Are you familiar with computer engineering?
No but my daughter is a software engineer.
That's awesome.  Computer engineers integrate several fields of electrical engineering and computer science.  They develop computer hardware and software (like your daughter).
Please tell me the differences between system engineering and software engineering.
Computer engineering
Computer engineering is a branch of engineering that integrates several fields of computer science and electronic engineering required to develop computer hardware and software. Computer engineers usually have training in electronic engineering (or electrical engineering), software design, and hardware-software integration instead of only software engineering or electronic engineering. Computer engineers are involved in many hardware and software aspects of computing, from the design of individual microcontrollers, microprocessors, personal computers, and supercomputers, to circuit design. This field of engineering not only focuses on "
