Belgrade, Central Serbia Prepia Full time €40,000 - €80,000 per year

About Prepia

Prepia is one of the fastest-growing EdTech startups in the region.

Our goal is to become the go-to platform for exam preparation.

We recently raised €1.5M from top CEE VC fund Inovo and Silicon Gardens Capital, who supported creators of Talking Tom and Photomath. That means you're not joining an idea, but a funded product with real momentum.

We're aiming high, literally. Our office overlooks the entire city of Belgrade.

The Role

We're looking for a Senior React Native Developer who can take ownership of our mobile app experience end-to-end: build, ship, measure, improve, repeat.

This is a "ship something that affects real 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
    /
    .
  • 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 products to win with us long-term.
  • Hybrid work model:
    work from our Belgrade office Monday–Thursday, remote on Fridays.
  • FitPass.
  • Unlimited drinks, coffee, tea, etc.
  • Unlimited sweets/snacks in the office.
  • Team offsites and a genuinely friendly culture.
  • Conferences, courses, and advancement opportunities.
  • Fast-moving environment focused on real impact.

A Bit of Culture

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

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.
