I have been working at Opower full-time - Professional Services Engineer Opower Employee Review

Everyone was friendly to work with. Surprisingly well run as a company.

Not sure how their culture has changed after being acquired by Oracle. Betting it was for the worse.

Every day at Opower was inspiring - the people are smart, new ideas are always being brought to the table, and everyone is motivated to do their best work because the company is doing good things for the world. People take each other seriously at work but also have so much in common that you end up with many friends outside of the office, and those relationships range across all levels - I count my old manager as one of my closest friends and will always turn to some of the company's senior leadership for life and career advice.

Though things settled down a bit post-IPO, I'd still say work/life balance is tough at Opower. People work hard because they love what they do, but they're still working really, really hard. Also, the transition from one primary product line to multiple product lines has been rocky, particularly as oil prices have been tanking and screwing with the entire industry. As the energy world settles out so too will Opower, as long as they solidify their newer products.
