• The role demands mastery of Figma, including advanced features like Auto Layout, variables, and design tokens, to create developer-friendly and scalable design systems.

• Responsibilities include ensuring pixel-perfect delivery, implementing visual hierarchy, typography, and color systems, and understanding mobile platform guidelines (iOS HIG and Material Design 3).

• Collaboration is key, with an async-first approach, working closely with Product and Engineering teams for efficient iteration and clean handoffs.

📝 Enhancement Note: The job title and description explicitly shift the emphasis from UX to UI execution. The company seeks candidates whose portfolios demonstrate tangible UI building skills for launched native apps, not just conceptual design work. This is a contract role with a clear 3-month initial term and a high likelihood of extension.

📈 Primary Responsibilities

• Platform-Specific UI Design: Execute UI designs for both iOS and Android, strictly adhering to Apple's Human Interface Guidelines and Google's Material Design 3 principles to ensure native look and feel.

• Figma Mastery & Component Library Development: Build and maintain a robust Design System within Figma, leveraging Auto Layout, variables, design tokens, and interactive components to ensure scalability and consistency.

• Developer-Friendly Handoff: Create meticulously detailed specifications, annotations, and ready-to-use assets within Figma's Dev Mode to facilitate seamless handoff to the engineering team, minimizing back-and-forth.

• Visual Quality Assurance: Proactively identify and rectify visual inconsistencies, ensuring optimal visual hierarchy, typography, spacing, and color application across the app.

• UI Motion Integration: Implement basic UI motion principles, including transitions and micro-interactions, to enhance user experience without requiring deep specialization in animation.

• Async-First Collaboration: Engage effectively with Product Managers and Engineers in an async-first environment, prioritizing clear documentation of decisions and efficient, iterative design processes.

• Pixel-Perfect Delivery: Ensure all delivered UI elements and screens meet the highest standards of visual accuracy and detail.

📝 Enhancement Note: The responsibilities are heavily weighted towards the practical, technical execution of UI design within Figma and adherence to platform standards. The emphasis on "developer-friendly" and "pixel-perfect" delivery highlights the need for precision and efficiency.
