How do you tell junior, mid, and senior designers apart?

Junior does what they are told. Mid starts asking what should be done. Senior stops to clarify which problem is being solved and why it has business value. Years help, but environment and challenge quality matter as much.

How does a junior grow to senior when junior roles are scarce?

Seniors must build structure: scope, process, room to act independently, and weekly sparring. “Senior plans, junior draws” fails because juniors only learn Figma mechanics. Real growth needs ownership inside guardrails.

How does a consultant bill client time honestly?

Tuomas’s rule: log an hour only if you can justify it when asked. Learning a new method on the client’s dime is not billable unless agreed upfront. The metric is value to the client, not time for its own sake.

Summary

Tuomas and Mikki on junior, mid, and senior UX: how growth really works, honest billing, and the questions that unlock better design.

About The Good Side in this episode

Tuomas Kaartoluoma on growing juniors: seniors need to provide structure, scope, and weekly sparring. He got his own project and a weekly mentor as an intern, not just waiting for direction. At The Good Side, juniors get autonomy in proportion, not only pixel work under a senior.

Key discussion points

Junior draws what is asked, mid asks what to draw, senior asks which problem this solves
Years alone do not level you up; environment and challenge quality matter more than title seniority
The senior’s job is to define process, scope, and checkpoints; the junior operates inside that independently
Seniors do not know all answers; they tolerate ambiguity better and have processes to work through it
“Dumb” basic questions in a new industry get the whole team thinking from first principles
Fastest growth route: new industries, varied projects, and actively seeking discomfort
Consultant billing test: “if asked about this, can I justify it?” If not, do not bill the hour
