[Remote] 3D Game Prototype Developer (Unity/English)

Job description

We are looking for a Unity developer who can turn casual/hypercasual game ideas into playable 3D prototypes quickly, taking a concept to a testable build in days, not months. You'll work on fast iteration loops to validate the "fun factor" of mechanics similar to puzzle, sorting, merge, and arcade-style mobile games.

RESPONSIBILITIES

• Rapidly build playable 3D game prototypes on Unity from concepts, references, or design briefs.
• Reproduce and adapt core gameplay mechanics from reference games to test new variations.
• Implement core loops, level systems, and basic UI fast, prioritizing playability over polish.
• Iterate quickly on mechanics, difficulty, and feel based on playtest feedback and metrics.
• Meet with the design team to scope ideas, clarify specifications, and propose technical approaches.
• Collaborate closely with Game Artists to integrate 3D assets, animations, and effects.
• Set up lightweight, reusable prototype templates and a development pipeline to speed up future projects.
• Write clean, efficient, and modular code that can be extended if a prototype gets greenlit.
• Ensure prototypes run smoothly on target mobile devices (stable framerate, reasonable load times).
• Identify and resolve gameplay bugs and performance bottlenecks quickly.
• Propose and implement technical solutions in a timely manner.
• Conduct white-box testing on prototype builds before handoff.

Your skills and experience

REQUIREMENT

• Bachelor's degree in Computer Science, Computer Engineering, or a related field (or equivalent practical experience).
• 2–4 years of experience as a Unity Developer, ideally including mobile game development.
• Hands-on experience building casual/hypercasual or puzzle-style games (a portfolio of prototypes or shipped titles is strongly preferred).
• Comfortable working in fast iteration cycles and an Agile/Scrum environment.
• Knowledge of AI-assisted development tools to accelerate coding.

SKILLS

• Proficiency in C# and the Unity engine.
• Solid grasp of 3D fundamentals: scripting, physics, animation, materials/textures, GUI styles, and scene management.
• Ability to quickly reverse-engineer and reimplement gameplay mechanics from reference games.
• Skill in optimizing memory and performance for mobile devices.
• Ability to use AI tools effectively to improve productivity and development workflow.
• Good English reading and writing skills for collaboration in an international environment.

ABILITIES

• Strong critical thinking and troubleshooting abilities.
• Ability to critically evaluate and adapt AI-generated solutions.
• A bias toward speed and experimentation, shipping a rough playable beats a perfect plan.
• Open-mindedness and willingness to learn and explore new technologies.
• Excellent attention to detail.
• Strong work ethic and trustworthiness.

Why you'll love working here

• Professional, creative working environment and talented teams; equal-opportunity & agile culture.
• Fully remote team, no traffic jam, no rigid office hours.
• Regular discussions and a chance to learn directly from experts in their fields.
• International exposure and real opportunity to grow.
