Design Engineer (UX / UI)

UX/UI Engineer

Location: Sydney, Australia (Hybrid - 3 days in office per week)

At Relevance AI, our mission is to empower anyone to delegate work to the AI workforce.

We're building a new type of automation platform, for anyone to create and use AI agents that can replicate human quality work, decision making and collaboration.

We are scaling fast to meet unprecedented customer demand and we need exceptional talent to help us grow. If you're ready to be part of a trailblazing company at the cutting edge of AI, this is the place for you.

The Role

We're hiring for a new type of engineer at Relevance AI. We're looking for UX/UI specialists and builders who care deeply about building intuitive, user-friendly, and highly polished experiences. You'll lead initiatives across the design lifecycle to conduct user research, rapidly prototype as well as implement elegant UI in code to accelerate delivery - owning components and interactions in production. If you identify more as a product designer who codes or a front-end engineer with strong UX/UI design instincts, you'll thrive in this role.

Think: mapping an agent-building flow in the morning, prototyping in Figma at lunch, and pushing a polished front-end experience to production by afternoon - instrumented, accessible, and measurable. You'll get to craft beautiful experiences across our agent building and orchestration platform, making powerful AI feel intuitive, transparent, and trustworthy.

Your Impact

• Collaborate closely with Product, Design, and Engineering to implement highly responsive, visually appealing and functional user interfaces while maintaining design fidelity.
• Build reusable front-end components and maintain our design systems, UI libraries, and front-end components to ensure consistency and scalability.
• Conduct user experience testing and iterate designs based on user feedback and analytics.
• Review designs for technical feasibility and propose solutions that balance UX and engineering constraints.
• Champion a high bar for UI/UX and mentor others on best practices, latest trends and coding standards.

What We're Looking For

• Strong front-end development and UX/UI background with experience building for complex platforms (e.g., no-code tools, automation software, or enterprise SaaS).
• Proficiency in HTML5, CSS3, and JavaScript, with hands-on experience across a range of front-end tooling (e.g., npm, Webpack, Tailwind, Redux, Jest) and familiarity with modern frameworks such as React, Angular, or Vue.
• Experience creating and maintaining design systems, reusable components, and UI libraries.
• A proven track record of tackling challenging product designs and taking ownership of initiatives from user research to concept/mock-up through to production.
• Strong visual design sense and a passion for building highly responsive, performant user interfaces.
• Thrive in dynamic, high-performance start up settings and comfortable with ambiguity, rapid iteration, and taking initiative.
