A graduate of the Massachusetts Institute of Technology (MIT) with a Bachelor’s degree in Mechanical and Electrical Engineering, Jennie has built a career on driving data-informed strategies that dismantle the misconception of sustainability as costly and high-risk.

Previously, Jennie served as Product Creation Leader at Sonos, where she spearheaded the development of six hardware products, delivering $29 million in revenue 40% faster than projected timelines. She implemented novel operating models, improving gross margins by eight percentage points, and championed sustainability initiatives that informed design priorities using LCA results. Earlier in her tenure at Sonos, she successfully navigated global engineering responses to pandemic supply chain disruptions and optimized FCC regulatory filing strategies, achieving significant cost and time savings.
