About the role

ABOUT RETELL AI

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 $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.

ABOUT THE ROLE

We’re looking for an Inbound Sales Development Representative to help scale and optimize Retell AI’s inbound pipeline engine.

You’ll be one of the first touchpoints for companies evaluating Retell and play a critical role in how inbound demand gets qualified, routed, and converted into pipeline. You’ll work closely with the VP of Revenue and account executives to ensure high-quality customer experiences across every inbound interaction.

This role is ideal for someone who thrives in fast-moving environments, communicates exceptionally well, and wants exposure to one of the fastest-growing AI companies in the market.

KEY RESPONSIBILITIES

  • Own timely responses across inbound channels including website forms, email, live chat, and LinkedIn
  • Qualify inbound leads and route opportunities appropriately across enterprise and SMB/mid-market segments
  • Schedule discovery and demo calls for account executives
  • Maintain clean, accurate CRM hygiene across all prospect interactions and stages
  • Develop strong product knowledge and confidently communicate Retell’s value proposition
  • Partner with revenue leadership to improve inbound qualification processes, messaging, and workflows
  • Track performance against qualified meetings, opportunities created, and pipeline contribution

YOU MIGHT THRIVE IF

  • You’re naturally high-energy and enjoy interacting with people throughout the day
  • You have prior customer-facing experience in hospitality, retail, service, support, or sales environments
  • You communicate clearly, ask thoughtful questions, and actively listen
  • You stay organized under volume and consistently follow through on details
  • You’re comfortable operating in fast-paced environments with evolving processes
  • You learn quickly and are excited to understand technical products deeply
  • You want to grow rapidly in a high-performance startup environment with meaningful ownership

JOB DETAILS

  • Cash Compensation: $6,000 – $8,000/month base (1099)
    • Variable Compensation: Performance-based bonus tied to qualified meetings and opportunities created
  • Location: Fully Remote (US or Canada)
  • Reporting Structure: Directly reports to the VP of Revenue

About Retell AI

Retell is building the AI voice layer for every business.

We’re replacing outdated call centers with real-time AI voice agents that sell, support, and retain customers at scale.

Voice is still the most natural way humans communicate, yet it’s been stuck with legacy tech for decades. We’re changing that by bringing speed, empathy, and reliability to every phone conversation.

In under two years, thousands of companies now run on Retell. We’ve grown to $35M ARR, raised a $4.7M seed, and scaled a 24-person team, backed by Y Combinator, Altman Capital, and top-tier investors.

We’re now one of the top 50 AI apps in a16z’s rankings and a top-ranking startup on the Lean AI leaderboard.

We’re moving fast, tackling hard technical problems, and setting the standard for voice automation. If you want to help define the future of how businesses talk to customers, this is the place to do it.
