Design Engineer

Design Engineer

Retell AI transforms customer experience with voice AI for enterprises, including customers like CVS/Aetna, American Airlines, Lenovo, and Grab. We have more customer stories than we can tell!

Retell is hiring a Design Engineer to own the bridge between design and code.

You will build and maintain our design system, prototype in code, implement UI primitives, and ensure that what ships looks exactly like what was designed. AI tools are a first-class part of how you work, not a side experiment. You will collaborate closely with our product designer and work across the engineering team to raise the quality bar on every product surface.

This is a role for someone who cares as much about the craft as the output. You ship real components to a real product used by thousands of companies running AI voice agents at scale.

Key Responsibilities

• Work AI-first: use Cursor and Claude Code as your starting point for component work, with your own judgment refining quality
• Build and own the Retell design system: component library, Storybook, design tokens, and Figma variables
• Prototype in React and TypeScript and test with real users before full systemization
• Translate Figma designs into production-grade components with pixel-level accuracy
• Own design-code parity across Retell's core product: dashboard, agent config, CRM views
• Review frontend PRs for visual quality, not just functionality
• Document and share AI-native prompts and workflows with the design and engineering team
• Partner with the product designer to evolve the visual language as the product scales

You Might Thrive If

• You have built or significantly contributed to a design system at a real product
• You are fluent in Figma and know how to maintain a component library at scale
• You write clean React + TypeScript and care about component API design
• You actively use Cursor, Claude Code, or similar tools and have clear opinions on how to get good output
• You prototype in code rather than waiting for pixel-perfect specs
• You notice when spacing is off and can't leave it alone
• Designers and engineers both love working with you
• You thrive in fast-moving products where specs evolve mid-build

What We Are Looking For

Must Have

• Strong Figma skills: component library, variables, auto layout
• Solid frontend: HTML, CSS, React, TypeScript
• Experience building and maintaining UI component libraries
• Design systems knowledge: tokens, spacing, visual consistency at scale
• Active use of AI coding tools with clear opinions on where they help and where they don't
• Has shipped real components to production products

Nice to Have

• Experience with Storybook
• Motion and interaction design sensibility
• Familiarity with accessibility standards
• Background at a design-forward SaaS company
• Interest in mentoring others on AI-native workflows

How We Evaluate

We care less about where you went to school and more about:

• Whether you have actually owned a design system, not just contributed to one
• Whether your components are clean, reusable, and visually accurate
• Whether you use AI tools fluently and can show us how
• Whether designers and engineers both want to work with you
• Whether you sweat the details that make products feel polished
