About the project

We're looking for a UI/UX designer to redesign the configuration menu of an existing 3D product configurator. The configurator is used by clients to visualize and customize furniture/outdoor product lines in real time. 
 

https://www.tuuci.com/designstudio/
 

Current State

The existing menu is outdated, unnecessarily complex and creates usability challenges due to limited guidance for new users. It can also prevent the team from introducing new features. The current main goal for customer is to configure each product on the scene individually, rather than product composition as a whole, which can’t be done with the current menu set up.

Scope of Work

• Audit of the current configurator UX/UI (we will provide details on main pain points and any context that needed)
• User flow mapping for the new "configure by element" experience
• Wireframes and interactive prototypes
• UI design aligned with existing brand guidelines

• Design handoff documentation for development (specs, states, edge cases)

   

Deliverables

• UX audit summary
• User flow diagrams
• Wireframes (low-fi)
• Interactive prototype (e.g., Figma)

• Final high-fidelity UI designs, including all component states (default, hover, selected, disabled, error)

   

What we're looking for

• Strong portfolio in configurator, e-commerce or product customization UX 
• Experience designing complex interfaces 
• Comfort working with 3D/visual product data and real-time preview systems
• Ability to simplify complexity without removing functionality
• Familiarity with component-based design systems
• Strong communication skills (a collaborative process with our internal team and stakeholders)
