• • Demonstrated experience building or contributing to a design system
• • Strong grasp of visual hierarchy, typography, color, and layout fundamentals
• • Working knowledge of accessibility principles as they apply to visual design
• • Ability to collaborate closely with UX designers and engineers through handoff

Nice to have

• • Basic understanding of HTML/CSS to inform realistic, buildable designs
• • Motion design or prototyping skills for interaction-heavy interfaces
• • Experience designing for both web and native mobile platforms
• • Illustration or custom iconography capability

What to look for in a great UI Designer

A strong portfolio is the single best signal — look for consistency, attention to detail, and evidence of systems thinking rather than a collection of disconnected pretty screens. Ask candidates to walk through a design and explain their decisions: why this spacing, why this type scale, why these states. The best UI designers care about accessibility and buildability, not just aesthetics, and can talk about constraints they designed within. Watch for how they handle a component used in many contexts — strong candidates think in reusable systems, not bespoke one-offs. Collaboration cues matter: do they speak respectfully about working with engineers and UX peers?

Interview questions to ask a UI Designer

Walk through their portfolio and ask them to defend specific decisions — probe the reasoning behind type scales, color choices, and component structure. Give a small design exercise such as redesigning a cluttered screen, and observe how they establish hierarchy and reduce noise. Ask how they would design a button component that needs to work across many states and contexts; this tests systems thinking. Probe their accessibility awareness with a question about color contrast or focus states. Finally, ask about a time they disagreed with an engineer about feasibility and how they resolved it.

Where to source UI Designers

Dribbble, Behance, and personal portfolio sites are the natural hunting grounds — visual work speaks for itself in this discipline. Designer communities on Twitter/X, Designer Hangout, and Figma community files surface active practitioners. LinkedIn searches filtered by Figma and design systems experience help qualify candidates. Referrals from your existing design team are valuable since taste and craft are hard to assess remotely. For senior hires, look for designers who have built and documented design systems or who write thoughtfully about their craft, which signals depth beyond surface aesthetics.
