The Role

As Senior UI Designer, you will be the guardian of interface excellence across our brands and platforms. Working across websites, landing pages, tools, and marketing environments, your mission is to lead the visual evolution of our digital products while mentoring and inspiring the wider team.

You'll collaborate closely with product managers, UX designers, developers, and marketers to bring data-informed, intuitive, and engaging interfaces to life. This is a hands on role where you'll lead by doing - applying your design craft while creating systems, sharing knowledge, and helping establish design standards as we grow.

Key Responsibilities

• Lead visual design for mobile-first websites, landing pages, and product UIs across QiH brands.
• Develop and manage scalable design systems and UI libraries that ensure consistency across products while supporting rapid testing and iteration.
• Translate strategic goals, user needs, and data insights into polished, usable, and conversion-led UI solutions.
• Collaborate with Product, UX, development, and marketing teams to deliver cohesive, end-to-end journeys.
• Uphold consistency, accessibility, and best practices across all outputs.
• Act as a design leader and mentor to the wider team, offering regular feedback, guidance, and support.
• Contribute to the evolution of design processes and documentation.
• Help champion a culture of design by data, collaboration, and continuous learning.
• Stay ahead of UI trends, tools, and technologies, and bring fresh thinking to the team.

• Proven ability to lead UI work across multiple projects and stakeholders.
• An inspiring portfolio demonstrating excellence in UI design, including mobile-first, responsive web and conversion-led design.
• Expert in Figma and design system development.
• Strong understanding of front-end principles (you don't need to code, but you need to collaborate).
• Experience working with UX, product, and development teams in agile environments.
• A mentor's mindset - you love helping others grow and build confidence in their craft.
• Excellent communication, presentation, and problem-solving skills.
• A proactive, adaptable attitude and collaborative spirit.

Nice to Have

• Experience in performance marketing, iGaming, or fintech.
• Familiarity with creative automation tools (Bannerflow).
• Knowledge of accessibility standards (WCAG).
• Experience leading or supporting rebrand or product redesign initiatives.
• Light prototyping and motion design (e.g., Principle, After Effects).
