Target

Good work/life balance.

Teammates and coworkers are typically positive and good to work with.

Decent PTO after a year or two.

Upward mobility and opportunity for career growth are very limited. The top levels (i.e., directors, senior managers, VPs, etc.) all play things very politically, and it's a constant rotation amongst themselves. Once you're hired in, they will do whatever they can to keep you around that salary, even if you're promoted.

I speak from experience and a decent tenure with the company. When I've pressed upper management about it, I was told, "Your best bet would be to leave and come back."

Actually allow your engineers to utilize their "50 days of learning" for career growth. Encourage and provide the resources for their internal growth. Lastly, encourage the upper tiers to free up money and pay your engineers in line with the actual market, not what was in place 10 years prior.
