ABOUT [REDACTED]

[REDACTED] is using first-principles thinking to reimagine the call center with cutting-edge voice AI. Thousands of companies now use [REDACTED]’s AI voice agents to handle sales, support, and logistics calls that once required large teams of human agents. Backed by [REDACTED], [REDACTED], and other leading investors, we’ve scaled to $80M in ARR with a team of 50, up from $5M at the start of 2025, and are now valued at over $1.5B.

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 act as frontline agents, QA analysts, and managers, continuously executing, monitoring, and improving every customer interaction.

We’re growing fast and looking for ambitious builders who want to tackle hard technical problems, move quickly, and have a real impact on one of the fastest-growing voice AI companies in the world.

Let’s build the future together.

ABOUT THE ROLE

Let’s build a beautiful product for [REDACTED].

[REDACTED] is building infrastructure and tools that power real-time AI voice agents used by fast-growing companies. We care deeply about making complex, technical workflows feel clear, intuitive, and thoughtfully designed.

As a Product Designer Intern at [REDACTED], you’ll work closely with our designer, engineers, and founders to bring product ideas to life. You’ll take ownership of scoped design projects, moving from early explorations and prototypes to polished experiences that reach real customers.

This is a hands-on opportunity to develop your product thinking, strengthen your visual craft, and learn how great design gets shipped, with guidance and feedback from the team.

KEY RESPONSIBILITIES

• Design user flows and interfaces for building, testing, and managing AI voice agents, making complex interactions easier to understand and navigate.
• Take scoped projects from initial concepts and wireframes to polished designs, incorporating feedback along the way.
• Create interactive prototypes in [REDACTED] to communicate ideas, explore alternatives, and refine interactions.
• Work side-by-side with engineers to ship features, clarify edge cases, and ensure the finished experience reflects the design.
• Identify UX friction and visual inconsistencies, and propose thoughtful, practical improvements.
• Contribute reusable components, patterns, and documentation to [REDACTED]’s design system.
• Hold a high bar for craft, paying attention to typography, spacing, hierarchy, interaction states, and consistency.

YOU MIGHT THRIVE IF

• You’re a current student or recent graduate in design, HCI, or a related field, or have equivalent practical experience.
• You have a portfolio that demonstrates product thinking, visual craft, and clear design decisions. Class projects, personal projects, and previous internship work all count.
• You’re comfortable using [REDACTED] to create interfaces, reusable components, and interactive prototypes.
• You have a strong sense of usability, hierarchy, and visual clarity.
• You’re detail-oriented and care deeply about polish and consistency.

• You’re excited about AI and enjoy collaborating closely with designers, engineers, and founders.

Why [REDACTED]?

• Work directly with the founders and product team.
• Get a front-row seat to how one of the fastest-growing AI infrastructure startups builds products.
• Own meaningful projects from day one, not busy work.
• Learn how world-class AI products are launched, documented, and continuously improved.
