Your resume is your ticket into a company. It's the first thing anyone will see of you, so be sure that it is free of errors and complete with details of your past successes. Many companies these days use software that scans resumes before they ever enter a human resources representative's hands. Study the engineering career description and use the keywords you see there in your resume. Make sure it's natural and not over done, because there's no point if it passes through the software then confuses the HR rep.
Don't be afraid to detail your experiences; potential employers want to know that you are completely capable of doing the job.
