AI Engineer

About Us

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.

  • You’ll then participate in a live, role-relevant working session as part of an interview loop with multiple interviewers. This experience is designed to reflect how work is done at Hiya and focuses on your real-time problem-solving and collaboration skills.

    During the session, you’ll work through a problem live and walk interviewers through your thinking as you go. Interviewers will explore how you structure problems, communicate your reasoning, respond to questions and feedback, and adapt your approach in the moment. .

  • Hiya Future Values Interview: An independent conversation focused on your long-term potential, judgment under ambiguity, and ability to create sustained value as scope and complexity increase.

• Reference Check: As a final step, we connect with 2–3 past supervisors to gain additional perspective on your experience and working style, and to further understand how you align with Hiya’s values.
