Pros

Great colleagues and friendly environment, really good work life balance. Very smart people and learning a lot

Cons

Pay is just so so much lower than other quantum companies. Leadership and HR know this but don't have plans to change anything. I think they still view things from the Honeywell perspective of a giant old company.

Pros

There are some decent work/life balance flexibility. Life is great if you're a physicist. Lots of opportunity there.

Cons

Outside of the physicists, and their management structure, the rest of the place is kind of a nightmare. IT isn't even worth applying to. And if you're an engineer or tech, you get treated as a second class citizen. Management tends to have zero accountability and pass everything downhill, and even if you have a crazy list of accomplishments, you'll never get recognized for it. They're SUPER shady about how they terminate people, and word is HR management is starting to try and rein in flexible work arrangements.
