The Opportunity
We're looking for a Unity Developer to help build high-quality mobile games faster and smarter. Reporting to the Lead Unity Developer, you'll use modern AI development tools alongside your technical expertise to implement game features, prototype ideas rapidly, solve complex engineering problems, and continuously improve development velocity.
This role spans the entire game development lifecycle, from rapid prototyping to live operations. Success requires strong Unity fundamentals, excellent engineering judgment, and the ability to use AI as a force multiplier while maintaining high standards for code quality, performance, and player experience.
This position is remote and from Brazil.
What You’ll Be Doing
- Develop and implement mobile games in Unity for iOS and Android.
- Use AI-powered development tools to accelerate coding, debugging, refactoring, documentation, testing, and prototyping while maintaining production-quality standards.
- Collaborate with designers, producers, artists, backend engineers, and QA to deliver polished player experiences.
- Write clean, scalable, maintainable C# code and validate AI-generated code before production use.
- Rapidly prototype gameplay mechanics and iterate based on team feedback.
- Optimize performance across a wide range of mobile devices using Unity profiling tools.
- Debug complex gameplay, networking, memory, and platform-specific issues.
- Implement gameplay systems, UI, animations, VFX, audio, and live operations features.
- Contribute to CI/CD, build automation, and deployment pipelines.
- Review code, improve engineering standards, and contribute to reusable systems and internal tools.
- Continuously evaluate new AI tools and workflows that improve team productivity.
- Participate in Agile development processes, including sprint planning and daily standups.
What We’re Looking For
What you need to have:
- Bachelor's degree in Computer Science, Software Engineering, Interactive Media, or equivalent experience.
- 5+ years developing mobile games with Unity.
- At least 2 shipped mobile game titles.
- Excellent C# programming skills.
- Strong understanding of Unity architecture, UI Toolkit/uGUI, prefabs, asset management, animation, audio, and scene management.
- Experience building both 2D and 3D mobile games.
- Experience optimizing CPU, GPU, memory, and battery performance.
- Experience with REST APIs, WebSockets, or multiplayer networking.
- Strong debugging and problem-solving skills.
- Experience working in Agile teams.
- Excellent communication and collaboration skills.
AI-First Development
We expect our engineers to use AI as part of their daily workflow. You should:
- Be comfortable using AI coding assistants (such as Unity AI, GitHub Copilot, Cursor, Claude Code, ChatGPT, or similar).
- Know how to write effective prompts for technical tasks.
- Critically review, validate, test, and improve AI-generated code rather than accepting it blindly.
- Use AI to accelerate debugging, documentation, testing, refactoring, and code generation.
- Continuously experiment with new AI workflows that improve development speed without compromising quality.
- Understand the limitations, risks, and security considerations of AI-assisted software development.
