Job description
Full-time
On-site
San Francisco Bay Area
Retell AI is using first principles to reimagine the call center with cutting-edge voice AI.
Since launching 18 months ago, 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.

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.

- 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
