Unity Expert for Mobile Game Overhaul

Job ID: 40481434

Budget: $2 – $8 USD

Senior Unity Developer Needed – Mobile Game Backend Takeover, Multiplayer Improvements & Game Expansion

We are looking for an experienced and highly skilled Unity developer to take over and improve an already launched mobile game project available on both iOS and Android.

This is not a beginner project. We are looking for someone professional, reliable, and experienced with Unity multiplayer systems, backend architecture, mobile optimization, and polished game development.

Project Status

The mobile game is already live and published on:

Apple App Store (iOS)

Google Play Store (Android)

The game currently exists and is functional, however we are facing major backend and infrastructure issues that now require immediate restructuring and professional handling.

The game is a 2D board game platform containing multiple different game modes/games within the application. Some game assets and tokens are designed as 3D tokens/elements integrated into the 2D gameplay environment.

Main Priority – Backend Takeover & Infrastructure Migration

The most urgent requirement is:

Replacing and restructuring the current backend system

Migrating the game infrastructure to our own backend and server environment

Full backend ownership and control under our infrastructure

Improving backend stability, scalability, and multiplayer reliability

Ensuring secure architecture and long-term maintainability

This is the highest priority phase of the project.

Game Improvement & Polishing

In addition to backend restructuring, we also want improvements across the game itself:

Required Improvements

Improve gameplay polish and overall user experience

Improve and refine game animations

Improve multiplayer connectivity and synchronization

Optimize performance and stability

Improve networking reliability and responsiveness

Fix existing issues where needed

We are looking for polished, professional execution — not quick temporary fixes.

Future Development

The project also includes planned future expansion:

Three additional game modes/features planned for release

These future components will also require development and integration into the existing game ecosystem

This may become a long-term collaboration for the right developer.

Requirements

Strong professional Unity experience

Experience with multiplayer/mobile games

Experience with 2D game systems and mixed 2D/3D elements

Strong backend and server integration experience

Experience with infrastructure migration and backend restructuring

Experience with game optimization and networking

Experience publishing/updating games on App Store & Google Play

Ability to work with existing codebases and improve them professionally

Important Notes

This is an existing live product, not a project built from scratch

We are looking for a serious technical partner

Clean architecture and scalable solutions are important

This is a budget-conscious project with defined priorities and scope

To Apply

Please include:

Relevant Unity/mobile game projects

Multiplayer/backend experience

Experience with infrastructure/server migration

Estimated timeline and cost

Your approach for backend takeover and multiplayer improvements

Thank you.
