Job summary

World Wide Technology is seeking a Senior UX Designer to lead design on web and mobile platforms, grounded in user research and usability testing. You will design within the Blue Steel system, prototype interactively using agentic tools, and contribute to the design system and shared components.

The role requires strong Figma skills, experience with design systems, and the ability to mentor others while delivering high-quality UX across projects.

Qualifications

• Minimum 5 years of professional UX and UI design experience, including senior or lead responsibility on shipped software.
• Excellent design skills: typography, layout, color theory.
• Demonstrated ability to use agentic coding tools to produce working UI prototypes.
• Proven experience designing for both web and mobile.
• Ability to conduct user research and testing, run heuristic evaluations, recognize usability patterns and promote best practices.
• Ability to take an idea from concept to wireframe to final prototype, incorporating feedback throughout.
• Expert-level Figma skills, including component libraries, variants, auto layout, variables and prototyping.
• Proven experience designing within an established design system — and contributing components back to one.
• Working knowledge of how design systems are built, governed and adopted.
• Portfolio of recent work needed with application for consideration.

Responsibilities

• Act as the authoritative voice on UX and UI for the software projects you support, across web, mobile, desktop, internet and intranet platforms.
• Set direction for user-centered design activities — usability studies, personas, journey maps, concept testing — and coach teams on running them well.
• Analyze research results and present findings and recommendations to stakeholders and project teams, connecting design decisions to user and business outcomes.
• Mentor other designers, run critiques, and raise the bar on craft across the team.
• Develop and evangelize UX best practices, and make sure they land in the products we build.
• Keep the UX team ahead of product needs, finding new ways to support a constantly evolving set of requirements.
• Use agentic coding tools to build functional, interactive UI prototypes that teams can click through, test with users, and hand to engineering.
• Move from concept to wireframe to working prototype, gathering feedback from peers, developers and stakeholders along the way.
• Read and reason about front-end code well enough to make realistic design decisions, scope trade-offs with engineers, and produce prototypes that reflect what will actually ship.
• Contribute to and help maintain the corporate design system used across platforms, including its coded components.
