We are looking for an Inbound Sales Development Representative with 1+ years of customer-facing experience to join one of the fastest-growing voice AI startups and help scale our inbound pipeline engine. You'll be one of the first touchpoints for companies evaluating Retell AI, qualifying high-volume inbound leads and converting them into pipeline for our Account Executives. We've grown from $5M to $60M+ ARR in under a year with fewer than 50 people — and we need someone with a founder's mentality who thrives in chaos, moves fast, and can connect the dots with minimal instruction. This is a high-energy, high-reward role with generous compensation well above market for SDRs.
What will you be doing?
Qualifying inbound leads across website forms, email, live chat, and LinkedIn — ensuring only high-quality opportunities are routed to Account Executives
Running discovery conversations with prospects, demonstrating strong product knowledge and commercial instincts to determine fit
Scheduling and setting up qualified meetings for AEs, with compensation tied to AE-confirmed qualified calls
Partnering with revenue leadership to improve inbound qualification processes, messaging, and workflows as the team scales
Building and iterating on outreach programs, leveraging AI-forward tools to drive pipeline efficiency and quality
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.

No applications, no recruiter spam. Just the intro.
A few questions to make sure this role is the right shape for you. Two minutes.
I write the intro, send it to the founder, and handle the back-and-forth.
If they’re a yes, I book the chat. You show up — that’s the whole job-hunt.
