## About the Role

* 3+ years building products and shopping code to production
 * Strong production mobile experience: you've built and shipped substantial features on iOS or Android, with deep expertise in at least one platform.
 * Willingness to work across the full scope: you want to contribute to iOS, Android, shared Kotlin Multiplatform code, and backend services as a regular part of your role.
 * Experience beyond your primary platform: you've made meaningful contributions to another mobile platform, shared mobile code, or backend services.
 * Solid backend and API sense: you can build the endpoints your app needs, not just consume them.
 * Ownership and initiative: you can unblock yourself by clarifying an ambiguous problem, proposing a solution, and carrying it through to production.
 * Good English: our team is international and English is our working language.

Nice-to haves:

 * Experience building backend services, especially in Go or Java.
 * Experience shipping a mobile app, having contributed to both iOS and Android.
 * Experience working with Kotlin Multiplatform.
 * Experience designing APIs and monitoring or troubleshooting features in production.

You'll thrive here if...

 * You think about the complete user journey and the systems behind it.
 * You enjoy developing expertise while learning from colleagues in other areas.
 * You can weigh code sharing against platform-specific needs.
 * You care about shipping useful features, maintaining code quality, and learning from what happens after release., We believe hiring is a two-way street. Here's what to expect:
 1. Recruiter pre-screen (20 min) - a first conversation to learn more about your experience and answer any initial questions
 2. Intro call with Zsolt (45 min) - get to know each other and answer your questions
 3. Design session (45 min) - discuss how you'd approach a real problem
 4. Coding session (60 min) - pair on a practical challenge, with no trick questions
 5. Team fit & HR (90 min) - meet the team and discuss logistics

Location: You must be based in France, hold a valid work permit, and be willing to relocate within 100 km of our Sophia Antipolis office.

## Description

* Own features end to end: work with Product and Design to shape solutions, build across mobile and backend, and follow through after release.
 * Build for both mobile platforms: contribute to our iOS and Android apps, creating experiences that feel right on each platform.
 * Develop our shared Kotlin Multiplatform layer: share logic where it brings value and make thoughtful decisions about what belongs in shared or platform-specific code.
 * Contribute to our backend: build and evolve the APIs and services your features need.
