Emily Shenfield is a Principal Technical Product Marketing Manager at Twilio, where she sits at the intersection of engineering and marketing — translating complex technical capabilities into strategies that resonate with developer audiences. With over six years at Twilio, Emily has held roles spanning developer education, technical marketing, and hands-on demo engineering, giving her a rare end-to-end view of how developers actually discover, evaluate, and adopt developer tools. Before Twilio, she spent nearly five years as a software engineer at Lever, where she built product from the inside out. That combination — engineering credibility and marketing execution — is what makes Emily's perspective on developer program strategy genuinely distinctive.
