Senior Full-Stack Mobile Developer

About Us

Arpeely has been working deep in the web’s infrastructure while partnering with Fortune 50 companies. Over the years, we’ve built large-scale AI and real-time systems that handle billions of interactions daily. That experience gave us a front-row view of how the web really works: how people use it, where performance breaks, and where privacy and clarity often get lost.

Now we’re applying this knowledge to something new - a browser built from the ground up to make everyday online use simpler, more intuitive, and dare we say it - fun. This isn’t a side project or a concept; we’ve shipped a beta that’s growing by the hour and built on a foundation we know inside out.

We’re reimagining the browser to make the web feel lighter, clearer, and more personal, with AI woven naturally into the experience to enhance everyday browsing. From search to multitasking, everything is designed to feel natural, helpful, and even a little fun. The goal is simple: remove friction, surface what matters, and help people get things done online without feeling overwhelmed. It’s a product built for real users, not tech demos, and we’re scaling fast with a small, focused team that cares about UX and performance.

We’re hiring a Senior Full-Stack Mobile Developer to join the team and take a central role in building our mobile product. This role reflects what modern product engineering looks like: ownership across the stack, strong product judgment, and the ability to turn early ideas into polished experiences used by real customers.
