Description du poste

A Belgian public-sector organisation develops and supports digital services used by public administrations, education stakeholders, professionals and citizens. As a UX/UI Designer focused on UX research, you will help establish a structured, reusable approach to understanding users, testing services and improving interfaces, with accessibility and a Design System as important reference points.

The mission

Administrative simplification is driving the development of digital services for a broad range of users. They include public-sector staff, education stakeholders, teachers, artists, sports professionals and citizens. Their needs, constraints and familiarity with digital services vary, so teams need a proportionate way to choose research and design activities. The organisation also audits the accessibility of the interfaces it provides, maintains a Design System and draws on previous project-specific UX studies.

You will contribute to a cross-service UX initiative covering internal business applications and services for the general public. You will map audiences, investigate their needs, uses and constraints, and help teams choose between light, standard and in-depth UX support. Light support can rely on known users, good practice and existing Design System patterns. Standard support can add targeted research or user testing. In-depth support applies to new services, broad audiences or complex journeys. You will turn research findings into practical guidance for UX and non-UX colleagues. Expected outputs include audience and persona references, a UX assessment grid, a catalogue of methods with templates, a testing and measurement approach, and recommendations for the Design System.

Your responsibilities

• Map the audiences and user profiles of digital services across public-sector domains.
• Conduct interviews, observations, questionnaires, focus groups and qualitative or quantitative analysis.
• Create personas and user journeys based on documented research findings.
• Define light, standard and in-depth UX support levels for each project.
• Build reusable UX methods, guides, templates and analysis grids for all teams.
• Define how to test solutions and measure user experience when needed.
• Help teams integrate research into project framing and apply the resulting recommendations.

Your profile

Essential skills:

• Experience in UX/UI design with a focus on UX research.
• Qualitative and quantitative user research methodology.
• User interviews, focus groups, observations and questionnaires.
• Personas, user profiles and user journeys based on research findings.
• User testing, prototype testing, Maze and A/B testing.
• Accessibility in digital services.
• Audience analytics tools, such as Google Analytics or Matomo.
• Prototyping and design tools, including Figma and FigJam.
• Agile methodology.
• Ability to turn research results into concrete recommendations and reusable UX methodologies.

Languages:

• French: native.

Working context

• Work closely with Design System and accessibility specialists, alongside communications colleagues responsible for shared digital identity.
• Create guidance that UX and non-UX colleagues can apply to their own projects.
• Adapt the depth of research to the audience, project complexity, key issues and existing knowledge.
• The mission is conducted exclusively in French.
