Roku

It had a lot of very senior engineers in the original group that started the company. Pay is good.

• Very few promotions within the company, even for people that deserve it.
• Middle management is technically weak and isn't able to recognize good technical decisions from bad choices.
• Weak managers can block the career path of good engineers.
• The company didn't survive growth pains and ended up with very weak middle management.

• Promote from within rather than hiring middle managers from outside the company.

• A very common pattern is a middle manager hired from outside the company will bring in friends from outside the company and then drive out long-term employees in the group.

• I've seen deserving senior engineers have to leave Roku in order to get a promotion they deserve and would have gotten at other companies.
