Senior work is decisions not hours

Right now at a senior engineer level, your job already changed. You stop getting paid mainly for your own hours of work. You get paid for the decisions you make and the systems you set up that keep working even after you close your laptop.

An opinion you share in a meeting fades in a week. A reminder you send fades in a day. But a decision written down, and a system that enforces it without your help, keeps working long after everyone forgot you said anything.

But if you set up routines, sanity checks, architecture decisions, automatic rules, agents etc, that is what sticks around and continuous to deliver value.
