It depends on your role there.
Big factories can be rewarding or miserable just like any other place. Manufacturing has many opportunities for an EE.
As a design engineer, you could design the electrical portions of the products and the controls that hydroman mentioned.
As a manufacturing engineer, you could be the process procedure person, the troubleshooting person, the electrical designer for new production equipment or expansion, or other functions.
If the plant is big, they might need a facility engineer. Those posts often go to EEs, but also MEs.
There are safety engineers, too. Inspect, report, inspect, report. Incident? Investigate, inspect, report.
They might need a compliance engineer. Make sure the product meets UL, gets CE, keeps records organized, deals with code issues and product liability.
In any of those entry-level cases, your first goal should be to work your way into engineering management. Then you can make PowerPoint presentations and attend meetings all day. The donuts are delicious.
Next, you should aim at plant engineer, director of engineering, or another top-level job in which somebody else makes all the PowerPoint shows for you before you attend the meetings. Executive-level meetings have much better donuts, and usually some mixed nuts and Halloween-size candy bars.
Finally, try to achieve chief engineer status. They'll only come to you for troubles that nobody else has been able to solve, or when there is disagreement between design and manufacturing. You'll also be available for engineering safety and ethical issues. The rest of your time is yours to decide. Pick your own projects to enhance efficiency, reliability, safety, or cost control. Make your own priorities. Write an occasional memo when needed to get buy-in and funding from the plant manager. Bask in the respect that you've earned.
Best to you,
Goober Dave
