Pros
Starting salaries for professionals (I.e. engineers & management) is relatively competitive if you want to avoid driving to St. Louis. However, raises are typically 2-3% (in the best of times), so don't expect much growth.
Cons
This is 3rd generation ownership that rules by arrogance, fear and intimidation. The culture is in-bred & extremely toxic and will never change unless the company is purchased & executive management is removed. It is not uncommon for the COO to belittle and yell obscenities during meetings. Manufacturing processes are old-school batch & queue and vertically integrated. No interest in lean/six sigma or any continuous improvement methodology. It's hard to believe that such a relatively small company can have such a lack of synergy.
