an open notebook on the discipline of UX engineering
We engineer the feel of software so it feels inevitable.
uxe.fyi is an open-source home for UX Engineering — the multidisciplinary craft that lives between engineering, design, and human behavior. A living handbook, a career bridge, a community of people who care how interfaces feel under the cursor.
01 — What is UX Engineering?
One role,
many shapes.
UX Engineering lives between engineering and design — but never in the same place twice. Hover any role to see how a UXE compares to the discipline next door.

02 — Career bridges
There is, finally,
a clear path in.
UX Engineering attracts people from very different starting points. Pick a path that already looks like you, and follow it without guessing.
03 — UXE Thinking
Less "how",
more "why does this feel right?"
The intellectual core of UX Engineering — short, opinionated essays on the ideas that shape how interfaces feel. Updated weekly.
01whyInvisible frictionThe cost of every extra click, every loading spinner, every form field that asks for something you already know.drafting02howCalm interfacesDesigning software that does not demand your attention — it earns it, briefly, and gives it back.drafting03whatEmotional latencyTime is not measured in milliseconds. It is measured in feelings — and feelings have their own physics.drafting04whyThe trust contractEvery interface makes promises. Every load, every error, every undo button is a promise being kept or broken.drafting05howOptimism as a featureShowing the result before the server confirms it. A small lie in service of a much bigger truth.drafting06whatAffordance is a verbA button is not affordance. Looking like something you can press at this moment — that is.drafting
04 — Interaction breakdowns
Look closer.
Touch them.
Real, working interactions — each isolated and annotated. Play with the controls. Read the why. Steal what you need for your own work.
05 — Built in public, day one
An open notebook
waiting for its people.
uxe.fyi is open-source and brand new. The structure is here — the handbook, the roadmaps, the breakdowns. Most of it is scaffolding, waiting for people who care about this stuff to fill it in.

The premise
Software is made of feelings. The people who care about that — who measure interfaces in milliseconds and millimeters and small acts of trust — deserve a name, a discipline, a community. This is for them.
