What is expected from new grad AI engineers?

I’m a stats/ds student aiming to become an AI engineer after graduation. I’ve been doing projects: deep learning, LLM fine-tuning, langgraph agents with tools, and RAG systems. My work is in Python, with a couple of projects written in modular code deployed via Docker and FastAPI on huggingface spaces.

But not being a CS student i am not sure what i am missing:

- Do i have to know design patterns/gang of 4? I know oop though

- What do i have to know of software architectures?

- What do i need to know of operating systems?

- And what about system design? Is knowing the RAG components and how agents work enough or do i need traditional system design?

I mean in general what am i expected to know for AI eng new grad roles?

Also i have a couple of DS internships.
