UI/UX Designer - CAD Interfaces

Research & Development Digital Labs (Raddlabs) is seeking a UI/UX Designer to contribute to the design of a browser-based 3D engineering and design platform. The role is ideal for a creative, technically minded designer who can turn complex workflows into clean, intuitive user interfaces that align with the engineering and visualisation tools built in Unity WebGL.

This is a short-term contract role (approx. 20 hours per week for 7-8 weeks) suited to someone experienced in designing interaction models for Unity-based 3D applications, with familiarity in game-style interfaces and CAD or parametric-style design tools.

Role Overview

The UI/UX Designer will be responsible for creating the platform’s user interface layout, interaction flow, and design system in collaboration with developers, CAD specialists, and project stakeholders. The goal is to deliver a professional, accessible, and highly usable interface that simplifies the user experience of complex engineering and visualisation tools.

Key ResponsibilitiesUI / UX Design & Interaction

• Design interface layouts, panels, and control structures suitable for Unity-based 3D environments
• Define interaction patterns for:
• Object selection
• Parameter input
• Constraints and dependencies
• Visual feedback and system responses
• Structure interfaces that balance:
• Functional depth
• Visual clarity
• Predictable user behaviour
• Translate abstract rules and configuration logic into approachable interaction models

Parametric & CAD-Inspired Interface Design

• Design UI concepts that expose parametric options and rule-driven behaviour clearly
• Represent dependencies and constraints in ways that reduce user confusion
• Propose visual cues that help users understand cause-and-effect when values change
• Align interface concepts with how geometry and configuration logic behave in practice

Prototyping & Design Artefacts

• Produce low- to mid-fidelity artefacts such as:
• Wireframes
• Interaction flow diagrams
• Click-through or animated prototypes (tooling flexible)
• Iterate designs based on internal feedback and usability discussion
• Document key UI patterns and interaction decisions to support downstream implementation

Qualifications

• 3+ years of experience in UI/UX design for web or application interfaces.
• Proficiency with design tools such as Figma, Adobe XD, or Sketch.
• Strong understanding of UI layouts, hierarchy, accessibility, and responsive design principles.
• Experience working on data-heavy or 3D/technical interfaces preferred but not essential.
• Familiarity with Unity, WebGL, or engineering/visualisation tools will be highly regarded.
• Ability to collaborate effectively in a remote Agile team environment.

Key Competencies

• Strong ability to express complex functionality through clear interaction concepts
• Clean, modern visual design sensibility
• Thoughtful approach to hierarchy, feedback, and user guidance
• Clear written and verbal communication skills
• Ability to work independently within a short, clearly scoped contract
• Practical, delivery-focused working style
• Comfortable collaborating in a remote, asynchronous team setup
• Excellent communication and attention to detail
• Strong organisational and time management skills
• Ability to balance usability, aesthetics, and technical feasibility
• Self-directed, reliable, and efficient in a remote role

Why Work With Raddlabs

• Contribute to a high-impact digital engineering project shaping how structural design and automation tools are experienced.
• Enjoy flexible remote contract work with a collaborative and supportive team.
• Opportunity for repeat engagement on future projects and platform phases.
