UI/UX Designer, Senior

Master Works is seeking a Senior UI/UX Designer & Frontend Developer to design and deliver the user experience for AI-powered analytics platforms deployed at major government and enterprise clients.

The role combines product design with hands-on frontend engineering — translating complex data and AI outputs into intuitive, bilingual (Arabic/English, RTL/LTR) interfaces that operate reliably in mission-critical environments.

The role is central to the success of multiple flagship platforms across the data, analytics, and intelligence portfolio.

Lead the end-to-end UX design process — user research, journey mapping, wireframes, interactive prototypes, and pixel-perfect mockups — for analyst, supervisor, and administrator workflows.

Build and maintain production-grade React/TypeScript frontends, ensuring responsive layouts and high performance across modern browsers.

Design and engineer a fully bilingual experience (Arabic/English) with first-class RTL support using CSS logical properties, locale-aware components, and persistent language preference.

Build complex data-rich interfaces — including media review tools, alert and queue management, annotation workflows, and split-panel review experiences.

Design and implement analytical dashboards using composable charting libraries — trends, distributions, heatmaps, performance scoring, and workload kanban views with load indicators.

·Establish and maintain a shared design system (typography, colour, spacing tokens, dark/light themes, component library) consistent with corporate and client brand guidelines and reusable across multiple products.

Ensure WCAG 2.

1 AA accessibility compliance — keyboard navigation, focus management, screen-reader semantics, colour-contrast ratios, and bilingual readability.

Collaborate closely with backend, AI/ML, and data engineers to define API contracts, error and loading states, and empty states; consume REST endpoints via typed clients.

Conduct usability testing with end users and business stakeholders, and translate findings into iterative UI improvements.

Work within containerised deployment workflows with awareness of operating in regulated, secure, or air-gapped environments where applicable.

Contribute to documentation: design specifications, component usage guidelines, user manuals, and onboarding materials for new joiners and end users.

Champion design quality across the team — review pull requests for UI changes, mentor junior frontend developers, and uphold consistency across product surfaces.

Bachelor’s degree in Computer Science, Software Engineering, Human-Computer Interaction, Interaction Design, Visual Communication, or a related discipline.

Postgraduate qualification (MSc/MA/MBA) in Design, Human-Computer Interaction, or a related field is preferred.

Recognised certifications in UX (Nielsen Norman Group, Interaction Design Foundation), accessibility (CPACC/WAS), or modern frontend frameworks are a strong plus.

5–7+ years of combined experience as a UI/UX designer and frontend developer, with at least 3 years shipping production React applications.

Demonstrable portfolio of complex enterprise or government-grade web applications, ideally including bilingual (Arabic/English) and RTL interfaces.

Hands-on experience with modern React, TypeScript, utility-first CSS frameworks (e.

g., Tailwind), modern build tools, and standard charting libraries.

Proficient in Figma (or equivalent) for design systems, prototyping, and developer hand-off; fluency with design tokens and component-driven workflows.

Exposure to data-rich interfaces — dashboards, queues, video review tools, annotation interfaces, or alert-management systems — is strongly preferred.

Working knowledge of accessibility standards (WCAG 2.

1), i18n/localisation frameworks, and version control (Git).

Familiarity with containerised frontends and an appreciation of operating in regulated or secure environments is a strong plus.

Excellent leadership and team development skills.

Strong user-centred design mindset; comfortable working directly with end users and translating ambiguous needs into clear, validated solutions.

High attention to visual and interaction detail, balanced with pragmatic engineering judgement and the ability to ship.

Excellent verbal and written communication, with the ability to present design decisions to both technical and non-technical stakeholders.

Collaborative team player; comfortable in cross-functional teams of designers, ML engineers, backend developers, and client business owners.

Self-directed and able to manage multiple concurrent projects with shifting priorities.

Cultural awareness and sensitivity, particularly when designing for Arabic-speaking users in regional contexts.
