Masters in CS or Coding Bootcamp?

I’m a chemical engineer looking into changing careers. I need some direction if to do a Masters in CS/SWE or Coding Bootcamp? At the end of this, I would like to join a big tech company. In my industry, I’ve worked for the biggest players (BASF, Dow Chemical, Unilever [in Supply Chain]), so I have high expectations of myself to get into the biggest players in Tech.

Also, right now I have a full time job that I’m not really willing to leave unless the response is overwhelming to do a coding bootcamp.

For Online Master’s program I would do something like Georgia Tech, USC, University of Illinois, etc.

To be clear, I’m changing careers because coding is a passion of mine and all my internships and current role I’ve found solution by coding and making this easier. Not because Tech is hot right now.

What would be the best way to establish a good CS/SWE background and get a good SWE job at a big company?
