Full-Stack Software Engineer, Mobile Apps

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. 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.

ABOUT THE ROLE

You will own features end-to-end. That means holding a piece of work from contract through rollout across whichever surfaces it needs to touch, whether that's our TypeScript/Node backend, the iOS app, the Android app, or all three. Some features live mostly in the API layer. Some require real client work on one or both platforms. The job is to deliver the whole thing, not to hand off the parts that aren't your home surface.

This is a builder role. We want someone who likes shipping, can hold a feature from contract through rollout, works across stack boundaries without friction, and gets things in front of real users.

WHAT YOU'LL DO

In the first ninety days, expect to:

- Ship meaningful production code on one of our two products. We care less about scope than about you owning it end to end.

- Define and defend an API contract with mobile and design before writing the feature behind it, and iterate on that contract as you learn.
