UI, UX: Who Does What? A Designer's Guide To The Tech Industry

Plus: How Apple, Facebook, Google, and more tech-world heavyweights describe their design jobs.

Design is a rather broad and vague term. When someone says "I'm a designer," it is not immediately clear what they actually do day to day. There are a number of different responsibilities encompassed by the umbrella term designer.

Design-related roles exist in a range of areas from industrial design (cars, furniture) to print (magazines, other publications) to tech (websites, mobile apps). With the relatively recent influx of tech companies focused on creating interfaces for screens, many new design roles have emerged. Job titles like UX or UI designer are confusing to the uninitiated and unfamiliar even to designers who come from other industries.

Let's attempt to distill what each of these titles really mean within the context of the tech industry.

UX Designer (User Experience Designer)

UX designers are primarily concerned with how the product feels. A given design problem has no single right answer. UX designers explore many different approaches to solving a specific user problem. The broad responsibility of a UX designer is to ensure that the product logically flows from one step to the next. One way that a UX designer might do this is by conducting in-person user tests to observe one's behavior. By identifying verbal and non-verbal stumbling blocks, they refine and iterate to create the "best" user experience. An example project is creating a delightful onboarding flow for a new user.

"Define interaction models, user task flows, and UI specifications. Communicate scenarios, end-to-end experiences, interaction models, and screen designs to stakeholders. Work with our creative director and visual designers to incorporate the visual identity of Twitter into features. Develop and maintain design wireframes, mockups, and specifications as needed."

Deliverables: Wireframes of screens, storyboards, sitemap

Tools of the trade: Photoshop, Sketch, Illustrator, Fireworks, InVision

UI Designer (User Interface Designer)

Unlike UX designers who are concerned with the overall feel of the product, user interface designers are particular about how the product is laid out. They are in charge of designing each screen or page with which a user interacts and ensuring that the UI visually communicates the path that a UX designer has laid out. For example, a UI designer creating an analytics dashboard might front load the most important content at the top, or decide whether a slider or a control knob makes the most intuitive sense to adjust a graph. UI designers are also typically responsible for creating a cohesive style guide and ensuring that a consistent design language is applied across the product. Maintaining consistency in visual elements and defining behavior such as how to display error or warning states fall under the purview of a UI designer.

"Concept and implement the visual language of Create and advance site-wide style guides."

You might hear them say this in the wild: "The login and sign up links should be moved to the top right corner."

Visual Designer (Graphic Designer)

A visual designer is the one who pushes pixels. If you ask a non-designer what a designer does, this is probably what comes to mind first. Visual designers are not concerned with how screens link to each other, nor how someone interacts with the product. Instead, their focus is on crafting beautiful icons, controls, and visual elements and making use of suitable typography. Visual designers sweat the small details that others overlook and frequently operate at the 4X to 8X zoom level in Photoshop.

"Produce high-quality visual designs—from concept to execution, including those for desktop, web, and mobile devices at a variety of resolutions (icons, graphics, and marketing materials). Create and iterate on assets that reflect a brand, enforce a language, and inject beauty and life into a product."

It is also fairly common for UI designers to pull double duty and create the final pixel perfect assets. Some companies choose not to have a separate visual designer role.

You might hear them say this in the wild: "The kerning is off and the button should be 1 pixel to the left!"

Interaction Designer (Motion Designer)

Remember the subtle bouncing animation when you pull to refresh in the Mail app on your iPhone? That's the work of a motion designer. Unlike visual designers who usually deal with static assets, motion designers create animation inside an app. They deal with what the interface does after a user touches it. For example, they decide how a menu should slide in, what transition effects to use, and how a button should fan out. When done well, motion becomes an integral part of the interface by providing visual clues as to how to use the product.

"Proficiency in graphic design, motion graphics, digital art, a sensitivity to typography and color, a general awareness of materials/textures, and a practical grasp of animation. Knowledge of iOS, OS X, Photoshop and Illustrator as well as familiarity with Director (or equivalent), Quartz Composer (or equivalent), 3D computer modeling, motion graphics are required."

You might hear them say this in the wild:"The menu should ease-in from the left in 800ms."

UX Researcher (User Researcher)

A UX researcher is the champion of a user's needs. The goal of a researcher is to answer the twin questions of "Who are our users?" and "What do our users want?" Typically, this role entails interviewing users, researching market data, and gathering findings. Design is a process of constant iteration. Researchers may assist with this process by conducting A/B tests to tease out which design option best satisfies user needs. UX researchers are typically mainstays at large companies, where the access to a plethora of data gives them ample opportunity to draw statistically significant conclusions.

"Work closely with product teams to identify research topics. Design studies that address both user behavior and attitudes. Conduct research using a wide variety of qualitative methods and a subset of quantitative methods, such as surveys."

UX designers also occasionally carry out the role of UX researchers.

Deliverables: User personas, A/B test results, Investigative user studies & interviews

Tools of the trade: Mic, Paper, Docs

You might hear them say this in the wild: "From our research, a typical user..."

Front-End Developer (UI Developer)

Front-end developers are responsible for creating a functional implementation of a product's interface. Usually, a UI designer hands off a static mockup to the front-end developer who then translates it into a working, interactive experience. Front-end developers are also responsible for coding the visual interactions that the motion designer comes up with.

Tools of the trade: CSS, HTML, JavaScript

You might hear them say this in the wild: "I'm using a 960px 12-column grid system."

Product Designer

Product designer is a catch-all term used to describe a designer who is generally involved in the creation of the look and feel of a product.

The role of a product designer isn't well-defined and differs from one company to the next. A product designer may do minimal front-end coding, conduct user research, design interfaces, or create visual assets. From start to finish, a product designer helps identify the initial problem, sets benchmarks to address it, and then designs, tests, and iterates on different solutions. Some companies that want more fluid collaboration within the various design roles opt to have this title to encourage the whole design team to collectively own the user experience, user research, and visual design elements.

Some companies use "UX designer" or simply "designer" as a catch-all term. Reading the job description is the best way to figure out how the company's design team divides the responsibilities.

"Own all facets of design: interaction, visual, product, prototyping. Create pixel-perfect mocks and code for new features across web and mobile."

"I am looking for a designer"

This is the single most common phase I hear from new startups. What they are usually looking for is someone who can do everything described above. They want someone who can make pretty icons, create A/B tested landing sites, logically arrange UI elements on screen, and maybe even do some front-end development. Due to the broad sweeping scope of this role, we usually hear smaller companies asking to hire a "designer" rather than being specific in their needs.

The boundaries between each of these various design roles are very fluid. Some UX designers are also expected to do interaction design, and often UI designers are expected to push pixels as well. The best way to look for the right person is to describe what you expect the designer to do within your company's process, and choose a title that best represents the primary task of that person.

    "The broad responsibility of a UX designer is to ensure that the product logically flows from one step to the next". According to my opinion this is very limited to what the Interaction designer has as resonsability, something about the bigger picture taken in consideration is missing in this definition if we want to apply it to the UX designer. The UX designer in this case has been the one who actually found out that we needed the product in the first place. Do you agree?

  • Lele7design

    "...ensure that the product logically flows from one step to the next." This sounds to me more like what the Interaction designer does, very limited definition if used for UX design.

  • Thameem

    Greta articles, Thank you for sharing. Could you please tell me what are the factors and elments a better ui design.

  • I've spent the last 3ish years working in and around the UK government as a content designer. We're at the heart of the design team, focusing on long-form copy as well as microcopy in interactive flows, help text, labelling, figuring out how to lay out a page, what questions to ask, how to phrase them...

    My job title doesn't really exist out of government, but I'm hoping it's just a matter of time.

  • Raowa

    The subtleties between all the 'Designer' profession's is still very vague. The job descriptions are quite similar but the technical skills however do differ. Anyways, interesting article!

  • Zeeshan

    This is an excellent and high quality article. Thank you for writing it. You put some good work into putting it all together in one place and remove many confusions.

  • Stacey Northup

    Great article! It all comes down to the fact that UX and UI are equally important, but they don't equal each other. Here's a SlideShare we put together explaining the differences between UX and UI >>

  • Aakash Joshi

    How does all the mentioned roles fall for the same aesthetic sense? Who takes those decisions?

    "Visual designers are not concerned with how screens link to each other, nor how someone interacts with the product. " - Really? How the screens link and how someone interacts, is build upon the experience path created for the product and it is very necessary for all the roles to have a good understanding of How Why Whose and What.

    But, still curious about the collaboration of all the roles for one product. Does all rely on faith on each others talents and visualisation? And confused about the comparison of a creative job with that of a doctors' or surgeons'.

    Still I found it a really good read. Thanks for sharing your views.

    While many legacy internet companies from the Web 2.0 days still have it as a job title (here's looking at you Yahoo!), the "Visual Designer" who "pushes pixels" isn't a thing anymore. It comes from the days of skeuomorphism when every button had to have shadows and interfaces had to look 3d.

    Nowadays, design on the web has progressed to the sophistication of the print world, where nuanced taste and style in typeface choice, layout, and photographic art direction are more important than 3d painting on elements. These are all relevant in the context of the user experience and the usability of the user interface. Because of this, the "product designer" job title is becoming more dominant. It better encompasses the disparate blend of functions that go into designing the front-end of a web product in 2015.

  • mcruzg5708

    Glad to have bumped into this article. Exactly spoke my mind on how I personally describe each element of design within the design industry. As a lot of companies nowadays are very unclear and/or trying to basically hire a person who does all the work (UX,UI, VISUAL DESIGN) for cost consolidation purpose??

    It's like metaphorically saying for instance, A hospital or a clinic is needing a Doctor who does brain surgery, dental practice, and eye surgery all at once.

  • pamo

    More like needing a painter who can purchase material, prepare the surface, paint and finish. Not a lot to ask really, you can slice any profession into smaller areas of responsibility, there's too much fluff around setting boundaries for design work these days.
