• Level Up Your Skills: Rapidly learn the Unity environment through dedicated mentorship from our senior game developers, transitioning your existing C# knowledge into world-class game engineering.

What We Are Looking For

• Around 5 years of experience in C# mastery: Strong professional experience writing maintainable code in C# / .NET frameworks.
• Solid CS Fundamentals: Deep understanding of object-oriented programming (OOP) & SOLID principles, data structures, algorithms, and design patterns.
• The Performance Mindset: Experience with profiling tools, diagnosing memory leaks, concurrency, and minimizing garbage collection overhead.
• Curiosity & Adaptability: A genuine interest in learning a new industry and the drive to adapt your technical skills to mobile applications and interactive media.
