Senior Unity Developer for Game Enhancement
Budget: $2 – $8 USD
Senior Unity Developer Needed – Backend Takeover, Infrastructure Migration, Multiplayer Improvements & Long-Term Collaboration
We are looking for an experienced Senior Unity Developer (or a small experienced team) to take over and further develop an existing mobile game that is already live on both iOS and Android.
This is not a project built from scratch. The game is already published, has an existing player base, and requires an experienced developer who can work with an existing codebase, improve its infrastructure, and help us grow the product long-term.
About the Game
The game is a 2D multiplayer board game platform featuring multiple game modes within a single application.
As part of our future roadmap, we also plan to implement high-quality 3D game tokens and selected 3D visual elements to enhance the overall presentation while keeping the gameplay primarily 2D.
Three additional game modes are also planned for future development.
⸻
Phase 1 – Urgent Backend Takeover (Highest Priority)
This is the most urgent part of the project.
The current infrastructure is built around:
* Unity
* GitHub
* DigitalOcean
* Firebase
* Docker
We currently have access to:
* Unity project
* DigitalOcean
* Firebase
* Website
However, we no longer have access to the existing GitHub repository or the Docker environment. Therefore, the first objective is to migrate everything so the entire infrastructure is fully owned and controlled by us.
The work includes:
* Create a new GitHub repository under our GitHub organization/account.
* Migrate the existing project.
* Configure deployment using our DigitalOcean environment.
* Connect the project to our Firebase project.
* Create and configure a new Docker environment that we fully own.
* Update API keys and environment configuration where necessary.
* Restore backend functionality.
* Ensure the login system works correctly.
* Verify that the application is stable after migration.
This is an infrastructure takeover—not a complete rewrite of the project.
We expect this phase to be completed efficiently by someone experienced with Unity backend infrastructure.
⸻
Phase 2 – Multiplayer & Game Improvements
Once the backend has been stabilized, we want to improve the game itself.
Areas include:
* Improve multiplayer stability.
* Improve networking and synchronization.
* Improve responsiveness and matchmaking.
* Optimize performance.
* Improve gameplay polish.
* Improve animations and visual quality.
* Fix existing bugs.
* Improve scalability for future growth.
We are looking for professional, long-term solutions rather than temporary fixes.
⸻
Phase 3 – Professional Admin Panel
We also want a modern web-based admin panel that allows us to manage the game without requiring code changes for everyday administrative tasks.
The admin panel should include features such as:
* User management.
* Grant player rewards, winnings, currency, and compensation.
* Create and manage tournaments.
* Manage events and promotions.
* Configure game settings.
* Manage future game content.
* View player statistics and analytics.
* Monitor backend/server health.
* Administrative moderation tools.
* Secure role-based access control.
* A scalable structure that supports future expansion.
The objective is to make future operations significantly easier and reduce manual backend work.
⸻
Future Development
This project has long-term potential.
After the initial migration and improvements, we plan to develop three additional game modes and continue expanding the platform.
We hope to establish a long-term relationship with the right developer.
⸻
Requirements
You should have proven experience with:
* Senior Unity development.
* Mobile game development.
* Multiplayer systems.
* Backend architecture.
* Firebase.
* DigitalOcean or similar cloud infrastructure.
* Docker.
* Infrastructure migration.
* Networking.
* Performance optimization.
* Working on existing live games.
* Publishing and maintaining games on both the App Store and Google Play.
⸻
Important
This is a live production project. We are looking for a professional developer who writes clean, scalable, and maintainable code.
Hourly Rate Policy
Please do not apply if you intend to increase your hourly rate after being hired.
We are not interested in developers who submit an artificially low bid to win the project and then request a significantly higher rate later.
If you apply, your proposed hourly rate should be the rate you are prepared to work at throughout the engagement. We respect professional pricing and are happy to pay fairly for quality work, but we expect complete transparency from the beginning.
⸻
To Apply
Please include:
* Examples of relevant Unity projects.
* Multiplayer experience.
* Backend and infrastructure experience.
* Experience migrating live production systems.
* Experience with Firebase, DigitalOcean, and Docker.
* Your proposed approach to the backend takeover.
* Your approach to improving multiplayer.
* Estimated timeline for Phase 1.
* Your hourly rate.
* Why you believe you’re the right fit for this project.
We are looking for a long-term technical partner who can help us stabilize, improve, and expand our platform.
