What you'll do: ? Server Architecture and Design: Design and implement robust and scalable backend systems for multiplayer games using C#. Ensure high availability, low-latency, and secure connections for players. ? Multiplayer Game Logic: Implement core multiplayer systems, including player matchmaking, lobbies, leaderboards, in-game transactions, and game state synchronization. ? API and Networking: Develop and maintain RESTful APIs and real-time networking protocols (e.g., WebSockets, UDP, etc.) to handle communication between the client (Unity) and backend servers. ? Data Management: Implement and maintain backend systems for player data storage, persistence, and retrieval. Ensure proper database management for player accounts, statistics, and game progression (SQL/NoSQL databases). ? Collaboration: Work closely with Unity developers to integrate backend features with the frontend game client. Provide support for debugging and troubleshooting multiplayer-related issues. ? Testing & Debugging: Conduct thorough testing of multiplayer systems, including load testing, stress testing, and debugging complex multiplayer interactions. ? Documentation: Maintain clear and comprehensive technical documentation for server code, systems, and APIs. What you'll need: ? Experience: 3 years of professional experience in backend development, preferably with a focus on multiplayer games. ? Proficiency in C#: Solid experience with C# for backend development, including familiarity with .NET Core, ASP.NET, or Unity backend solutions. ? Multiplayer Networking: Strong knowledge of networking protocols and concepts used in multiplayer games (e.g., client-server architecture, real-time synchronization, latency compensation). ? Database Management: Experience with relational and NoSQL databases (e.g., SQL Server, MongoDB, Redis) and understanding of database design and optimization. ? Game Development Experience: Familiarity with Unity and game development principles, including how game clients communicate with backend servers. ? Version Control: Proficient with version control systems such as Git and branching strategies. ? Problem Solving: Strong troubleshooting and debugging skills, with an ability to identify
