Mobile Developer

Onside is building the first alternative iOS app marketplace in the EU — a platform where developers can publish, distribute, and monetize their apps outside the App Store. We’re here to give developers more freedom, better monetization tools, and transparent policies. Think less bureaucracy, more creativity — and a team that actually ships.

Now we are looking for an experienced Mobile developer to join our team!

What you’ll be doing:

• Build and launch consumer-facing mobile applications for iOS and Android;
• Develop and maintain cross-platform mobile applications using React Native;
• Work closely with Product, Design, and Backend teams to deliver high-quality mobile experiences;
• Integrate mobile applications with backend services and APIs;
• Implement mobile UI/UX according to product requirements and design systems;
• Optimize application performance, reliability, and user experience across devices;
• Participate in app releases, updates, monitoring, and continuous improvements;
• Ensure application quality through testing, debugging, and code reviews.

Tech we use:

• React Native
• TypeScript
• REST APIs
• Git
• CI/CD
• Mobile analytics and crash reporting tools
• iOS / Android platform tooling

Why you’ll like it here:

• You’ll build something new and meaningful.
• Small, senior team with real ownership and no corporate layers.
• Fully remote, flexible hours, straightforward communication.
• We move fast and value people who do the same.

If you are passionate about technology and want to be part of a team that is redefining the marketplace experience, we would love to hear from you!
