What they need
We are looking for a forward-thinking Senior Unity Game Developer to join our core team. In this role, you will lead systems architecture, optimize game performance, and spearhead high-efficiency workflows by pairing strong software engineering fundamentals with AI coding tools (e.g., Cursor, GitHub Copilot, Unity Muse).
Key Responsibilities
- Systems & Architecture: Design, write, and maintain scalable C# code for core gameplay mechanics, UI systems, and backend integrations.
- AI-Assisted Development: Leverage modern AI coding tools (Cursor, GitHub Copilot, JetBrains AI, etc.) to rapidly prototype features, refactor code bases, write unit tests, and generate boilerplate.
- Code Quality & Verification: Inspect, debug, and optimize AI-generated code to ensure strict adherence to memory management, performance, and game architecture standards.
- Performance Optimization: Profile and optimize CPU/GPU performance, draw calls, object pooling, and memory allocations for target platforms.
- Mentorship & AI Tooling: Guide team members on AI-assisted coding best practices, prompt engineering for game logic, and maintaining code safety/standards.
Requirements
- Experience: 5+ years of professional game development experience, with at least 3+ years focused on Unity and C#.
- AI Tooling Expertise: Proven experience integrating AI coding assistants (e.g., Cursor, GitHub Copilot, ChatGPT/Claude for architecture) directly into your daily IDE workflow.
- Technical Foundation: Deep understanding of Unity internal architecture, execution order, assembly definitions, design patterns (SOLID), and graphics pipelines (URP/HDRP).
- Critical Code Review: Strong ability to evaluate, debug, and refactor code generated by LLMs to avoid subtle bugs, race conditions, or performance bottlenecks.
- Shipped Titles: Credit on at least one published commercial title using Unity.
Nice to Haves
- Experience with Unity Muse, Unity Sentis, or custom Model Context Protocol (MCP) plugins in Unity.
- Experience setting up custom project rules (.cursorrules / .copilotignore) for codebase-aware AI prompting.
- Shader development (HLSL / Shader Graph) or multiplayer networking frameworks.
