About the role

What we're looking for:

We need someone with 5+ years of experience as a designer who has strong Figma skills and hands-on HTML/CSS experience. You should be a design-first person who can bridge the gap between creative and engineering teams, with a track record of building or contributing to design systems at real products. Bonus points if you have experience at a SaaS or AI company and have shipped 0-to-1 products.

What you'll do:

Build Retell's design system from scratch: component library, design tokens, Figma variables, and Storybook documentation
Take ownership of design-code parity across Retell's core product surfaces (dashboard, agent config, CRM views)
Work closely with the CPO, product managers, senior product designer, and engineering team to raise the quality bar on every product surface
Translate Figma designs into production-grade components with pixel-level accuracy using AI-first workflows (Cursor, Claude Code)
Prototype in code and test with real users before full systemization
Review frontend PRs for visual quality and maintain visual consistency at scale
Document and share AI-native prompts and workflows with the design and engineering team

Key context for recruiters:

This is a designer who codes, NOT an engineer who designs. Lead with the creative/design side when sourcing and pitching.
Strong Figma skills and HTML/CSS experience are non-negotiable. React and TypeScript are listed in the JD but per the hiring team, they are not hard requirements — HTML/CSS is what matters most.
Portfolio will be evaluated by the hiring manager and is critical to advancing past the initial screen. Ensure candidates have a portfolio to share.
Target titles: Design Engineer, Web Designer, UX/UI Designer, Interaction Designer, Product Designer (with coding experience), UI Engineer
Target companies: Meta, Amazon, Shopify, 11 Labs, AI startups, design-forward SaaS companies

Retell AI is using first principles to reimagine the call center with cutting-edge voice AI.

Thousands of companies now utilize Retell’s AI voice agents to handle sales, support, and logistics calls that once required large teams of human agents. Backed by Y Combinator, Alt Capital, and other leading investors, we have scaled to $60M ARR with a team of 40 people, up from $5M at the start of 2025.

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.
