We're seeking a technically-minded UI/UX Designer to join our team, focusing on the implementation and technical execution of digital front-end solutions. This role emphasizes translating design concepts into production-ready specifications, working closely with development teams, and ensuring pixel-perfect implementation of user interfaces.

Unlike traditional product design roles, this position prioritises technical precision, design system adherence, and developer handoff quality over conceptual creative work.

• Create production-ready UI specifications and detailed design documentation for development teams
• Build and maintain component libraries and design systems in Figma
• Produce precise redlines, measurements, and technical annotations for front-end implementation
• Define interaction states, responsive breakpoints, and technical behaviors for UI components
• Ensure consistency and technical accuracy across all digital touchpoints

• Maintain and evolve existing design systems with focus on scalability and developer efficiency
• Document component usage, variants, and technical specifications
• Create and maintain style guides covering typography, color systems, spacing, and grid structures
• Audit existing interfaces for design system compliance and consistency

• Work closely with front-end developers to ensure accurate implementation of designs
• Conduct QA reviews of implemented designs and provide technical feedback
• Bridge communication between design and development teams
• Create clear handoff documentation using Figma's dev mode and inspection tools

• Prepare and optimise design assets for various platforms and screen densities
• Export production-ready assets in appropriate formats (SVG, PNG, etc.)
• Create icon sets and graphical elements using Adobe Illustrator
• Ensure all assets meet technical requirements for performance and accessibility

• Plan, create, and conduct usability testing sessions to validate design implementations
• Develop testing protocols and scenarios for evaluating implemented features
• Analyse testing data and user feedback to identify implementation issues
• Create comprehensive testing reports with actionable recommendations for improvements
• Conduct post-implementation research to measure design effectiveness and user satisfaction
• Document findings and iterate on designs based on real-world usage data

• 3+ years of UI/UX design experience with strong focus on technical implementation
• Expert proficiency in Figma, including auto-layout, components, and variables
• Strong working knowledge of Adobe Creative Suite (particularly Illustrator and Photoshop)
• Deep understanding of responsive design principles and grid systems
• Solid grasp of HTML/CSS capabilities and constraints (coding ability not required)
• Experience creating and maintaining design systems at scale
• Ability to conduct user research, analyse data, and translate findings into design solutions
• Proven ability to plan and conduct usability testing and create actionable testing reports
• Experience with implementation research and post-launch validation methods
• Meticulous attention to detail and pixel-perfect execution
• Strong documentation and specification skills
• Excellent communication and collaboration skills to work effectively with developers and other team members

• Experience with design tokens and design-to-code workflows
• Familiarity with front-end frameworks (React, Vue, etc.) and their component structures
• Understanding of accessibility standards (WCAG 2.1 AA)
• Experience with prototyping tools and interactive design
• Knowledge of version control concepts (Git/Git Hub)
• Basic understanding of design handoff tools (Zeplin, Avocode, etc.)
• Familiarity with usability testing tools and platforms (User Testing, Maze, Hotjar, etc.)
• Experience with analytics tools for measuring design performance (Google Analytics, Mixpanel, etc.)
• Previous work on software for drone technology, robotics, or IoT systems
• Experience working in an Agile development environment
• Degree in Design, Human-Computer Interaction, or a related field

• Portfolio showcasing technical UI work, component libraries, and design systems
• Examples of detailed design specifications and developer documentation
• Evidence of systematic thinking and structured approach to design
• Understanding of design patterns and UI conventions
• Examples of usability testing reports and implementation research findings
• Ability to balance design quality with technical constraints

• Fluency in English is essential
• Flexible and adaptable to…
