• Develop and maintain native iOS applications using Swift
• Design and implement scalable, maintainable application architectures
• Build and maintain REST API integrations, including proper error handling and network communication
• Implement efficient data synchronization mechanisms between local storage and backend services
• Work with local persistence, caching strategies, and offline-first application concepts
• Apply modern Swift concurrency mechanisms to ensure safe and efficient asynchronous operations
• Analyse complex technical issues, troubleshoot application behaviour, and improve performance
• Participate in technical discussions and contribute to architectural decisions
• Collaborate with cross-functional Agile teams

• Experience with asynchronous programming and Swift Concurrency (async/await, Actors)
• Experience with local data persistence, caching, and data synchronization
• Understanding of offline-first application design and handling network connectivity issues
• Ability to independently analyse technical requirements and propose appropriate implementation approaches
• Good problem-solving skills and understanding of algorithmic complexity and edge cases
• Good English and Polish communication skills

NICE TO HAVE

• Experience with Core Data, SwiftData, SQLite, or similar local persistence technologies
• Experience with push notifications, including silent push notifications
• Knowledge of synchronization strategies, incremental data fetching, and conflict handling
• Experience with performance optimization and efficient network communication
• Experience developing enterprise-scale or travel-related mobile applications
• Knowledge of modern iOS architectural patterns such as MVVM, Clean Architecture, or VIPER
