Firmware vs Frontend/Backend

Hi all,
Currently I'm interning (for 6 months) at Western Digital and have a full time offer for Senior Firmware Developer which shall start from July 2022.
The work is a little hectic and i sincerely do not enjoy this and thinking of interviewing for SDE roles as those interest me more.
Is it okay to leave the company just after joining? What are the bad merits it will leave on my resume?
