HubSpot

HubSpot really puts a lot of effort into having a positive, healthy environment for engineers to work, without going too far over the top.

The technology that I get to work with is really modern and innovative.

Honestly, most importantly I would say is the intrinsic value given to getting things done right. That's not to say that things aren't done hacky and fast to just make them work, but it's acknowledged that this is taking on technical debt that will need to be paid off later.

Thought is given to good API design, and there's a goddamn amazing design/UX team.

Oh, and the UI library itself is top-notch. It makes tasks that used to take weeks or days take hours or minutes.

All of the backend stuff is written in Java. So if you like Java...

It is a decently sized company, however well they do of hiding it. There are managers, and managers' managers, and managers' managers' managers... but at least they're all super smart and competent.

Keep on keepin' on.
