at DENSO, supporting multi-country operations and customer-centric innovation across the thermal systems business.I’ve designed and commercialized products using tools such as SolidWorks, CATIA, UG NX, ANSYS, STAR-CCM+, Power BI, and Aspen HYSYS, while also leveraging APQP, FMEA, and DRBFM for risk reduction and design quality.Backed by an MBA and engineering expertise, I thrive at the intersection of product innovation, market insight, and operational excellence—bridging technical and business functions to drive sustainable growth.Let’s connect if you’re interested in EV technology, advanced manufacturing, or global product strategy.
