Where do Computer Engineering/Science differ

I'm currently a sophomore CS major(a semester behind because I decided I hated chemistry and was only doing pharmacy for money) and still unsure of where I should be in terms of focus. My interest is primarily in low level software like Operating Systems and embedded systems. Am I right in choosing to pursue a CS degree? I have no interest in hardware and my ideal job would be writing low level software for embedded devices like cell phones or consoles. If CS isn't the ideal choice how far off is it? Is someone with a masters degree in CS able to jump into an embedded systems job depending on the focus?

Op here,

curriculum includes the classes: Discrete Structures, Operating Systems, Computer Organization and Assembly, Principles of Programming Languages, Software Design and Development, Data Structures, and Algorithms.

Then I have to take 2 classes in electives where I can do: Compiler Design, Principles of Computer Security, Software Engineering, Automata Theory, Numerical Computations, Symbolic Computation, Database Management Systems, AI, Computer Networks, and Distributed Processing.

and 3 more electives that can either be from the previous or(I've selected the seemingly most relevant of senior level classes): Compiler Design, OOP Languages and Systems, Data Visualization, Design and Analysis of Algorithms, Cryptology, Software Engineering, (Applied, Numerical, Symbolic, or Quantum) Computation, Mobile Telephony Communications, or Intro to Machine Learning.
