Core skills
Required skills
Optional skills
As our design and engineering teams scale, consistency and speed become our ultimate competitive advantages. We are looking for a highly technical and detail-oriented Design System Designer to take full ownership of our Global Design System. You will be the bridge between design, engineering, and marketing, transforming fragmented UI elements into a robust, scalable, and modular architecture. Your immediate challenge will be finalizing our design system rework and componentizing our core CFD product so that we can rapidly assemble a new, standalone Crypto product using the same underlying blocks. If you are a Figma wizard who thinks in tokens, components, and code, and loves building the tools that empower others to create faster and better, this role is for you. Responsibilities Audit the current UI files, identify fragmented components, and consolidate them into the unified Global Design System Design, build, and maintain all core components, patterns, and templates in Figma, ensuring they are scalable and responsive Write clear, exhaustive documentation for the Design System, defining the "do’s and don’ts" for designers and engineers Act as a reviewer for design files created by Product and Marketing Designers before developer handoff, ensuring strict adherence to the Design System Onboard new designers and engineers to the system, conducting training sessions on how to use variables and components efficiently Requirements 4+ years of Product Design experience, with at least 2+ years dedicated entirely to building and managing complex Design Systems for scalable Web and Mobile applications. Absolute mastery of Figma: deep expertise in variables, design tokens, component variants, interactive components, and advanced auto-layout. Strong technical understanding of front-end development (HTML/CSS, React, React Native, iOS/Android constraints). You don’t need to write production code, but you must speak the same language as engineers. Experience with multi-theming (light/dark mode) and white-label/multi-brand architectures. Experience setting up and maintaining synchronization tools between design and code (e.g., Storybook, Zeplin, Figma API, or Token Studio). Systems Thinking: You don't just see a "button"; you see its states, padding rules, accessibility constraints, and how a change to it will cascade across 500 screens. Diplomacy & Guardrails: You know how to gently but firmly say "no" to custom components requested by other designers, keeping the system clean and standardized. Attention to Detail: Pixel perfection is your baseline. You care deeply about alignment, typography scales, and accessibility (WCAG) contrast ratios. Documentation Champion: You believe that a component without clear usage guidelines is a useless component. Will be a plus Experience specifically in FinTech, Trading, or Crypto platforms with high-density data visualization (charts, order books, complex tables) Ability to write basic code (CSS, JS, React) to contribute directly to the Storybook repository Experience leveraging AI tools to automate component generation or documentation writing We offer 20 paid vacation days per year 10 paid sick leave days per year Public holidays as per the company’s approved Public holiday list Medical insurance Opportunity to work remotely Professional education budget Language learning budget Wellness budget (gym membership, sports gear and related expenses)
