Job Description

The client seeks a self-directed

Conversational AI Engineer

to build an end-to-end WhatsApp-based AI concierge platform for the tourism industry. This role requires a hands-on builder capable of owning the entire development lifecycle--from architecture to deployment--while collaborating with a non-technical founder.

This is a unique opportunity to lead the technical execution of a greenfield product that combines curated content with advanced conversational AI to deliver real-time support to travellers via WhatsApp.

Key Responsibilities

Design and develop a fully functional MVP from the ground up. Work independently with minimal technical guidance, while communicating clearly with a non-technical founder. Integrate WhatsApp Business API via Whapi, Twilio, or 360Dialog. Build a Retrieval-Augmented Generation (RAG) pipeline using LangChain, LlamaIndex, and OpenAI GPT-4o. Ingest and structure content from a CMS and web-scraped sources via REST or Webhooks. Store and manage chat history and user metadata using PostgreSQL. Implement monitoring tools, unit and integration tests to ensure product reliability. Document deployment, infrastructure, and maintenance steps for ongoing support.

Required Skills & Experience

3+ years of experience building production-grade chatbots or conversational AI systems. Proven ability to take projects from idea to deployment independently. Strong backend development skills using Python or TypeScript/Node.js. Hands-on experience with WhatsApp Business API platforms (Whapi, Twilio, or 360Dialog). Practical knowledge of LLM-based RAG architectures and vector databases (e.g., Supabase, Pinecone, Weaviate). Experience integrating with RESTful and/or GraphQL CMS systems. Familiarity with GDPR-compliant practices for PII and consent flows. Ability to communicate progress and challenges clearly to non-technical stakeholders.

Nice to Have

Experience with Klaviyo API or Meta Messenger API.
