We’re hiring a Conversational AI Developer to build human-like AI phone agents that handle real conversations end-to-end: answering inbound calls, calling leads, qualifying prospects, booking appointments, and updating internal systems automatically.
This is a builder role—you’ll design voice experiences, implement call flows, integrate APIs, and continuously improve performance using real call data.

What You’ll Build
AI voice agents that can:

- Ask qualifying questions and capture structured responses
- Handle objections naturally and stay on-script
- Book appointments via calendar integrations
- Log call outcomes and update CRM records automatically
- Escalate to a human when needed with full context
Core Responsibilities
- Build and deploy voice agents using Retell AI, Vapi, Bland AI, and/or Synthflow
- Design conversation flows: greeting → intent detection → qualification → action → wrap-up
- Create and maintain agent prompts, tools/functions, memory rules, and guardrails
- Implement call routing, transfer logic, fallback behaviors, and error handling
- Integrate voice agents with business systems:
- CRMs (GoHighLevel, HubSpot, Salesforce, custom)
- Calendars (Google Calendar, Calendly, Outlook)
- Messaging (SMS/email confirmations via Twilio/SendGrid)
- Webhooks/APIs for internal tools
- Build evaluation + improvement loops:
- review call recordings/transcripts
- identify failure patterns (hallucination, bad turn-taking, wrong tool calls)
- improve prompts, flows, and data extraction
- Ensure compliance and quality:
- consent/disclosure handling (as required)
- data privacy best practices
- latency and reliability monitoring
Required Experience
- 2+ years building conversational AI (chat and/or voice)
- Hands-on experience with at least one:
- Retell AI, Vapi, Bland AI, Synthflow
- Strong prompt engineering skills for multi-turn conversations
- Practical experience with:
- tool/function calling patterns
- structured data extraction from conversations
- webhook-driven integrations
- Solid backend integration skills (one or more):
- Node.js / TypeScript, Python, REST APIs, JSON, OAuth
- Familiarity with telephony concepts:
- call flows, transfers, voicemail handling, DTMF, timeouts, retries
Nice-to-Haves
- Experience tuning ASR/TTS behavior, interruption handling, and latency reduction
- Experience with RAG / knowledge base grounding for accurate answers
- Experience with call center metrics: conversion rate, appointment rate, containment, AHT
- Familiarity with prompt testing frameworks / eval tooling
- Experience deploying on AWS/GCP (Lambda, Cloud Functions, queues, webhooks)
What Success Looks Like (First 2 Weeks)
- Ship 1–2 production-grade voice agents for a defined workflow
- Integrate end-to-end: CRM + calendar + notifications + call logging
- Establish a weekly optimization loop using real call transcripts
- Improve key metrics (booking rate, qualification accuracy, handoff quality)
Interview / Technical Challenge (example)
Candidates may be asked to:
- Design a call flow for a real scenario (inbound or outbound)
- Implement tool calls (CRM lookup, appointment booking)
- Provide prompt + fallback strategies for common objections
