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.
