• Experience analyzing and optimizing shaders using Shader Graph, Amplify Shader Editor, or HLSL
• Strong understanding of rendering costs: draw calls, overdraw, batching, culling, LOD systems, shadow rendering
• Experience optimizing HDRP features like lighting, post-processing, volumetric effects
• Good understanding of GPU optimization techniques and rendering budgets
• Very good knowledge of C# in Unity, especially runtime performance and memory management
• Experience reducing garbage collection, memory allocations, and CPU spikes
• Practical knowledge of asset optimization: textures, meshes, materials, animations
• Ability to diagnose and resolve memory usage and resource management issues
• Hands-on profiling and optimizing for PlayStation 5 and Xbox Series X|S
• Participation in at least one completed or shipped console title
• Familiarity with console-specific profiling tools including PIX and platform development tools

• Experience with third-person action-adventure or visually demanding 3D titles
• Passion for games and understanding of visual quality vs. performance balance

• Profile, analyze, and optimize game performance across CPU, GPU, and memory usage
• Identify and resolve performance bottlenecks, frame time spikes, FPS drops, and stuttering issues
• Optimize rendering performance in Unity HDRP, including shaders, lighting, shadows, post-processing, and volumetric effects
• Analyze and optimize shaders created with Shader Graph, Amplify Shader Editor, and HLSL
• Profile and optimize game builds directly on target hardware including PlayStation 5 and Xbox Series X|S
• Optimize C# code, memory allocations, and garbage collection to improve runtime performance
• Analyze and optimize game assets, including textures, meshes, materials, and animations
• Adjust graphical settings and rendering budgets to meet performance requirements per platform, especially Xbox Series S
• Conduct performance audits and develop structured optimization plans
• Establish and maintain target frame rates, frame time budgets, and memory budgets across supported platforms
• Measure, document, and communicate optimization results using performance comparisons
• Collaborate closely with Programmers, Technical Artists, and Art teams to resolve performance issues
