Pros
Very work process oriented, especially in bigger sites in the Gulf Coast. Mileage will vary with smaller parts of the business (lots of red tape in bigger sites but small sites you can have a lot of independence and ownership). Lots of good folks/mentors via an internal SME network in the EE space that are willing to help, very good culture amongst the engineers. Incentivized to learn and contribute to technical development on top of your job responsibilities. If you're willing, there's more learning and work... but that comes with the cons too. In the smaller sites you can have a lot of freedom (with the right leader) to run your own projects and make changes. Great for learning on the fly, under duress, and stacking up your resume for the next role. Benefits are good and so can work-life balance be depending on where you are.
Cons
Company is shifting away from non-core related manufacturing and putting up assets that used to be company owned for immediate cash flow (coincidentally, the most interesting places to work at as an EE). Some of the SME networks that exist internally may be offloaded as well in the next few years. Struggling heavily with the market with China and PE, reflected in lots of EEs are leaving and transitioning elsewhere (or retiring). Lots of brain drain happening and company has terrible EE retention due to lack of opportunities (bloated if in design, not enough projects) and struggling pay. In the projects that do happen a lot of the design is basically outsourced internationally for cost saving measures, that ironically end up costing more a lot of the time due to rework since a lot of the resources overseas just aren't capable. They will overwork and lowball you if given the chance. Very confident in their work process that they're willing to let talent go (to the detriment of literally everyone else in the company). In the next 5-10 years it will be a struggle in the electrical space. It's a chemical manufacturing company, remember, and headed towards a downturn in the cycle. Screwed up in putting tons of a capital on a project in Canada that may never pan out like the ME venture in Sadara years ago.
