Medior Backend Engineer, Enterprise Success

At Hiya, we’re making business calls more trusted, useful, and effective.

Voice remains one of the most important ways businesses communicate with their customers, but the value of a call depends on trust. When customers do not recognize who is calling or why, important conversations are missed, customer relationships suffer, and business outcomes are harder to achieve.

Hiya helps businesses create trusted calling experiences that benefit both sides of the conversation: enterprises can reach customers with confidence, and customers can answer with confidence. Our products support branded business calling, trusted caller identity, call performance insights, customer engagement, and voice security capabilities that help businesses strengthen relationships and improve outcomes.

This role sits in a core business area for Hiya and is focused on helping SMB and enterprise customers succeed.

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. 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. You won't just work on what voice is today, you'll shape what it becomes tomorrow: smarter, safer, and genuinely worth answering again.
