How to Prepare for the Recruiting Process -

📢 Why Are They Hiring an AI Automation Engineer (Voice AI & Middleware Integration)? 🏢

Our client is hiring an AI Automation Engineer to bring all technical development, deployment, and fulfillment fully in-house, replacing a third-party agency that currently handles it. You'll build and own the custom middleware that connects AI voice platforms (Vapi, Retell, Assistable within GoHighLevel) to field service management systems like ServiceTitan and Housecall Pro, so live phone conversations turn into accurate, booked jobs on a contractor's dispatch board. Beyond the build, your mission is reliability: proactively testing and monitoring voice agents so contractors get zero downtime and high booking accuracy, documenting the systems in clear SOPs, and laying the technical groundwork for upcoming enterprise industry partnerships in 2027. This is a hands-on, high-ownership role where you'll work directly with the founder and grow into technical leadership as the team expands.

If you're a proactive, code-first engineer who loves building voice agents and integrations that actually work in the real world, and you take pride in systems that never miss a call—this role could be a great fit for you. ✨

✅ Qualifications:

Must-Haves:

• 🎙️ Voice AI Agent Experience– Hands-on experience building and deploying production voice agents with Vapi, Retell, Assistable, and/or ElevenLabs, including prompt tuning, latency optimization, and knowledge base design.
• 💻 Real Coding Skills– Strong JavaScript and/or TypeScript; you write, review, and debug your own code (no "vibe coding"). Comfort reading .NET / C# / C++ environments is a big plus.
• 🔌 APIs, Middleware & Integrations– Proven experience building middleware and integrations using REST APIs, OAuth, webhooks, and SDKs.
• ⚙️ GoHighLevel Expertise– Solid experience building workflows, automations, and sub-account setups in GoHighLevel (GHL).
• 🤖 Automation & Agent Frameworks– Experience with n8n, Hermes Agents, Composio, OpenClaw, or similar automation and agentic AI platforms.
• 🔐 Security-Minded– Solid grasp of API security, data privacy, credential vaults, VPNs, and VPS hosting.
• 💬 Clear Communication & Ownership– Fluent written and spoken English, comfortable supporting clients directly, and able to work independently without constant supervision.

Nice-to-Haves:

• 🏠 Field Service Management Experience– Direct experience with ServiceTitan or Housecall Pro, or with home service trades (HVAC, plumbing, electrical).
• 🧠 Advanced AI Concepts– Familiarity with RAG, MCP, and vector databases.
• 🌐 Web & Marketing Tech– Website builders, hosting, landing pages, Google Business Profile, and AEO/SEO automation.
• 🧑‍💻 Software Engineering Background– Software engineers or full-stack developers who have moved into AI automation and voice agents are an ideal match.

Responsibilities of the AI Automation Engineer (Voice AI & Middleware Integration):

Your responsibilities include:

🔌 Middleware & Field Service Platform Integrations

• Build and maintain custom middleware connecting AI voice platforms (Vapi, Retell, Assistable within GoHighLevel) to Field Service Management (FSM) systems
• Integrate with platforms like ServiceTitan and Housecall Pro using REST APIs and OAuth
• Write integration logic that interfaces with .NET / C# / C++ backend environments
• Program and verify end-to-end booking workflows that move live voice conversations straight into contractor dispatch schedules
• Monitor, diagnose, and resolve sync issues such as duplicate bookings, dropped data payloads, or failed scheduling attempts
• Code, review, and debug custom application logic in JavaScript and/or TypeScript

🎙️ Voice AI Agent Engineering & Tuning

• Build, configure, and maintain production-grade voice agents using Vapi, Retell, Assistable, and ElevenLabs
• Fine-tune latency, test prompt frameworks, design agent harnesses, and curate dynamic knowledge bases
• Architect multi-step decision trees and parent-child logic (e.g., distinguishing a tenant from a commercial property manager during an emergency call)
• Run automated tests on conversational accuracy, speech recognition, and intent categorization to catch bugs before clients do
• Keep after-hours call answering and emergency dispatch agents running reliably

⚙️ Omnichannel & Back-Office Automation

• Build and manage GoHighLevel workflows across SMS, email, appointment reminders, and estimate follow-up campaigns
• Implement automations using platforms such as Hermes, OpenClaw, Composio, and n8n
• Build AI agents that securely log into third-party portals to complete repetitive contractor admin tasks
• Help build, test, and deploy company-wide automation packages for beta client accounts

🤝 Client Onboarding & Technical Support

• Join technical onboarding calls with new clients to gather system requirements, parameters, and integration details
• Execute full client setup and integration during a typical two-month implementation window
• Connect client information to their respective GoHighLevel sub-accounts
• Proactively verify that client systems, credentials, and automations stay active, secure, and up to date
• Handle technical support and troubleshooting when clients report issues
• Escalate and resolve platform bugs directly with SaaS vendor support teams (including GoHighLevel)
• Build client-facing and internal dashboards tracking voice minutes, booking volume, and system activity

📋 Internal Operations, Process Automation & SOPs

• Configure internal GoHighLevel automations (e.g., sending service agreements after payment, kicking off projects when documents are signed)
• Document technical architectures and create SOPs for internal team execution
• Recommend technical solutions and collaborate with the founder on system design
• Work alongside the current fulfillment agency during a short overlap period to absorb existing workflows and system logic before taking full ownership

🔐 Data Security & Credential Management

• Enforce data privacy, API security, and protection protocols for client records and backend integrations
• Manage and share sensitive credentials securely using tools like LastPass, NordPass, or One-Time Secret
• Work through designated secure environments and VPN platforms

🌐 Secondary Technical & Marketing Projects (Nice-to-Have)

• Assist with website setup, landing pages, and hosting configurations as needed
• Implement Answer Engine Optimization (AEO) and automated AI content workflows
