Job Description

About you

You are a practiced designer/developer hybrid who has a mastery of skills and a passion for prototyping. You demonstrate thorough understanding of applied design skills, tools, processes, and development practices. You live happily in both engineering and design worlds (with a slight nudge to the latter) and actively seek to bridge them. While the focus of this role is prototyping you come with a hybrid design/developer skill set. Confident in both, you are ready to contribute as product designer and also develop, and maintain internal tools such as Figma plug-ins or the documentation platform for our design system. You are an enthusiastic team player who believes in the SoundCloud mission and is eager to help evolve our design language, practices, and team culture to their fullest potential.


The Role

You will build and maintain high fidelity prototypes that make our long term product vision tangible, and testable. Collaborating with cross functional teams you also create frameworks that enable product designers to create and iterate on medium fidelity prototypes that are linked to our API, and capable of audio playback. You will be responsible for ensuring that the design team at large is able to easily build and test experiences with these frameworks. 

As a UX Prototyper, you will collaborate with peers in Product Design, Research, Product Management and Engineering to build, test, and iterate on prototypes based on conversations, sketches, mock-ups, user journey maps and research findings. You should be comfortable iterating independently on prototypes, beyond specifications and assignments.

Fluent with APIs and a variety of tools and techniques (such as React Native, Framer, Principle, Swift, Origami …) you will use the most appropriate for the task at hand. Often, your code isn’t expected to be production-ready quality. In fact, you will often prioritize “getting things done” over quality of code.

In addition, you will support the evolution of our design language system, as well as internal tooling like building and maintaining custom plugins (e.g. for Figma) to support and streamline our Product Design workflow.



  • Create hi-fidelity interactive prototypes for storytelling as well as user testing and validation
  • Articulate UX implementations for core behaviours with prototypes and clear specifications
  • Identify areas for UX improvement, such as custom vs. native paradigms for navigation and transitions
  • Explore opportunities for creative animations, illustrations, haptic feedback, sound, etc.
  • Build tools that help operationalise and bring efficiencies to design and engineering activities.
  • Collaborate closely with Product designers on your prototypes to conceptualise ideas that push boundaries
  • Creatively think through user-needed edge cases to support product decisions and development clarity
  • Independently, you identify where additional elements/views are needed to supplement the specs you receive, and come up with proposals for these
  • Collaborate with UX research, product management, engineering, product marketing, and business teams to ensure a smooth product development process
  • Understand and determine the level of fidelity required for your contributions and ensure we’re prioritising our efforts effectively
  • Communicate and align expectations within your team and stakeholders.



  • Strong understanding of web protocols and front end technologies such as HTML, CSS, JavaScript, and React 
  • Use of advanced animations with CSS3, JavaScript, and/or prototyping software
  • Experience with industry design tools, including Sketch, Figma, Framer, Principle, Lottie, and Zeplin
  • Familiarity with APIs and Databases
  • Working knowledge of Git or another version control system
  • Prior experience with Design Systems and how they work
  • Experience building complex prototypes for mobile and web, preferably for a large-scale consumer platform
  • Ability to provide the rationale and trade-offs for your solution proposals 
  • Communication is a big part of your daily work. You’re not only interested in input from users, developers and everybody else, but you’re able to ask questions, give feedback and critique your peers’ design and tech solutions
