It is important to show not only work experience, but also specific achievements. For example, process optimization should be supported by numbers: how much time or money was saved thanks to your decisions. I recommend checking out a useful resource that has templates and recommendations for an industrial engineer resume: https://engineernow.org/post/industrial-engineer-resume-templates-examples-and-tips/13 . It describes in detail how to structure a resume and what key points to highlight. For example, important sections: experience, certifications, software skills (AutoCAD, Lean, Six Sigma, etc.). Employers like to see results. The main thing is to focus on your achievements and specific numbers.
