You'll contribute to the product from its early development stages, taking ownership of mobile architecture, technical decisions, and application quality, with particular emphasis on the iOS ecosystem, performance, and user experience.

• Integrate authentication, authorization, and security mechanisms to protect users and their information.
• Work with iOS-specific capabilities, native modules, device permissions, and platform integrations.
• Integrate REST APIs, payment gateways, geolocation services, and push notifications.
• Collaborate with backend engineers to support real-time availability and reservation management.
• Optimize application performance, stability, and user experience, particularly on iOS devices.
• Contribute to mobile architecture, testing, code reviews, and engineering best practices.
• Manage iOS builds, signing, provisioning profiles, TestFlight testing, and App Store releases.

What You Bring

• 8+ years of software development experience, including 5+ years working with React Native.
• Advanced proficiency in React Native, TypeScript, and JavaScript.
• Strong hands-on experience building, deploying, and maintaining production-ready iOS applications.
• Solid understanding of the iOS ecosystem, Xcode, CocoaPods, app signing, provisioning, and App Store deployment.
• Experience with React Native architecture, navigation, reusable components, and state management solutions such as Redux Toolkit or Zustand.
• Strong knowledge of REST API integrations, authentication, and secure session management.
• Experience integrating native iOS capabilities, third-party SDKs, push notifications, and geolocation services.
• Knowledge of mobile performance optimization, debugging, and automated testing.
• Familiarity with Git, CI/CD pipelines, and mobile application release processes.
• Ability to work independently, make technical decisions, and contribute to product architecture.
• Strong communication skills and a product-oriented mindset.

Nice to Have

• Native iOS development experience using Swift or SwiftUI.
• Experience with booking platforms, marketplaces, or SportsTech applications.
• Knowledge of digital access control, QR-based check-in, NFC, or identity verification.
• Experience with Apple-specific capabilities such as Apple Wallet, Sign in with Apple, or Core Location.
• Experience integrating payment solutions such as Stripe or Apple Pay.
• Familiarity with Firebase, Expo, or EAS.
• Experience with real-time applications using WebSockets.
• Experience using AI-assisted development tools such as Cursor, GitHub Copilot, or Claude Code.
