Employers like Oshkosh Corporation, Rockwell Automation, and mid-size Milwaukee-area consulting firms regularly onboard entry-level mechanical engineers into project support roles. Completing your EIT registration through the Wisconsin DSPS and developing SolidWorks or AutoCAD skills before applying gives you a measurable edge over other candidates without field experience.
