Senior Product Designer [33344]

Our vision for 2026 is to build a modern CX platform where entire contact centers are powered by AI. Instead of basic automation that needs constant human tuning, we’re creating intelligent AI “workers” that can act as frontline agents, QA analysts, and managers - continuously executing, monitoring, and improving customer interactions. We’re growing quickly and looking for ambitious builders who want to tackle hard technical problems, move fast, and have real impact at one of the fastest-growing voice AI startups. Let’s build the future together.

ABOUT THE ROLE

Let's build a beautiful product. The company is 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 company'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.
