Familiarity with ProtocolLib or comparable packet manipulation tools, the Bedrock Dedicated Server API, and proxy technologies such as Geyser or Floodgate is expected or strongly preferred.

Architect network features and integrations using packet manipulation libraries, and optimize server performance, memory use, and garbage collection for environments with high player counts. Develop Bedrock add-ons, behavior packs, and resource packs using the Minecraft Bedrock Scripting API, and work with C-based server interfaces or compatible proxy solutions where appropriate.

Build and maintain reliable cross-play features, ensuring a consistent user experience across console, mobile, and PC clients. Create and support player-data pipelines using relational databases or Redis. Help deploy, configure, and monitor server infrastructure with containerization, hosting platforms, or cloud services.
