🔄 Understanding AI Roles: The Overlap Challenge

Before diving into specific roles, it’s important to understand that job titles in AI often overlap across different companies.

Why Does This Happen?

Different organizations define roles differently based on their requirements and understanding:

  • Company A might call someone an “AI/ML Engineer”
  • Company B might call the same role a “Data Scientist”
  • Both could be building machine learning models

Key Takeaway: Don’t focus too much on job titles. Instead, pay attention to:

  • ✅ What work the role actually involves
  • ✅ What skills are expected
  • ✅ What technologies you’ll work with

🤖 AI Engineer / ML Engineer / Gen AI Engineer

What Do They Do?

AI Engineers are responsible for developing AI-based systems and algorithms for companies. They build machine learning and deep learning models and deploy them to production, integrating AI into existing products or services.
