About the Project

-------------------------------------------------------------------------------------------------

AskPeriyar.ai is building a multilingual (Tamil + English) AI chatbot designed to emulate the writings, ideology, and tone of Periyar using retrieval-augmented generation (RAG). This project requires building a highly accurate, authentic, and scalable AI system integrated directly into a WordPress environment.

The chatbot must answer user queries strictly based on Periyar’s verified corpus, with proper source citations, age-appropriate explanations, and a consistent reformist tone.

Role Overview

-------------------------------------------------------------------------------------------------

We are seeking a skilled AI Developer with strong experience in RAG systems, WordPress AI plugins (AI Power), OpenAI API integrations, and vector database pipelines.

You will lead the full AI implementation lifecycle — from document preprocessing to embeddings, Pinecone indexing, retrieval, orchestration, WordPress integration, and ongoing optimization.

Key Responsibilities

1️⃣ WordPress + AI Power Implementation

• Install and configure the AI Power Pack plugin in WordPress.
• Connect OpenAI API keys and configure the AskPeriyar assistant.

• Prepare a structured document pipeline for embeddings.

3️⃣ Embeddings & Pinecone Indexing

• Generate embeddings with OpenAI (text-embedding-3-large).
• Build and maintain Pinecone vector indexes segmented by language.

4️⃣ Retrieval-Augmented Generation (RAG)

• Implement top-k search, reranking, and context assembly.
• Ensure the chatbot answers strictly from authorized corpus.

5️⃣ Backend Integration

• Build backend orchestration between WordPress, Pinecone, and OpenAI.
• Ensure secure API handling, logging, and fast response times (≤3 seconds).

6️⃣ Evaluation, Monitoring & Scaling

• Implement evaluation metrics (RAGAS or similar).
• Set up continuous monitoring, improvements, and data refresh processes.

• Expertise in Pinecone or similar vector DBs.
