Job Title:

 Data Engineer (Python, Data Systems & AI Enablement)

Role Overview

Python-focused Data Engineer with strong hands-on coding skills in data-intensive systems. The role focuses on building scalable data pipelines, processing large datasets, and enabling AI/Generative AI applications through well-structured data infrastructure.

Key Responsibilities

• Build and maintain scalable data pipelines using Python
  
• Write production-grade Python code specifically for data processing, transformation, and ETL workflows
  
• Perform data cleaning, preprocessing, and feature preparation for analytics and AI use cases
  
• Use data analysis and manipulation tools to handle large datasets efficiently
  
• Develop reusable Python modules for data ingestion and pipeline automation
  
• Perform exploratory data analysis (EDA) to understand data patterns and quality issues
  
• Optimize data workflows for performance, scalability, and reliability
  
• Support data requirements for AI/ML and Generative AI systems
  
• Build data services and APIs to support downstream AI applications
  
• Ensure data quality, consistency, and observability across pipelines
  

Required Python & Data Libraries (Hands-on Experience Mandatory)

Candidates must have strong practical experience with:

• pandas — data manipulation, transformation, and analysis
  
• NumPy — numerical operations and array-based processing
  
• Matplotlib — data visualization and reporting
  
• scikit-learn — basic ML workflows and model evaluation
  
• PyTorch — deep learning and AI model experimentation
  

AI / Generative AI Enablement

• Prepare and structure datasets for ML and LLM-based systems
  
• Support integration of AI models into data pipelines and applications
  
• Enable workflows for Generative AI use cases (RAG systems, agent workflows)
  
• Work with multiple AI model providers:
  
• OpenAI
  
• Anthropic
  
• LLaMA
  
• Mistral
  
• Exposure to AI orchestration frameworks such as LangChain, AutoGen, and CrewAI
  

Core Requirements

• Strong hands-on Python coding expertise focused on data systems (critical requirement)
  
• Ability to write clean, efficient, production-grade Python code
  
• Strong understanding of data structures, ETL pipelines, and data workflows
  
• Experience working with large-scale structured and unstructured data
  
• Strong SQL skills for data extraction and manipulation
  
• Understanding of data modeling and analytics workflows
  
• Ability to support end-to-end data-to-AI pipelines
  

Preferred / Good to Have

• Experience with big data or distributed processing systems
  
• Understanding of vector databases and embedding-based retrieval systems
  
• Experience building APIs or services for data/AI systems
  
• Familiarity with cloud platforms (AWS, Azure, GCP)
  
• Exposure to production monitoring and data observability tools
  

What Success Looks Like

• High-quality Python code powering scalable data pipelines
  
• Reliable, clean, and well-structured datasets for AI systems
  
• Efficient ETL workflows with minimal manual intervention
  
• Seamless support for ML and GenAI applications in production
