Ask HN: Is long-term employee commitment to the same company still appreciated?

I often times see a Linkedin/resume of a senior engineer where they have jumped ship every couple of months, staying max <=2 years in every company they have worked at. Imho, I always thought this was a red flag during the hiring process at a new company, as it doesn't show any long term commitment. I can understand junior/graduate employees jumping ship often in the beginning, but for +10 YOE software engineers, I find it odd.

In contrast, staying too long at a single place could make it seem like a developer doesn't want any changes.

What is your opinion on this?
