Senior Game Developer / Lead Game Engineer

OMRE Virtual World is an ambitious project to build a persistent, shared digital civilization where millions of people can live, communicate, work, own properties, operate businesses, explore cities, and participate in a functioning virtual society.

Unlike traditional games, OMRE Virtual World will be a continuously evolving environment with real-time multiplayer interactions, persistent identities, a virtual economy, transportation, realistic cities, dynamic weather, and AI-powered systems.

Our vision is to create an accessible virtual world that operates across web browsers, mobile devices, and desktop computers.
