Senior Android Engineer

More than 75% of Talk360’s users are on Android. Every release you ship reaches hundreds of thousands of people across 190 countries, migrants calling home, travellers managing emergencies, families staying connected across borders. For these users, a dropped call or a crash isn’t a UX inconvenience. It’s a broken connection to someone who matters. 

The craft challenge here is real: our users are often on older devices, with limited data, in places where connectivity itself is unreliable. Making the app work beautifully in those conditions, fast, stable, trustworthy, is the work. And it never stops. 

We’re in a consequential moment. Talk360 has hit profitability, launched embedded calling with our first B2B2C partners, and is building toward becoming the world’s most trusted calling app. The Android platform sits at the centre of all of it. We’re looking for someone hungry to own that, who raises the bar without being asked to.
