Freelance UI/UX Designer

RKS Design – Thousand Oaks, CA

Freelance / Contract | In-Office

About RKS Design

RKS Design is a global innovation and product-development firm with over 40 years of experience delivering breakthrough solutions across consumer, medical, industrial, and digital categories. We blend human-centered design, business strategy, engineering, and our proprietary Psycho-Aesthetics® methodology to create products, services, and experiences that resonate emotionally and perform commercially. Our team works end-to-end, from insight and strategy to design, engineering, and go-to-market execution.

Job Summary

We are seeking a mid-level UI/UX Designer to consult on a freelance basis who understands people as deeply as interfaces. At RKS, human-centered design begins with understanding people’s needs, motivations, aspirations, and behaviors—and translating that understanding into experiences that are intuitive, meaningful, and emotionally engaging.

You will apply Psycho-Aesthetics® (P/A), RKS’s proprietary human-centered design strategy methodology, alongside Eydora, our AI-powered strategy and decision-support platform, to turn research into clear design direction. This requires looking beyond usability to understand how an experience builds confidence, expresses identity, earns trust, and helps people achieve their goals. (eydora.ai)

Working across embedded touchscreens, device displays, companion mobile apps, web platforms, and software tools, you will connect digital interactions with the physical products and services around them. You will collaborate with Industrial Design, Engineering, Research, and Strategy to carry human insights through concept development, testing, and implementation.

What You’ll Do

• Understand people and context: Explore users’ needs, behaviors, emotional motivations, and aspirations, including the environments in which they interact with products.
  
• Apply Psycho-Aesthetics®: Translate research, personas, P/A mapping, and opportunity insights into interface priorities, interaction behaviors, and experience journeys.
  
• Incorporate Eydora into the design process: Use Eydora to support research synthesis, explore opportunities, examine assumptions, and inform design decisions, applying professional judgment and validating ideas with users.
  
• Design end-to-end experiences: Create user flows, information architecture, wireframes, and interactive prototypes for apps, web platforms, and on-device interfaces.
  
• Craft purposeful UI: Develop polished visual designs, icons, and interaction details that support accessibility, reflect each client’s brand, and connect with the product’s physical design language.
  
• Design for connected products: Create coherent experiences across embedded displays, touchscreens, physical controls, and companion applications, working within hardware and technical constraints.
  
• Build and maintain design systems: Develop reusable components, interaction patterns, style guides, and specifications that keep experiences consistent and scalable.
  
• Test functional and emotional outcomes: Evaluate whether people can use an experience effectively and whether it creates the intended understanding, confidence, trust, and engagement.
  
• Collaborate through implementation: Work closely with designers, engineers, and software developers to preserve the human-centered intent as concepts become working products.
  
• Prepare developer handoff: Deliver clear specifications, annotated designs, and assets, and support developers through implementation and design verification.
  
• Communicate design rationale: Present concepts in client workshops and design reviews, connecting recommendations to human insights, P/A strategy, business goals, and testing findings.
