Role Description

This is a full-time, on-site role located in Bengaluru for an Artificial Intelligence Engineer. The AI Engineer will design, build, and deploy AI-driven applications that combine machine learning, large language models (LLMs), embeddings, and retrieval-based intelligence using modern tools such as LangChain, FAISS, and FastAPI. The position requires expertise in software development and hands-on implementation of AI technologies to meet project goals. AI Engineer need to work alongside a talented team of software engineers to turn AI research and concepts into scalable, production-ready systems that enhance automation, decision-making, and user experience.

Detail Job Responsibilities

Design and Develop AI Systems :

Implement scalable AI services using FastAPI and LangChain , integrating LLMs (OpenAI, HuggingFace, Anthropic, etc.) into production environments.

Build Embedding Pipelines :

Create and optimise text and document embedding workflows using HuggingFace sentence-transformers and FAISS for semantic search and vector retrieval.

Data Processing & Ingestion :

Develop ETL pipelines to process structured and unstructured data (CSV, JSON, PDF, text), ensuring quality and consistency for model consumption.

RAG (Retrieval-Augmented Generation) :

Design retrieval-based AI agents that combine contextual data with model reasoning for accurate and explainable responses.

Prompt Engineering & Orchestration :

Create and refine prompts, system templates, and a few short examples to improve LLM responses and prevent hallucinations.

Database Interaction :

Use SQLAlchemy ORM to interact securely with relational databases and manage schema-based contextual data retrieval.

Testing and Validation :

Write unit and integration tests (pytest) for API endpoints, embeddings, and AI pipelines to ensure system reliability.

Skills Requirements

Educational Background :

Bachelor's or Master's degree in Computer Science, Artificial Intelligence, Data Science, or a related quantitative field.

Programming Proficiency :

Strong skills in Python are required, including OOP, async / await, and modular programming.

AI / ML Core Knowledge :

Understanding of machine learning algorithms , transformer-based models , NLP , and vector embeddings .

Frameworks & Tools :

LangChain or LlamaIndex (LLM integration frameworks)

FastAPI (for API development)

HuggingFace Transformers / SentenceTransformers (for embeddings)

FAISS / Chroma (for vector database and similarity search)

Any Relational database knowledge is required

Good To Have :

Experience with OpenAI API , Anthropic Claude , or Gemini .

Familiarity with Docker , Git , pytest , and CI / CD pipelines .

Knowledge of data visualisation tools (Streamlit, Gradio, Plotly).

Exposure to deep learning using PyTorch or TensorFlow.

Soft Skills
