AI & LLM Engineer – PLOT (ODIF + OSIF)

Dear All,

Greetings from PBOplus !!

We are hiring for AI & LLM Engineer – PLOT (ODIF + OSIF)

Location: Remote / Delhi NCR
Experience: 2–5 yearsReporting To: Product Lead, PLOT AI Division

Role Overview

We are building AI copilots for manufacturing execution through our twin platforms — ODIF (On Day In Full) for human performance and OSIF (One Shift In Full) for process intelligence. You will lead the LLM and AI agent layer — transforming PLOT’s massive structured data (WBS, 3TSOP, production, and compliance datasets) into interactive, queryable AI systems using LangChain and LangGraph frameworks.

Key ResponsibilitiesFor ODIF (Human Performance AI)

· Build an LLM-based Chat Engine using RAG (Retrieval-Augmented Generation) that can answer questions about any WBS type, SOP, or job card from PLOT’s internal data.

· Develop a Quality WBS Evaluator — an AI model that scores and refines work breakdown structures based on accuracy, completeness, and compliance logic.

· Implement feedback loops that help AI improve by comparing real user inputs vs. optimal WBS models.

For OSIF (Process AI)

· Create an LLM-powered factory assistant that answers real-time questions about production status, delays, checklists, deviations, and 3TSOP adherence.

· Build context-aware retrieval pipelines using LangGraph for querying across multi-site manufacturing data.

· Collaborate with engineering teams to connect PLC/SCADA/ERP data layers to the LLM interface through secure API ingestion.

Cross-Functional

· Design vector databases (Chroma, Pinecone, FAISS) for storing and retrieving domain knowledge.

· Experiment with prompt chaining, memory management, and function calling to make the AI contextually persistent.

· Continuously improve data governance and embedding accuracy to ensure 99% factual consistency.

Required Skills

· Proven experience with LangChain, LangGraph, and RAG-based LLM systems.

· Proficiency in Python, LLM fine-tuning, and frameworks like OpenAI API, Hugging Face Transformers, LlamaIndex, or similar.

· Deep understanding of vector databases, prompt optimization, and document chunking strategies.

· Familiarity with ETL pipelines, API integration, and SQL/PostgreSQL data structures.

· Bonus: experience with manufacturing data, ERP, or process automation environments.

Preferred Background

· B.Tech/M.Tech in Computer Science, Data Science, or related discipline.

· 2–5 years of experience in applied AI, LLM development, or data intelligence systems.

· Prior work in AI agents, RAG pipelines, or domain-specific chat systems is a major plus.

Why Join

You’ll be the core AI builder in an industrial revolution — designing systems that let machines, managers, and data talk to each other. Your work will make PLOT the first platform where every SOP, checklist, and task in manufacturing becomes queryable and intelligent in real time.
