Swift & Kotlin Developer - PT Freelance - Worldwide

Role Overview

Join our team to help develop an innovative, gamified language-learning app. We are looking for a skilled Swift (iOS) & Kotlin (Android) Developer to create an engaging, physics-based racing mini-game that will be a pivotal feature within our React Native app. Your work will directly support the app’s interactive learning experience by enabling real-time, skill-based gameplay.

Responsibilities

• Develop a modular, physics-based racing mini-game using Swift (iOS) and Kotlin (Android), designed to integrate cleanly into our existing React Native environment
• Write clean, well-documented, and scalable code to allow for future expansion and easier collaboration or handoff to future developers
• Collaborate with designers and other devs to ensure smooth integration and consistent visual experience across platforms
• Conduct thorough testing for performance, responsiveness, and low-latency gameplay across devices.

Required Skills

• Proficiency in Swift (iOS) and Kotlin (Android) for mobile game development
• Experience embedding or working alongside React Native apps (React Native knowledge is helpful but not required for game logic)
• Strong understanding of 2D physics principles as they apply to racing or side-scrolling games
• Ability to build modular, maintainable code that supports future scaling and feature additions

Nice to Have

• Experience with gamification mechanics or education-based games
• Familiarity with modular architecture and integrating native modules into hybrid apps
• System design experience (e.g., designing clean game modules or real-time multiplayer architecture)
• Strong communication and collaboration skills, especially when working with cross-functional teams
