Position: 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.

We are looking for a highly experienced Senior Game Developer / Lead Game Engineer who can help architect, develop, optimize, and scale this next-generation virtual world.

Key Responsibilities 1. Game Engine & Core Architecture
  • Lead development using Godot 4.
  • Design modular game architecture for a persistent virtual world.
  • Develop reusable systems for world management, rendering, physics, movement, interactions, and animation.
  • Build cross-platform systems supporting browsers, Android, iOS, Windows, macOS, and Linux.
  • Evaluate and integrate appropriate open-source technologies.
  • Create scalable foundations for future 3D expansion.
2. Open-World Development
  • Develop large, interconnected virtual cities and environments.
  • Implement terrain systems, buildings, interiors, roads, vegetation, and interactive objects.
  • Build procedural generation tools and automated environment pipelines.
  • Implement streaming, chunk loading, level of detail, and asset management.
  • Develop day/night cycles, weather effects, and environmental animations.
  • Optimize worlds for low-end devices and browsers.
3. Multiplayer & Networking
  • Implement real-time multiplayer systems.
  • Design client-side multiplayer synchronization.
  • Implement entity interpolation, prediction, reconciliation, and lag compensation.
  • Work with backend engineers on authoritative server architecture.
  • Support dynamic world instances, spatial partitioning, and interest management.
  • Develop multiplayer features for avatars, properties, objects, vehicles, and interactions.
  • Engineer reliable reconnection and state recovery.
4. Avatar, Character & Animation Systems
  • Develop customizable 2D, 2.5D, and 3D avatar systems.
  • Implement character controllers, skeletal animation, inverse kinematics, and animation blending.
  • Build facial expressions, gestures, emotes, and contextual interactions.
  • Integrate avatar customization, clothing, accessories, and appearance systems.
  • Support avatar optimization for multiple device classes.
5. Realistic Environment & Simulation
  • Implement lighting, shadows, weather, environmental effects, and physical interactions.
  • Develop vehicle movement, traffic simulations, and pedestrian navigation.
  • Implement NPC behavior, pathfinding, and navigation systems.
  • Create interactive homes, offices, shops, cafs, and public environments.
  • Integrate procedural and AI-assisted world creation.
6. Performance & Optimization
  • Optimize CPU, GPU, memory, draw calls, shaders, and rendering pipelines.
  • Develop graphics quality settings for low-end mobile devices and high-performance computers.
  • Implement texture compression, asset streaming, batching, and rendering optimization.
  • Profile and resolve performance bottlenecks.
  • Improve initial loading speed and runtime stability.
7. Tools & AI Integration
  • Develop internal tools for world creation and asset placement.
  • Integrate Blender and other 3D content creation pipelines.
  • Build reusable tools for designers and artists.
  • Collaborate with AI engineers to create natural-language-driven world-building workflows.
  • Implement AI-generated asset integration and automated validation.
8. Technical Leadership
  • Define coding standards and architectural guidelines.
  • Conduct code reviews and mentor junior developers.
  • Collaborate with 3D artists, UI/UX designers, backend engineers, Dev Ops engineers, and AI teams.
  • Own technical design documentation and development milestones.
  • Drive architecture decisions while balancing scalability, performance, and maintainability.
Mandatory Technical Skills
  • 7+ years of professional game development experience.
  • Strong hands-on experience with at least one production game engine, preferably Godot, Unity, or Unreal Engine.
