Pros
Real opportunities to grow into more technical roles (Control Center Operator → Systems Engineer paths exist and aren't just on paper).
You get hands-on experience with industrial systems most people only read about — OSI PI, SCADA, OMS integrations, cloud telemetry — which is hard to get elsewhere.
Management generally supports continued education and certifications.
Cons
Decisions move slowly. Getting tooling, software, or process changes approved often involves multiple layers, including approvals that flow up to the French parent company.
Procurement and IT requests can take weeks for things that would take a day at a smaller company.
Some legacy systems and processes haven't been modernized — you'll find yourself working around quirks instead of fixing them.
