I am an Undergraduate Student who landed a job as a Data Scientist. Should I pursue a PhD and can I do it while working full time? I just graduated with a computer-science bachelor’s degree and accepted a job offer as a data scientist with a well-known company. It is a research role; so I’ll presumably be working towards goals that are also academic in nature. 

Now is it possible for me to find an advisor who would be okay with me working full-time? I’ve interned for this company and they have no issues with sharing any research as long as no confidential data is involved; so I will be able to publish and share some of my work with an advisor. 

I am really enamored with the idea of having a PhD – for the sake of having a PhD (which is silly, I know). However, I’m hesitant to put my life on hold or quit my job so this is the only option left to me.
There cannot be a definite answer to your question, because we lack basic information regarding the project, arrangement etc. 

I think the best way to find out if something like that is possible is to consult your local department where you finished your BSc, the people with expertise as close as possible to your future project, who will be able to judge if this makes a valid and potentially fruitful research plan. If yes, then I do not think you will have big problems admitted to the PhD program. 

As a side note, observe that you might be asked to deal with some Master level courses/exams etc which, if you work full time, and depending how difficult is your department, will not be a piece of cake.
