ABOUT HIYA At Hiya, we're making calls safe, useful, and human again. Voice is the most human form of communication, yet it's become one of the least trusted. Spam, scams, and AI manipulation have eroded what was once a simple way to connect. Each month our AI voice technology analyzes 28+ billion calls, protecting over 550 million users and 800+ businesses worldwide. Partnering with a growing global network including, AT&T, Samsung, British Telecom EE, Rogers, MasOrange, Bell Canada, MasMovil, and Virgin Media O2, we're not just stopping bad actors, we're helping people feel good and confident about picking up the phone again. This is a pivotal moment for voice. As new threats and technologies accelerate, so does demand for trusted voice communication. Hiya is growing 40%+ year over year, expanding globally, and defining what voice becomes next. Join us. You won't just work on what voice is today, you'll shape what it becomes tomorrow: smarter, safer, and genuinely worth answering again. ABOUT THE ROLE We're hiring a Sr. GTM Engineer, Marketing to transform Hiya's website into an AI-powered, revenue-driving digital growth engine. This role sits at the intersection of marketing, engineering, and product—responsible for leading our migration from Webflow to a headless CMS architecture while partnering closely with Marketing leadership to bring positioning, campaigns, and GTM initiatives to life through high-performing digital experiences. You will own website KPIs including traffic growth, engagement, conversion rate, and pipeline contribution, while architecting systems that enable rapid experimentation and global expansion. This is a high-ownership role with direct impact on how Hiya reaches customers, communicates value, and scales globally—making it central to our ability to restore trust in voice at scale and deliver on the promise of safer, more useful phone calls. We're looking for a marketing-minded engineer or technical marketer—someone who understands buyer psychology and funnel performance as deeply as frontend architecture, and who sees AI as a structural capability for reimagining how digital experiences are built, personalized, and scaled. As AI continues to reshape how calls are placed, screened, and answered, our digital presence must evolve with the same level of intelligence and adaptability we bring to the voice channel itself.
