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.
• Build reporting for key Voice AI metrics such as call volume, answer rate, connect rate, qualification rate, appointment conversion rate, transfer rate, average call duration, latency, and cost per call/minute.
• Review call recordings and transcripts to improve AI responses, latency, accuracy, objection handling, and conversion performance; run A/B tests on prompts and voices.
• Troubleshoot Voice AI, telephony, SIP, A2P, webhook, and CRM sync issues, including dropped calls, one-way audio, high latency, failed transfers, and carrier filtering.
• Support the Voice AI Onboarding & Integrations Specialist on complex custom API work and advanced agent builds for partners.
• Document agent configurations, prompts, telephony setups, A2P registrations, integrations, and troubleshooting procedures.
• Collaborate with Operations, Sales, Marketing, and client teams to turn business requirements into reliable, scalable Voice AI solutions.
• Continuously evaluate new Voice AI platforms, models, voices, and telephony features, and recommend improvements that increase automation, speed-to-lead, and margin per call.
