- Optimize performance and debugging across platforms (mobile, web, AR)
- Support deployment pipelines and version control workflows (Git, CI/CD)
Requirements
- 3+ years of experience in Full Stack or Game Development
- Strong proficiency in Unity (C#) and C++ (for performance modules or plugin development)
- Understanding of client-server architecture, RESTful APIs, and cloud services (Firebase, AWS, etc.)
- Experience with real-time multiplayer or physics-based games a strong plus
- Familiar with version control (Git), task management tools, and agile workflows
- Ability to work independently, iterate fast, and deliver clean, maintainable code
- English required; Russian language a strong advantage (internal comms)
Nice to Have
- Experience with mobile optimization (iOS/Android)
- Knowledge of AR/VR frameworks
- Basic understanding of monetization systems and leaderboards
- Experience integrating analytics, user accounts, or cloud saves
