PECO is part of the Exelon community and does a great job in providing a diverse and accepting work environment. As an engineer there is a rotational program that encourages employees to change roles and participate in multiple aspects of the company, it is mandatory in order to raise your position.
Good learning, good benefits, and exposure to a lot of different areas of the utility. A lot of experienced engineers who've been in the industry for decades.
Cons
Large workload, small staff. Not sure since I haven't been here for long but promotions seem political. A lot of behind scenes decisions.
