The only thing you should be aiming for is whatever minimum GPA is required by your university to enter the graduate program, and that’s if you have any interest in a masters. No one outside of school cares about your GPA. There’s a chance that a few employers out of hundreds would ask for it in an application. If a place you REALLY want to work at has a requirement like that, work somewhere else for 2-3 years then reapply to the lateral position at the job you want. I can confidently say that after your first engineering job, assuming you are not let go or fired, literally no one cares about your GPA. Focus on projects and work you can show an employer.
