Junior UI/UX Designer (Freelance) – 3 Months – Brussels
Where Builders Build the Future
At RELYzIT Talent, we don't recruit — we build. We unite the top 2% of builders — engineers, architects, creators — into a movement across Europe and the GCC. Vetted through our VECTOR7 Signal Stack, you're not just hired, you're chosen. This is more than work. This is where builders build the future.
About the Role
We are seeking a Junior UI/UX Designer (Freelance) to join our client's mission-critical project in Brussels. This is a unique opportunity to lay the foundations for a unified Design System that will power a complex ecosystem of applications used by both the public and internal teams. Your work will directly impact the daily experience of city agents and partners, shaping the digital backbone of a major European capital.
Why This Role Matters
Our client's application ecosystem has grown organically, resulting in visual and ergonomic inconsistencies that hinder user experience and increase maintenance complexity. As a UI/UX Designer, you will be instrumental in creating a single source of truth for all interfaces, reducing UI/UX debt, ensuring accessibility, and enabling faster, more cohesive product development. Your contribution will set the standard for digital excellence and accessibility in the public sector.
What You'll Be Doing
* Conducting a comprehensive audit and inventory of existing UI/UX across key applications, identifying inconsistencies and usability friction points.
* Defining visual foundations, including color palettes, typography, spacing systems, and other design tokens to establish a robust brand identity.
* Designing and building an accessible, scalable UI component library (UI Kit) in Figma, leveraging best practices such as auto-layout, variants, and variables.
* Ensuring all components are WCAG-compliant and responsive, with a desktop-first approach and seamless mobile consultation experience.
* Documenting clear usage guidelines for each component, integrating documentation directly in Figma or via external tools as needed.
* Collaborating closely with product management and development teams to ensure the Design System accelerates delivery and maintains consistency.
* Delivering all phases and outputs within a structured, phased project plan, from audit to final documentation.
* Working in a hybrid model, with a minimum of 2 days per week on-site in Brussels.
What We're Looking For
* 1–3 years of experience in UI/UX design, ideally with exposure to complex, multi-application environments.
* Proven ability to audit and analyze existing UI/UX, identifying gaps and opportunities for improvement.
* Experience designing and implementing Design Systems or UI Kits, preferably for enterprise or institutional applications.
* Intermediate proficiency in Figma, including advanced features such as auto-layout, variants, variables, and shared libraries.
* Understanding of front-end technical constraints and collaboration with development teams.
* Knowledge of accessibility standards (WCAG 2.1 or 2.2) and a commitment to inclusive design.
* Experience documenting Design Systems and creating clear, actionable guidelines for usage.
* Familiarity with desktop-first business applications; experience with mapping or cartographic applications is a plus.
* Ownership mindset, strong problem-solving skills, and a drive to deliver impactful, future-proof solutions.
* Portfolio demonstrating relevant projects (Design Systems, UI Kits, business or institutional applications) is required.
