Senior Full-Stack Mobile Developer

Description

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.

What You’ll Do

• Take full responsibility for features end-to-end, from technical design through implementation, testing, release, and production monitoring.
• Design, build, and ship our mobile application using React Native and TypeScript.
• Develop and maintain backend services and APIs, primarily in Python.
• Work across the client, backend, databases, analytics, and supporting infrastructure.
• Collaborate closely with product and design to turn early ideas into fast, intuitive, and polished user experiences.
• Analyze product and production data to understand performance, identify opportunities, and guide improvements.
• Make pragmatic technical decisions that balance development speed, quality, and maintainability.
• Improve our testing, deployment, observability, and release processes.

Requirements

• 5+ years of hands-on software development, with a proven track record of shipping production applications used by real users.
• Strong full-stack experience: you've built both modern client apps (web or mobile, e.g., React, TypeScript) and the backend services behind them, not just contributed to one side.
• Strong backend experience in a modern language (e.g., Python, Node.js, Go). Our backend is Python, and we'll help you switch.
• Solid understanding of databases, API design, system architecture, and cloud environments.
• Experience with automated testing and CI/CD.
• You build with AI coding tools (e.g., Cursor, Claude Code) every day and use them to ship significantly faster.
• Strong product sense and attention to UX, performance, and quality, ideally in B2C products at scale.
• You've owned and shipped a product or major feature end-to-end, from design to production, and can point to real impact.
• B.Sc. in Computer Science or equivalent experience.

Advantages

• React Native or native iOS/Android experience.
• Python backend experience.
• Experience taking an early-stage product from concept to production.
