GoHighLevel (GHL) + Make.com + AI Voice (Retell) Automation Developer

Time Commitment: 20-40 hours per week

Duration & Project Structure:
- 1-week initial engagement to build a barebones demo for client review.
- If approved, the work continues for an additional 6–8 weeks to complete full implementation. A video interview will be required at this stage.
- If things go well, this could lead to additional or ongoing work beyond this project.
- Work is delivered in weekly sprints using an agile workflow.

This job is for you if:
- You’re comfortable working iteratively, shipping weekly, reviewing logs, fixing issues, and making sure things actually work in the real world, not just on paper.
- You like building, connecting tools, testing edge cases, and sticking with problems until they’re fully solved.
- You can be given the required inputs, and outputs for a system and take responsibility for building the internals of the system end to end without micromanagement.
- You can communicate clearly in writing, ask good questions when requirements are unclear, and give updates without needing constant follow-ups.

The Project
We are migrating a law firm’s CRM and sales system to a high-velocity, high-automation stack. We have a defined project roadmap, and architectural plan. We need a skilled Automation Developer to execute the build, wire up the APIs, develop end-to-end conversational AI prompts and ensure the data flows flawlessly.
 
Your job is to build this system, test it, and make it bulletproof. We’ll work in phases, shipping updates weekly and iterating as we go.
 
The Tech Stack (Must Have Experience)
- HighLevel (GHL): Deep understanding of Workflows, Custom Values, Pipelines, Conditional Logic and Webhooks.
- Make.com: Advanced scenario building (JSON parsing, Webhooks, Error Handlers, Routers, Array Aggregators).
- API Integrations: Experience connecting REST APIs. RingCentral will be a key app to integrate via Make as well as function/tool calls with Retell AI.
- Retell AI (or similar): Experience with AI Voice agents is a major plus.
- AI/LLM APIs: Using OpenAI, Claude & Gemini APIs via Make to develop custom conversational agents and classification systems.
- Legal Tech: Experience with Clio Manage/Grow or RingCentral is a massive bonus.
- Microsoft Office APIs & Automations: Integrating M365 apps, OneDrive & SharePoint with other apps using - Make.com modules and simple PowerAutomate workflows.
- Other apps: There will be other apps to integrate as well, but if you're comfortable with the above, others shouldn't be an issue.
 
Core Responsibilities
- GHL Workflow Logic: Build complex intake workflows in HighLevel without creating infinite webhook loops.
- Make.com Scenarios: Build scenarios to sync data between GHL, Clio Manage, and Smartsheet.
- Telephony Routing: Assist in prompt development and configuring Retell AI to route calls based on logic (e.g., checking staff availability via RingCentral API).
- Snapshot Creation: Ability to package the build into a GHL Snapshot for future deployment.
- Hyper-Care Support: Monitor execution logs during "Go-Live" to catch and fix bugs immediately.
 
Logistics
- Agile Workflow: We work in weekly sprints. You will receive clear Initiatives and User Stories. You'll be responsible for breaking this down into tasks to be implemented.
- Communication: Asynchronous is fine, but some overlap with Atlantic Standard Time (AST) (Morning/Early Afternoon) is preferred for live testing.
- Data Privacy: You will be handling sensitive data; discretion and adherence to security protocols are mandatory. NDA is required.
 
Screening Questions (Mandatory - Add answers in your proposal)
- To ensure you are a fit for this technical stack, please answer the following 4 questions. Proposals without these answers will be ignored.
- The Loop Problem: We are syncing data bi-directionally between HighLevel, RingCentral and other apps using Webhooks. How do you structure your Make.com scenarios and GHL workflows to prevent an infinite loop of updates?
- The Sync Problem: We need to sync Contact updates between Clio Manage, RingCentral and HighLevel. If a phone number is updated in both systems at the exact same time, how would you handle the conflict resolution in Make.com?
- Tuning AI Agents: How would you go about designing AI conversational agents (voice and chat) so that they can handle a variety of edge cases and complex scenarios while making them production ready?
- Availability: This project requires a fast turnaround for an MVP demo. Are you available to start immediately and are you able to commit 20-40 hours per week?
