Decagon is the leading conversational AI platform, empowering every brand to deliver concierge customer experiences. Industry-defining enterprises like Cash App, Square, Chime, Oura, Delta Airlines, Tickemaster, American Airlines, and Avis use our platform to deploy AI agents that power personalized, deeply satisfying interactions across voice, chat, email, SMS, and every other channel. We believe businesses deserve better, more human ways to care for their customers, and that AI finally makes that possible. Design at Decagon is early and growing. You'd report to our Senior Director of Product Design and join a high-visibility, high-ownership team where your work directly shapes the product, the company, and the interaction patterns an entire industry is still figuring out. We work across every customer segment, partnering closely with engineering, product, and go-to-market to make our platform robust, scalable, and easy to use.

Today, enterprises use Decagon to deploy AI agents that handle millions of customer conversations. Where we're headed is bigger: making those agents something teams can shape, direct, and trust as naturally as they'd work with a great colleague. Nobody has solved the design problems in between. The surfaces where enterprises build, control, and come to trust autonomous agents don't have established patterns yet, and this role exists to invent them. This is an opportunity to define what great agent UX looks like, across chat, voice, and the interfaces behind authoring those agents. In this role, you will As an early and senior member of the design team, you'll work across several areas of the product and own initiatives end to end, from discovery and scoping through launch and adoption. The work often starts before the problem is defined. You'll turn ambiguity into clarity, framing the problem space before jumping to solutions, and you'll design concepts that balance vision, craft, speed, and business potential. You'll guide decisions with structured thinking and clearly articulated design rationale. We work in small, autonomous project teams where designers pair tightly with engineers and product managers. You'll interview customers, translate what you learn into the roadmap, and ship: polished new features, meaningful refinements to key flows, and along the way, build the foundational design systems that help us move faster. Fluency with AI coding tools is part design craft here. You'll prototype in Figma and in AI tools like Cursor and Claude Code, building directly on our codebase to make design ideas real enough to critique. And as a founding member of our growing design team, you'll shape our culture, hiring, and ways of working. Your background looks something like this 6+ years as a product designer, with 2+ years designing at similar scale and complexity. You've worked with complex systems, B2B SaaS, enterprise products, and worked on products where you're not the primary user. You
