Omnicasa is a B2B CRM platform built specifically for the real estate industry. We're a small, tight team spread across Belgium, Vietnam, and Morocco — and we move fast. Our mobile app runs on Expo and is a core part of what we sell. It needs to feel like a native iOS/Android app, not a web app wrapped in a shell.

We've already done the hard work of migrating away from a legacy .NET MAUI app to a fully Expo-based stack. We use native UI components throughout, and the app reflects that. We take design seriously — liquid glass effects, native navigation patterns, platform-appropriate animations. If you look at our app and think "that's clearly React Native," something has gone wrong.

 

 

What you'll do

• Own and extend our Expo mobile app — new features, performance improvements, and platform-specific polish
• Work with native modules (Swift/Kotlin exposure is a plus, not a hard requirement)
• Collaborate with our design team to implement UI that genuinely looks and feels native on both iOS and Android
• Contribute to architecture decisions — we want someone who has opinions, not someone who just executes tickets
• Help maintain quality: you'll be the person who pushes back when something doesn't feel right on device

Your Skills and Experience

Must-haves:

• 4+ years working with Expo and React Native — not as a side project, as your primary stack
• You've shipped real apps to the App Store and Google Play, and you know what "production-ready" actually means
• Strong TypeScript fundamentals
• You understand the difference between Expo Go, development builds, and managed vs bare workflow — and when to use which
• Experience with Expo Router, EAS Build, and OTA updates
• You care about the details: gesture responsiveness, scroll physics, transition timing, platform conventions
• Experience with native UI paradigms (blur effects, vibrancy, Dynamic Island, haptics, etc.)

Strong plus:

• Expo DOM Components or brownfield integration experience
• Eye for design — you can look at a screen and know when something is off, even if you can't always explain why immediately
• Animation experience with Reanimated 3 and Gesture Handler

Not a fit if:

• Your React Native experience is mostly web-to-mobile ports that "kind of work on mobile too"
• You've only worked in Expo Go and never shipped a production build
• You think platform differences are an edge case
