Primary Task
- Design, build, configure, and maintain Voice AI agents on platforms such as Vapi, Retell AI, Bland, Synthflow, and GoHighLevel (GHL) Voice AI for inbound and outbound calling.
- Join sales and client calls to scope Voice AI builds, run live demos, map call flows, and estimate per-minute costs.
- Develop conversational agents that handle lead qualification, appointment setting, follow-ups, customer support, call routing, warm transfers, and reactivation campaigns, etc.
- Write and optimize system prompts, conversation flows, tool/function calls, objection-handling logic, fallback responses, and human escalation paths so calls sound natural and convert.
- Select and tune the voice stack: LLM (OpenAI, Anthropic, etc.), speech-to-text (Deepgram, etc.), text-to-speech (ElevenLabs, Cartesia, PlayHT, etc.), voices, interruption sensitivity, endpointing, and latency settings.
- Configure and manage telephony, including Twilio, Telnyx, Vonage, and SIP trunks; phone number provisioning and porting; inbound/outbound routing; call forwarding; voicemail detection; and transfers to live agents.
- Own A2P 10DLC registration and compliance, including Brand and Campaign registration, use-case selection, sample messages, opt-in/opt-out flows, carrier vetting, and resolving rejected or suspended campaigns.
- Manage caller reputation and deliverability: STIR/SHAKEN attestation, CNAM/branded caller ID, spam-likely flag remediation, number rotation, and toll-free verification.
- Ensure calling and texting comply with TCPA, call-recording consent rules, DNC lists, calling-hour restrictions, and state-specific AI disclosure requirements.
- Integrate Voice AI agents with CRMs (GHL, HubSpot, Salesforce), calendars, and external systems through APIs, webhooks, Zapier, Make, n8n, and custom integrations.
- Build automations that update CRM records from call outcomes, including disposition, lead status, appointment status, call summary, transcript, tags, and follow-up tasks.
