Senior Automation Architect needed for Scalable AI Rental System (SaaS MVP)

Senior Automation Architect needed for Scalable AI Rental System (SaaS MVP) Project Overview We are an automation agency looking for a Senior Developer or AI Solutions Architect. We are building a "Business-in-a-Box" automation solution for the car rental industry. The Goal: We have a pilot client (launch customer) for whom we need to build a fully functional Minimum Viable Product (MVP). However, our long-term goal is to white-label and resell this system to other rental companies. Therefore, the architecture must be modular, scalable, and easy to deploy for new tenants. We are not looking for a simple chatbot script. We need a robust operation system. Scope of Work 1. The Backend: "Source of Truth" (Inventory Management) Our client currently has no digital infrastructure (uses manual phone/paper). We need a mobile-friendly interface for the owner to manage the fleet. Requirements: Easy upload of car photos (from phone), setting pricing rules, and managing the calendar. Logic: The system must handle availability logic, including a "Buffer Time" (e.g., auto-block car for 2 hours after return for cleaning). Tech Preference: We are open to robust Low-Code (Airtable/Softr/Glide) or Custom Code (Python/FastAPI/React), provided it is stable and cloneable. 2. The Frontend: Omni-Channel AI Agent An AI Assistant (GPT-4o based) integrated via Make.com or custom middleware. Channels: WhatsApp (Primary), Instagram, Facebook Messenger. Languages: The bot must detect and switch between Polish, Czech, and English fluently within the same conversation. Key Features: Visual Selling: When a user asks for a car, the bot fetches the specific image URL from the DB and sends it as a native image message. Function Calling: The AI must query the calendar in real-time before promising availability. Escalation: If the AI detects critical intents (e.g., "Crash", "Damage", "Police"), it must trigger a Twilio Voice Call or High-Priority SMS to the owner immediately. 3. Scalability (The SaaS Requirement) The code/scenario must not be hardcoded for this specific client. We need a "Config-based" setup where we can easily onboard Client B and Client C in the future by changing variables (Business Name, Price List, Phone Number). Project Structure (2 Phases) To ensure quality and architectural soundness, we are splitting this project into two paid milestones: Phase 1: Technical Blueprint (Paid Discovery) Deliverable: A Technical Design Document. Content: You will analyze our needs and document the exact Tech Stack, Database Schema, API Integrations, and Error Handling protocols you plan to use. Outcome: We review and approve this blueprint before development begins. Phase 2: Development & Deployment Building the approved MVP. Full implementation of the Database, AI Agent, and Twilio integrations. Handover: Full source code ownership + A "Deployment Guide" on how to clone this for our next client. Your Profile You have proven experience building complex AI Automation systems (beyond simple Q&A bots). You understand database logic (Relational databases, availability checks). You are capable of thinking in "Systems" and "SaaS" (Scalability).

How to Apply

Please answer the following questions in your proposal: Start your cover letter with the word "SCALABLE". The Tech Stack: Based on our need for a mobile-friendly inventory system + AI agent + future scalability, which specific stack would you recommend (e.g., Airtable vs Custom SQL, Make vs Python)? The Logic: How would you technically solve the "Availability Check" to ensure the AI never double-books a car? Cost Estimate: Please provide a rough estimate for the Total Project (Phase 1 + Phase 2). Apply tot his job Apply To this Job
