I would also add that a BEng or MEng without any industrial experience is somewhat comparable to a fATPL with 250h. So, be realistic about what sort of engineering work you think you may be able to find, should you ever end up in a situation where you wish to use it. As with flying skills, engineering skills are lost quickly without practice and most potential employers will bear this in mind if the candidate has limited professional development. Focus on the transferable skills when looking for such work rather than the technical skills.
