UI/UX Designer Job Description

Key skills

Responsibilities

• • Conduct user research and usability testing to ground design decisions in real needs
• • Define information architecture, user flows, and interaction patterns
• • Create wireframes and interactive prototypes to explore and validate solutions
• • Design polished, consistent, accessible high-fidelity interfaces
• • Build and contribute to a scalable design system
• • Balance user needs, business goals, and technical constraints
• • Collaborate closely with product managers and engineers from discovery to delivery
• • Iterate on designs based on user feedback, data, and stakeholder input

Requirements

• • 3+ years designing digital products with a strong portfolio across UX and UI
• • Demonstrated ability across research, flows, prototyping, and visual design
• • Advanced proficiency in Figma or a comparable design tool
• • Experience validating designs with users rather than relying on taste alone
• • Working knowledge of accessibility and responsive design
• • Strong collaboration skills with product and engineering

Nice to have

• • Experience building or owning a design system
• • Basic understanding of HTML/CSS to design buildable interfaces
• • Prototyping or light motion-design skills
• • Experience as the sole or early designer on a small team

What to look for in a great UI/UX Designer

Many candidates claim both UX and UI strength but lean heavily one way, so evaluate both independently through the portfolio: look for thoughtful research and flows alongside polished, consistent visuals. The best UI/UX designers validate decisions with real users rather than relying purely on taste, so probe how they test and iterate. Systems thinking is a strong signal — designing reusable components rather than one-off screens. Collaboration matters because design lives at the intersection of product and engineering. For smaller teams especially, prioritize designers who can take a problem from ambiguity to a shipped solution with minimal hand-holding.

Interview questions to ask a UI/UX Designer

Walk through their portfolio and ask them to explain both the UX reasoning (research, flows, decisions) and the UI execution (visual choices, systems) behind a project. Give a small design exercise and observe how they balance user needs, business goals, and constraints. Ask how they validate designs with users and what they do when research contradicts their instincts. Probe systems thinking with a question about designing a reusable component. Finally, ask about a design that failed or tested poorly and how they responded, which reveals humility and an evidence-driven mindset.

Where to source UI/UX Designers

Portfolio platforms like Dribbble and Behance, plus personal sites, are the natural evaluation grounds. Design communities on Slack, Designer Hangout, and ADPList surface practitioners. LinkedIn searches filtered by product design and Figma experience help qualify candidates. The portfolio is the most reliable signal, since it reveals both research depth and visual craft. Referrals from product managers and engineers who have worked with effective designers are valuable. For sole-designer roles, prioritize candidates with end-to-end experience who can operate independently across the full design process.
