UI/UX Designer

UI/UX Designer

About the Project

Join a specialist software development team delivering a new, business-critical technology platform for an established international organisation. This greenfield project involves modern cloud architecture, data-intensive applications, and AI-enabled capabilities. You will work within a multidisciplinary team alongside experienced software, AI, infrastructure, and design professionals, taking the platform from development through to production. The project is for a live business environment, so security, scalability, maintainability, data protection, and production readiness are essential throughout.

Role Purpose

As a UI/UX Designer, you will design accessible, maintainable interfaces for complex web applications. Your responsibilities will span user research, information architecture, interaction design, visual design, reusable components, and developer hand-off. You will translate requirements into behaviour that can be implemented and tested, working closely with software engineers and the Technical Lead.

Main Responsibilities

• User Research and Information Architecture: Plan interviews and task-based research, distinguish observed user needs from assumptions, and translate findings into journey maps and information architecture. Define navigation, terminology, and content hierarchy for clarity and efficiency. Ensure research findings inform design priorities and maintain confidentiality.
• Interaction Design and Prototyping: Produce wireframes, detailed interface designs, and interactive prototypes using Figma or an equivalent tool. Specify behaviour as well as appearance, including validation, loading, error, disabled, and permission-restricted states. Address feedback, error recovery, and workflow complexities in prototypes.
• Design Systems and Visual Design: Establish and maintain a reusable design system with consistent typography, spacing, colour, layout, and component behaviour. Document properties, variants, states, and usage guidance. Collaborate with engineers to ensure alignment between design assets and coded components.
• Accessibility and Responsive Design: Specify accessible interactions according to Web Content Accessibility Guidelines 2.2 level AA. Define responsive behaviour through layout rules and conduct manual accessibility testing, addressing findings before release.
• Engineering Collaboration and Hand-off: Prepare implementation-ready work ahead of development sprints, including approved components, interaction rules, content behaviour, accessibility annotations, and testable acceptance criteria. Review technical constraints and resolve questions during implementation.
• Usability Evaluation and Design Quality: Run task-based usability tests, assess completion and confusion points, and recommend evidence-based changes. Review implemented interfaces, record defects, and collaborate with engineers to resolve them. Maintain up-to-date design files and decision records.
• AI Assisted Interactions: Ensure proposed content, accepted information, source evidence, and human decisions are visibly distinct. Support inspection, correction, acceptance, rejection, and deferred review in designs, and provide clear interface wording for next actions.

Essential Technical Experience

• Substantial professional UI/UX experience with production web applications, including responsibility for research, interaction design, and delivery.
• Portfolio demonstrating implemented work, personal contribution, addressed constraints, and user feedback-driven improvements.
• Advanced proficiency in Figma or equivalent, including reusable components, variants, layout constraints, shared styles or variables, and interactive prototyping.
• Experience building or maintaining a design system and collaborating with engineers for consistent application in component-based applications.
• Practical experience in user research, information architecture, responsive design, and accessibility.
• Ability to explain interaction states, provide clear developer specifications, evaluate implemented behaviour, and prioritise usability defects.
• Comfortable working independently within a multidisciplinary team and discussing design trade-offs with technical colleagues.
• Experience designing complex workflows, data-heavy interfaces, and permission-sensitive interactions.

Desirable Experience

• Experience with React or Next.js teams and coded component libraries.
• Experience in accessible data visualisation, localisation, and usability research involving assistive technologies.
