This highlights the operational aspect of managing design systems and cross-functional workflows, which is crucial for operations professionals. The emphasis on "gaming" also points to a specialized creative operations niche.

📈 Primary Responsibilities

• Ensure strict adherence to brand guidelines and visual identity across all marketing materials and digital products.

• Work with retouching and graphic assets to produce polished and professional visual content.

📝 Enhancement Note: The responsibilities listed are typical for a Senior UI Designer, but the emphasis on "creating new projects bordering on games," "creating and controlling libraries and Style Guide," and "Work closely with Front-end" indicates a need for strong operational execution and system thinking, aligning with a Design Operations perspective. The role requires not just creative output but also the management and standardization of design assets and processes.
