Artificial Intelligence (AI) Engineering focuses on the application of AI and Machine Learning models to solve real-world problems. It involves the development, deployment, and maintenance of AI-powered systems.

AI Engineer

1. What It Is

An AI Engineer builds and deploys AI models into production. They work with data scientists to take research models and turn them into scalable, reliable, and efficient AI applications. Key difference from Data Scientists: Focuses on deployment and engineering, not just model creation and analysis. Key difference from other engineers: Specializes in AI/ML specific technologies and challenges (model serving, scalability, performance).

2. Where It Fits in the Ecosystem

AI Engineers sit between data science and software engineering. They bridge the gap between research and production, ensuring that AI models can be integrated into real-world applications and systems.
