Key Responsibilities

Design, develop, and deploy AI/ML/GenAI solutions for smart manufacturing use cases.

Analyze structured and unstructured industrial data (sensor data, logs, quality reports, code repositories, engineering documentation).

Build predictive models (e.g., anomaly detection, forecasting, optimization, recommendation systems).

Develop LLM-powered applications using prompt engineering, fine-tuning, and Retrieval-Augmented Generation (RAG).

Create intelligent copilots and domain-specific automation solutions.

Integrate AI systems with enterprise platforms (MES, PLM, ERP, Quality systems, Engineering tools).

Collaborate with customer stakeholders including manufacturing, quality, maintenance, and engineering teams.

Ensure scalability, reliability, explainability, and governance of AI solutions.

Participate in solution architecture discussions and PoC-to-production transitions.

Contribute to reusable frameworks and accelerators for future engagements.

Required Technical Skills
AI / ML / Data Science

Strong foundation in Machine Learning (supervised, unsupervised, time-series, anomaly detection).

Experience in Python (Pandas, NumPy, Scikit-learn, PyTorch/TensorFlow).

Feature engineering and data preprocessing expertise.

Model evaluation and performance optimization.

GenAI / LLMs

Experience working with Large Language Models (OpenAI, Llama, Azure OpenAI, etc.).

Prompt engineering and evaluation frameworks.

RAG pipeline development.

Familiarity with vector databases (FAISS, Pinecone, Chroma, etc.).

Exposure to LLM fine-tuning and guardrail mechanisms.

Engineering & Deployment

API development (FastAPI/Flask).

Cloud platforms (Azure/AWS/GCP).

Containerization (Docker) and basic DevOps/MLOps practices.

Version control (Git) and CI/CD familiarity.

 

 

Key Responsibilities

1. Develop and deploy machine learning models, predictive analytics, and AI solutions to solve business challenges.
2. Design and optimize algorithms for data processing, feature engineering, and pattern recognition.
3. Lead data exploration, mining, and visualization to uncover trends and actionable insights.
4. Collaborate with cross-functional teams to integrate data science solutions into business strategies.
