Spam, scams, and AI manipulation have eroded what was once a simple way to connect. Hiya is changing that. 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!

As voice threats evolve faster than ever; driven by AI-generated abuse, sophisticated spoofing, and increasingly complex attack patterns. You'll own the end-to-end pipeline that enables our data science team to develop increasingly sophisticated scam detection models while maintaining strict privacy and regulatory compliance. It's all about building the pipelines that allow Hiya to stay ahead of rapidly evolving voice threats and deliver measurably better protection to mobile operators and their subscribers worldwide. You'll shape how protection scales across our network, how quickly we adapt to new threats, and how effectively we translate AI innovation into real-world safety outcomes.
