Senior UI Designer (contract position)

Описание

This position is only for a particular project, not a full time inhouse position.

As this is a contract-based cooperation, you will receive a salary based only on the number of worked hours. And a social package (sick leaves, days off, vacation, necessary equipment provision, etc) is not covered by Selecto.

Location: Preference for candidates working within or close to Madrid time zone (CET/CEST)

Industry: Sports / Major Live Events 

About the Role

We are looking for a Motion-Driven UI Designer to join our team and shape the visual and interactive experience of a large-scale design system used across web, mobile, and TV platforms for a high-profile international sports broadcasting project.

This role is ideal for designers who think beyond static screens - who design systems in motion, craft meaningful interactions, and bring digital products to life through animation, dynamics, and spatial thinking. Motion and interaction are not secondary - they are core to this role.

What You’ll Do

• Design UI components and scalable patterns for a cross-platform design system (web, mobile, TV).

• Define and implement motion and interaction principles as a foundational layer of the design system.

• Create dynamic behaviors: transitions, states, micro-interactions, focus logic, spatial movement, and responsive feedback.

• Develop interactive prototypes and motion explorations to communicate timing, rhythm, hierarchy, and emotional impact.

• Collaborate closely with developers to ensure high-quality motion implementation.

• Contribute to documentation that clearly articulates motion logic, interaction flows, and animation systems.

• Explore spatial and dimensional concepts (including 3D when relevant) to elevate broadcast and large-screen experiences.
  
  

What We’re Looking For

• Strong portfolio showcasing UI design with a clear emphasis on motion and interaction.

• Proven expertise in animation systems, micro-interactions, and interactive prototyping.

• Ability to design behaviors, not just interfaces - thinking in states, flows, and transitions.

• Experience working across multiple platforms (mobile, responsive web, TV/large screens preferred).

• Understanding of how motion enhances usability, storytelling, and brand expression.

• Experience contributing to or building design systems.

• Strong collaboration and communication skills.

• Comfortable working within Madrid time zone hours.
  
  

Nice to Have

• Experience with sports, live events, or broadcast interfaces.

• Proficiency in motion tools (After Effects, Principle, Figma Smart Animate, Lottie, etc.).

• Experience with 3D design or motion in 3D environments (Cinema 4D, Blender, or similar).

• Understanding of spatial UI, depth, lighting, and dimensional transitions.
