Informacje o stanowisku

About the Role:

We are looking for an experienced Mobile Developer (Mid+ or Senior level) with at least 4 years of commercial experience in building mobile applications for Android and/or iOS.

The ideal candidate is a mobile-first specialist—we are looking for someone whose expertise is rooted deeply in the mobile ecosystem rather than web development. You should have a strong command of React Native and a passion for creating high-performance, user-centric mobile experiences.

The Project:

You will join a project for a major international corporation in the energy and chemical sector. We are developing a modern mobile application for B2B and B2C users that manages fuel cards, loyalty programs, and exclusive discounts.

The app has a real-world impact on the daily lives of drivers, supporting them on the road and through charging infrastructure. Key features include:

  • User Management: Smooth B2B and B2C registration and login.
  • Benefits: Fuel card management, loyalty rewards, and discount tracking.
  • Maps & Geolocation: Searching for stations and points of interest.
  • E-Mobility: Starting/stopping EV charging sessions directly from the app with real-time (live) status tracking.
  • Advanced Features: CarPlay integration (MVP) and dynamic widgets for quick access to key information.

  • 4+ years of commercial experience in mobile development (Android and/or iOS).
  • Expert-level knowledge of React Native.
  • A "mobile-first" mindset with experience in building complex mobile applications.
  • Deep understanding of the mobile ecosystem (build processes, testing, and store publication).
  • Strong proficiency in JavaScript and TypeScript.
  • Experience integrating with APIs (REST / GraphQL).
  • Strong problem-solving skills and the ability to work effectively both independently and in a team.

Nice to Have

  • Experience with native development: Kotlin/Java (Android) or Swift (iOS).
  • Hands-on experience with native deployment (Google Play Store / App Store, certificates, provisioning, signing).
  • Knowledge of CI/CD pipelines tailored for mobile apps.
  • Experience in mobile performance optimization.
  • Background in designing mobile application architecture.
