Pros

Great company with supportive and talented people, an excellent work/life balance, and a positive culture. I truly enjoyed my time there and will miss it, I really loved working at this company.

Cons

Some processes and team structures could benefit from further modernization, particularly in expanding Agile adoption compared to leading IT organizations.

Pros

Fantastic place to work. Especially operations. Smart, process oriented individuals. Good pay and benefits.

Cons

Corporate can be a bit disconnected from the plant operations. But this is expected at any distributed manufacturing organization.
