Unity Mobile Game Developer – Contract (Remote)

We're looking for a contract Unity Developer to help maintain and grow our mobile learning games. Our flagship is a 3D vocabulary game built in Unity and live on both iOS and Android, part of a wider suite of vocabulary and reading products used by families and schools.

This is a hands-on development role centered on Unity and mobile. The game is a large, established codebase, so we need someone who has worked within a substantial Unity project before and can ship confidently to the App Store and Google Play. There is also backend and cloud work behind the game; the ability to contribute there is a strong advantage, but Unity and mobile development are the core of this role.

• →Develop and maintain features in our Unity (C#) game — gameplay, UI, Addressables, and the build pipeline
• →Manage iOS and Android releases, including SDK updates, provisioning, signing, and Swift Package Manager
• →Maintain third-party integrations such as Firebase, RevenueCat, AppsFlyer, and Apple/Google sign-in
• →Investigate and resolve bugs, most commonly around accounts, authentication, and activation
• →Support the backend and cloud services behind the game as features require

• Proven Unity/C# experience within a large, established codebase (not just prototypes)
• A track record of shipping mobile games or apps to the App Store and Google Play
• Confidence owning a feature from start to finish and debugging across the application
• Reliability and strong self-direction in a remote setting

• Backend development with Node.js or Python (REST APIs, JWT authentication)
• Subscription or in-app purchase integrations (RevenueCat or similar)
• AWS (S3, IAM, Redshift) or Firebase (Firestore, Cloud Functions)
• Social login (Google, Apple) and OAuth flows
• SQL for player and subscription analytics
• Experience with COPPA / KidSAFE or other children's-privacy compliance
• Transactional email systems

• Takes ownership of tasks and sees them through
• Manages a mix of quick fixes and longer feature work without dropping either
• Communicates clearly — raises issues early and proposes solutions
• Handles user data responsibly, with awareness that our audience includes children
