Senior UI/UX Designer, Zalo

This role demands a Systematic Thinker who can own a feature from concept to delivery. You will partner directly with PMs and Engineers to translate complex business requirements into intuitive, scalable, and logic-driven interfaces. You are not just a designer; you are a solution-shaper who ensures every interaction serves a clear purpose.

• Shape the UX Solution: Actively engage in the early stages of the workflow. Instead of letting others define the task scope, you evaluate the design brief and advise on the appropriate execution approach—whether it’s a quick hotfix, a lean MVP, or a full-process design. You ensure the system experience remains logical and prevent the Design Team from falling into a reactive, request-taking dynamic or feeling like an internal service;
• Apply & Evolve Visual Principles: You don't just use the design system; you contribute to its evolution. 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;
• 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;
• 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;
• Contribute to Design Critiques: You actively participate and provide high-quality input in critique sessions. You create a safe environment where designs are debated based on logic and principles, helping elevate the team's craft.

• Experience: 2-4+ years in UI/UX Design (Leadership experience is not required, but a strong sense of product ownership is essential);
• System Thinking: You see the ecosystem, not just the page. You understand how a change in one module affects the experience of another;
• Psychology & HCI: Deep understanding of human behavior. You know how to use design to reduce cognitive load in complex data dashboards or user flows;
• 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. 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;
• Debate & Persuasion: Ability to debate design choices with Product Managers and Engineers. You can explain complex UX concepts in simple business terms.
