Senior Android Engineer

The Challenge 

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. 

What You’ll Do 

• Own and evolve the Talk360 Android app, used by hundreds of thousands of people across 190 countries 

• Build and ship features that matter: embedded calling integrations, Auto Top-Up, payment improvements, authentication flows, call quality tooling 

• Ensure the app performs reliably on low-end devices and in limited-connectivity conditions, this is non-negotiable for our user base 

• Experiment with AI tooling to improve your own development speed and quality, we’re actively building an AI-first engineering culture 

• Investigate and resolve bugs using real-world reports and call quality monitoring data 

• Work directly from user research findings and Play Store feedback to inform what gets built and how 

• Contribute to sprint planning, architectural discussions, and technical decision-making 

The Team 

You’ll be working alongside Igor (iOS Mobile Lead) and Tom (Tech Lead), who together lead the mobile and engineering direction. The wider tech team you’ll collaborate with includes Michal & Feyi (QA), Alex (Backend), Isah (Frontend), Oleg (Full Stack), and Yahaya (VoIP). On the product side, you’ll work closely with Pedro and Kseniia. 

Talk360 is a lean company, around 30 people globally, which means you’ll interact regularly across functions: ops, support, data, and marketing. That cross-functional visibility is one of the things that makes the work here interesting and your impact visible.

About Talk360 

Talk360 has grown into a global communications platform connecting more than 6 million people worldwide. We successfully spun off our payments arm into NjiaPay, stepped into the gap left by the discontinuation of Skype, and achieved profitable growth from 2025 onwards, marking our transition from early-stage scale-up to a disciplined, sustainable business. 

We’re now expanding beyond our own B2C app. We’ve built and launched an SDK that lets partner platforms embed Talk360’s calling infrastructure directly into their own products, opening a new distribution channel and a new layer of technical complexity. Our ambition is bold: to become the world’s most trusted way to call any real phone number, connecting migrants, travellers, professionals, and businesses across the globe. 

Here’s what our users say:
