Lead UI/UX Designer, Zalo

This role demands a Strategic System Thinker who defines how design impacts the entire ecosystem. Beyond individual features, you are responsible for the architectural integrity of the platform and the efficiency of the design-to-development workflow. You bridge the gap between high-level business goals and technical feasibility.

• Lead Essential User Journeys: Steer the design of core functionalities by actively partnering with POs to define the right development approach. Whether strategizing a rapid MVP or a comprehensive full-process feature, you drive the UX vision, ensuring the fundamental app experience remains logically structured without falling into a reactive, request-taking dynamic;
• Define Visual Principles: You don't just use the design system; you evolve it. You decide which principles to apply (or break) to solve specific platform problems. You define the "Why" behind the "Look.";
• Deep Interaction Design (HCI): Apply advanced UX Laws and HCI principles to design detailed micro-interactions and transitions. You ensure the system gives feedback (system status) that is psychologically satisfying and clear to the user;
• Evidence-Based Design: You validate your design decisions using qualitative research and available quantitative data. You don't guess; you look for evidence to prove why a flow will work;
• Heuristic & Proactive Audit: Proactively perform Heuristic Evaluations on existing products. You identify UX debts in the platform and propose solutions to the Product Team without waiting for a ticket;
• Roadmap Contribution: You sit with Product Managers and Tech Leads during planning. You understand technical constraints (Road-blocks) well enough to propose design solutions that are feasible yet innovative;
• Master of Storytelling: You set the context. When presenting to Stakeholders, you don't just show screens; you tell the story of the user's problem, the business constraint, and how your solution bridges the gap;
• Host Design Critiques: You lead high-quality critique sessions. You create a safe environment where designs are debated based on logic and principles, helping Senior/Junior members improve their craft;
• Process Optimization: You observe how the Design, Product, and Dev teams interact. You propose and build workflows that reduce friction and improve delivery speed for the Platform team.

• Experience: 5+ years in UI/UX Design, with at least 2 years leadership;
• System Thinking: You see the ecosystem, not just the page. You understand how a change in the Payment module affects the Mini App experience;
• Psychology & HCI: Deep understanding of human behavior. You know how to use design to reduce cognitive load in complex data dashboards;
• Logic & Evidence: You prioritize logic over aesthetics. You are comfortable defending your design using data points (e.g., Retention dropped by X%, so we need to change this flow);
• High-Scale Consumer Apps: Proven experience designing for core product functionalities with massive user bases (e.g., Social, Messaging, Core Utilities). You know how to craft flawless, high-performance experiences that millions interact with daily;
• Prototyping & Motion: Ability to build high-fidelity prototypes that mimic real-life interactions (motion, transition) to prove a concept to Developers;
• Design System Leadership: Experience in maintaining and scaling a Design System for multiple products;
• Debate & Persuasion: Ability to debate design choices with Product Managers and Engineers. You can explain complex UX concepts in simple business terms;
• Mentorship: A track record of guiding less experienced designers, helping them improve their logical thinking and visual output.
