Full Job Description
ABOUT RETELL AI Retell AI is using the 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 $36M ARR with a team of 20 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. - We’re a top 50 AI app in a16z list: https://tinyurl.com/5853dt2x - #4 on Brex's Fast-Growing Software Vendors of 2025: https://www.brex.com/journal/brex-benchmark-december-2025 - We're also one of the top ranking startups on: https://leanaileaderboard.com/ - Enterprise tech 30: https://www.wing.vc/et30/overview ABOUT THE ROLE 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.
