More tickets is not the whole ladder
A senior engineer still writes code. But the visible difference is judgment: picking the right problem, reducing risk, raising the quality bar, and making other engineers faster.
The useful signal is usually already there.
Career systems are still systems. Pull out evidence and everything gets harder to debug.
Work at the constraint
Find the bottleneck the team keeps tripping over: unclear ownership, slow reviews, brittle deploys, missing docs, or risky architecture. Then make that thing better.
Scope is often measured by repeated problems removed.
Make impact legible
Track outcomes, not just effort. The work that multiplies others is easy to undercount unless you write down what changed.
Flip the switches and watch the story turn into a tiny operating model.
Senior is a trust shape
The career move is not to become important everywhere. It is to become reliable where the team most needs judgment.
