Sr Product Designer

ABOUT THE ROLE

Let's build a beautiful product together

We are building infrastructure and tools that power real-time AI voice agents used by fast-growing companies. Design quality matters here—every interaction happens in real time, under pressure, with real users.

As a Product Designer, you’ll own end-to-end product design across core user workflows. You’ll work directly with founders, engineers, and customers to shape features from first principles—not just polish UI after decisions are made.

This is a high-ownership role with real influence over product direction, UX quality, and design standards.

KEY RESPONSIBILITIES

• Own the product experience end-to-end — from early concepts and PRDs to polished, shipped features used by real customers in high-stakes, real-time scenarios.

• Shape how users interact with AI voice agents, turning complex, technical workflows into clear, intuitive, and human experiences.

• Work side-by-side with engineers and founders to define, refine, and ship features, ensuring design intent and quality are preserved all the way to production.

• Be the voice of the user — conduct customer interviews, gather feedback, and translate real user pain points into thoughtful design solutions.

• Proactively raise the UX bar by identifying friction, inconsistencies, and opportunities across the product, and driving improvements from idea to launch.

• Build and evolve Retell’s design system, setting standards for consistency, scalability, and craftsmanship as the product and team grow.

• Hold a high bar for craft and quality, sweating the details and refusing to compromise on clarity, usability, or polish.

• Influence product direction through design, contributing strong opinions, clear rationale, and taste-driven decisions that shape what we build next.

YOU MIGHT THRIVE IF

• Have 5+ years of experience as a Product Designer working on shipped products.

• Have a strong user-centered design background (HCI, design, or equivalent experience).

• Have excellent product taste and a strong sense of usability, hierarchy, and visual clarity.

• Are detail-oriented and care deeply about polish and consistency.

• Enjoy working closely with engineers, PMs, and founders to shape product direction.

• Are comfortable operating in a fast-moving startup environment with ambiguity.

• Enjoy owning problems end-to-end rather than working within a narrow design scope.

• Care deeply about building products that are easy to use and delightful.
