A UI designer owns the visual layer of your product: screens, components, states and the design system engineers build from. Polished Dribbble shots are common, so we screen for shipped product work, components other designers reused, and how they handle the empty, error and loading states nobody puts in a portfolio.

What a good UI designer has done by day 90

A UI hire shows its value when engineers stop making visual decisions by default. Each stage below has a signal that predicts it, and we test for that signal before you meet anyone.

Milestone 1 of 5: Audits the product's interface

Weeks 1 and 2

Every screen type, the component library if there is one, and the places where the product looks or behaves inconsistently. Pairs with engineers to learn how the front end is built.

On track looks like an inventory of components and inconsistencies, ranked by how often users meet them.

How we test for it before you meet them

A short exercise in our screen: one of your product screens, with its empty, error and loading states. We score the states, not just the happy path.

Milestone 2 of 5: First screens shipped

Weeks 3 to 6

A feature or flow designed with the product manager and built with engineering, including every state, responsive behavior and interaction detail engineers need.

On track looks like shipped screens that match the design file, with no visual decisions left to engineering.

How we test for it before you meet them

We ask for a shipped feature with the design file beside the live product. The gap tells us how they hand over and follow through.

Milestone 3 of 5: Components in the system

Weeks 7 to 10

The components that appear across the product, buttons, inputs, tables, modals, designed once with variants and states, documented and matched in code.

On track looks like a component set in the design library that engineers build from directly.

How we test for it before you meet them

We look for component or design system work and ask which of their components other designers and engineers used after they left.

Milestone 4 of 5: Consistency across the product

Weeks 11 to 13

Older screens brought into line with the system, with accessibility checked: contrast, focus states, touch targets and type scale.

On track looks like fewer one-off styles in the product and accessibility issues fixed on key screens.

How we test for it before you meet them

A reference call with an engineer or product manager about how this designer worked day to day and what shipped because of them.

Milestone 5 of 5: Raising the visual standard

After day 90

Strong UI designers start shaping the design system's direction, mentoring others and working with marketing so the product and the website feel like one brand.

On track looks like the head of design trusting them with the design system's roadmap.

How we test for it before you meet them

We ask what they would change first in your product's interface and why. A specific answer grounded in users beats a list of visual trends.

What the seat owns

Five responsibilities. If the seat is mainly research and flows, it is a UX designer; if it is mainly the marketing site, it is a web designer.

  1. Screens and flows, visually

    The visual design of product screens and flows, from the main path to every edge case.

  2. Components and states

    Reusable components with their variants and states: empty, loading, error, disabled and hover.

  3. The design system

    Type, color, spacing, icons and components documented so others design and build consistently.

  4. Handover engineers can build

    Specs, responsive behavior and interaction details clear enough that the build matches the file.

  5. Accessibility in the interface

    Contrast, focus states, touch targets and readable type across the product.

What it is not

Three neighboring seats absorb work people assume belongs here. Drawing the line wrong is how a UI hire ends up running research or designing ads.

  • UX Designer

    That seat ownsHow people get things done: research, flows, wireframes and usability testing.

    Hire it instead whenthe product looks fine but people struggle to complete tasks in it.

  • Web Designer

    That seat ownsPage designs for the marketing site and landing pages.

    Hire it instead whenmost of the work is your marketing site rather than your product.

  • Visual Designer

    That seat ownsThe look of the brand across digital touchpoints: layout, type, color and imagery.

    Hire it instead whenthe need is brand expression across channels, not the product interface.

Three versions of the seat

The title stays the same; the product does not. Pick the one that matches yours.

Portfolios of concepts with no shipped product
Works well with
A product manager and engineers who review designs early

Builds and maintains the component library and documentation the whole product team uses.

What they optimize
Consistency and speed for everyone who designs and builds

Six interview questions that separate UI designers

The questions we ask in our own screen. Use them in yours; the warning signs are as useful as the answers.

The scorecard every UI designer is scored against

Every candidate we put forward is scored on these five, and the scores travel with the shortlist, gaps included. Four out of five with a named weakness beats a clean sweep you cannot verify.

What we scoreWeak evidenceStrong evidence
Shipped product workConcepts and redesigns that never shipped.Live features with the design file beside the product.
States and edge casesHappy paths only.Empty, error, loading and permission states designed with a purpose.
Components and systemsEvery screen designed from scratch.Components others reused, confirmed by a designer or engineer.
Working with engineeringStatic handovers and no follow-through.Specs, reviews during the build and solutions within technical limits.
AccessibilityLeaves accessibility to engineering.Checks contrast, focus, targets and labels as a routine part of design.

What a UI designer is paid in the US

Public US benchmarks, read October 2026. Salary.com and Built In agree closely on this seat, with Built In’s self-reported average total of $93,039 just above Salary.com’s band. Seniority is the big step, and the BLS band is wide because one occupation covers web, UI and UX designers.

Employer questions about hiring a UI designer

A UI designer owns the visual layer of a software product: how screens look, the components they are built from and every state those components can be in, from empty and loading to error and disabled. They maintain the design system, hand over designs engineers can build exactly, and check accessibility, so the product looks and behaves consistently as more people work on it.

Salary.com puts a UI designer at $77,020 to $92,508 base, with a median of $85,450 (October 2026). Built In’s self-reported figures agree closely: an $83,000 median base and $93,039 average total pay, rising to a $101,000 median base for a senior UI designer. The BLS band for web and digital interface designers runs from $73,290 to $158,820 across all industries.

A UX designer works out how people get things done: research, flows, wireframes and usability testing. A UI designer decides how it looks and behaves on screen: visual design, components, states and the design system. Many product designers do both, but strong teams often split them as they grow. If users struggle to complete tasks, hire UX first; if the product looks inconsistent, hire UI.

Shipped product work, not just concept shots. Look for the design file beside the live product, components or a design system others reused, and the states most portfolios skip: empty, error, loading and permissions. Ask them to design those states for one of your screens. It takes less than an hour and shows more than any polished case study.

Not to ship production code, but they need to understand how interfaces are built: how components map to code, what is expensive to build, how layouts respond to screen sizes and how accessibility works in practice. Designers who understand the build hand over designs that ship close to the file and work well with front-end engineers.

Often that is the reason to hire one. A UI designer can audit the product, find the components that repeat and build the first version of a design system while shipping features, which is easier than retrofitting consistency later. Look for someone who has built a system from an existing product, not only someone who has worked inside a mature one.

Ten working days from a signed brief to a shortlist of three to five calibrated designers, each with a portfolio review and our states exercise scored. Interview speed decides the rest: good UI designers rarely run one process at a time, so a decision within a week of the first interview keeps them. Most can start two to four weeks after accepting.
