Interaction Designer

You design the moment between the tap and the response — how a screen answers, how a gesture feels, how a flow carries someone from confused to done. Interaction design is the verb layer of UX: not what it looks like, not what it says, but how it behaves. Here's the honest picture, including why you see this title less often than you used to.

What the job actually is

Interaction designers define how a product behaves: the flows, states, transitions, feedback, and micro-moments that make software feel responsive instead of inert. Where a UI designer decides what the button looks like, you decide what happens when it's pressed — and half-pressed, and pressed twice, and pressed while offline. The day-to-day is flow mapping, state diagrams, high-fidelity prototypes (Figma, Principle, code-ish tools), motion specs, and long arguments about edge cases nobody else noticed. At many companies this work lives inside a 'product designer' title; at design-mature ones (and in automotive, gaming, hardware, and voice/AR) it's still its own discipline.

Is it actually you?

You'll probably love it if

You notice WHY an app feels good — the 200ms ease-out, the optimistic update — not just that it does
Prototyping is your native language; you'd rather show the behavior than describe it
Edge cases (empty, error, loading, offline) genuinely interest you
You think in systems and states, not screens
Motion, timing, and feedback feel like craft to you, not decoration

Maybe not, if

You want the visual-identity glory — that's the UI/brand side of the house
Documenting states and specs to the last pixel would bore you to death
You need your title to be widely understood — you'll explain 'IxD' forever
Ambiguity about where your role ends and UX/UI begins would grind you down
You're hoping to skip user research and just make things move nicely

The real day-to-day (no hype)

The title is consolidating into 'product designer.' Most companies now hire generalists and expect interaction design as one skill among several. Pure IxD roles cluster at design-mature tech companies, agencies, and non-screen domains — automotive, AR/VR, voice, hardware. Search for the skill, not just the title, or you'll think the market vanished.
Prototype fidelity is the whole interview. A portfolio of static flows won't cut it for a role about behavior. The candidates who win show working prototypes — and can narrate the decisions: why this transition, why this duration, what the failure state does. One deeply-explained interaction beats ten pretty screens.
AI raised the floor and the ceiling moved to you. Generating a decent-looking screen is cheap now. Knowing how the tenth state of a flow should behave when the network drops mid-payment — that's still human judgment, and it's exactly the layer interaction designers own. The skill got MORE valuable as the pixels got cheaper.
New surfaces keep re-creating the discipline. Every platform shift (touch, voice, AR, in-car, AI agents) starts with no interaction conventions at all — and someone has to invent them. If you time a platform early, 'interaction designer' stops being a legacy title and becomes the most important seat in the room.

How people break in — or switch in

The portfolio is everything and it must MOVE — 2–3 case studies with working prototypes, each narrating behavior decisions (states, transitions, feedback, edge cases). Coming from UI design: add flows, states, and motion specs to work you've already done. Coming from motion graphics or front-end: you're closer than you think — you already speak timing and states; wrap it in user-centered reasoning. Formal HCI degrees help at research-heavy companies but a great prototype outruns a diploma almost everywhere.

If you're a UI or motion designer, don't restart at junior — reframe. You've been doing interaction design every time you specced a hover state or an animation curve. Present it that way and interview at level.

Your application, already half-written

Here's a question every Interaction Designer application asks, answered the way pirch would — in a real voice, grounded in real experience:

“Walk us through an interaction you're proud of.”

My favorite is one most users never consciously saw. Our checkout had a 3-second payment call, and the spinner was killing conversion — people thought it froze and double-submitted. I redesigned the moment: button morphs to a progress state instantly (so the tap feels received), optimistic success animation starts at 90% confidence, and a designed failure state with a retry that preserves everything you typed. Double-submissions dropped 80% and support tickets about 'stuck payments' basically ended. I prototyped all four states in Figma with real timing before any code was written — the engineers built it from the prototype, not a spec doc. That's what interaction design is to me: the product's behavior under stress, designed on purpose.

pirch finds the interaction design roles that are actually you

Half these roles are titled 'product designer,' a quarter say 'UX,' and the good ones are buried in the noise. Tell pirch who you are and it hunts down real, still-open roles that match the work you actually want — with a tailored cover letter already written. No spray-and-pray. No dead links.

Common questions

What does an interaction designer actually do?

They design how a product behaves: flows, states, transitions, feedback, and micro-interactions. Where UI design decides how things look, interaction design decides what happens when you touch them — including the loading, error, and edge states most people never think about.

Interaction designer vs UX designer — what's the difference?

UX is the umbrella (research, architecture, flows, testing); interaction design is the specific discipline of behavior — how each moment responds. In practice many companies fold both into 'product designer.' Judge the role by the job description, not the title.

How much do interaction designers make?

Roughly $70k–$145k+ with a median around $100k, tracking closely with UX/product designer pay. Specialists in hot niches (in-car, AR/VR, AI-agent interfaces) at design-mature companies can go higher.

Do I need a degree to become an interaction designer?

No. A portfolio of working prototypes with clearly narrated behavior decisions is the actual credential. HCI degrees help at a handful of research-heavy employers, but shipped interactions beat coursework nearly everywhere.
