The Role

We’re looking for a Senior React Native Developer who can take ownership of our mobile app experience, from end-to-end: building, shipping, measuring, improving, and repeating. This is a “ship something that affects users this week" type of role. You’ll work with the development team to ship features used by thousands of learners preparing for high-stakes exams.

What You’ll Do

• Build new features in React Native (Expo) using TypeScript.
• Ship to production on both iOS and Android and handle updates through App Store / Google Play Console.
• Own in-app monetization, analytics, and attribution setup using tools like RevenueCat, PostHog, Appsflyer, Meta SDKs, etc.
• Improve performance, stability, and user experience of the mobile app.
• Collaborate with product and growth teams to move real metrics, not just close tickets.
• Debug, instrument, and iterate fast in a live environment with real users and real revenue.

Must-Have Experience

• Strong hands-on experience with React Native (Expo) and TypeScript.
• You’ve shipped and maintained real mobile apps (published apps in the App Store / Play Console).
• Working with subscriptions / in-app purchases (RevenueCat or similar).
• Analytics & event tracking (PostHog or similar).
• Mobile SDK integrations (Appsflyer, Meta, etc.).
• Comfortable owning features from idea to shipped build.

Nice to Have

• Backend experience with Node.js / Nest.js.
• DevOps exposure (Docker, CI/CD pipelines).
• Solid understanding of databases and data modeling.
• Growth mindset: interest in activation, retention, monetization.

What You Get

• Competitive salary + performance-based bonuses.
• Equity potential for key players. We want people who build core product to win with us long-term.
• Hybrid work model: work from our Belgrade office Monday–Thursday, remote on Fridays.
• FitPass.
• Unlimited drinks, coffee, tea, rakija, etc.
• Unlimited sweets/snacks in the office.
• Team offsites and a genuinely friendly culture. 
• Conferences, courses, and advancement opportunities. If you grow, we grow.
• Fast-moving environment focused on real impact.

A Bit of Culture

We care about output. We measure what we ship and how it performs.

If you like moving fast, having ownership, and seeing your work live in production constantly, you’ll fit in here.

Note: Only shortlisted candidates will be contacted.
