About Us 🚀

At Relevance AI, we’re building the home of the AI workforce.

Our mission is simple: empower every team to delegate meaningful work to AI agents that think, act, and collaborate like experts.

With Relevance AI, anyone can create and manage intelligent agents that handle workflows, decisions, and collaboration - all within one unified platform. Our technology already powers industry leaders such as Canva, Databricks, Confluent, Autodesk, Lightspeed, Rakuten, Aveva, Qualified, and Activision Blizzard, helping them scale excellence across operations, marketing, and sales.

We’re backed by Bessemer Venture Partners, Insight Partners, Peak XV, and King River Capital, and raised our Series B in April 2025 to accelerate growth and push the boundaries of agentic automation.

Headquartered in San Francisco and Sydney, we operate on a hybrid model and thrive on curiosity, collaboration, and execution - we move fast, think big, and win together.

In 2025, we were proud to be named LinkedIn’s #1 Startup in Australia.

The Role 🥳

We’re hiring for a new type of product designer and 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.

What We’re Looking For 🧠

• 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.
