Job Description

As a Lead User Experience (UX) Designer, you help determine the experience architecture of our clients’ digital products. Combining stellar UX and analytical skills, you take ideas from conception to execution—collaborating with your team, navigating ambiguity, and balancing priorities as you push toward the goal and deliver on time. 

Focusing on one client helps you deliver quality work, but you could be working across multiple accounts, too. You’ve got the grit to lead the execution of UX deliverables—wireframes, interactive prototypes, user flows, site maps, and usability test plans. Owning multiple, small-to-medium features or one major feature from design through completion can be challenging, but your skills, know-how, and attention to detail are equal to the task.  

You Will:  

  • Design holistic systems, flows, and interfaces that are simple, elegant, and beautiful through detailed wireframes, visual compositions, and prototypes that communicate design intent, and client and user feedback. 
  • Provide guidance, leadership, and support to other UX designers and the project team.  
  • Lead discussions with stakeholders regarding feature design, using an organized and methodical approach. 
  • Balance creative requirements with client business requirements. 
  • Manage time effectively and execute according to commitments. 
  • Apply a critical lens to your work and the work of others in service of the solution. 
  • Demonstrate team orientation and build rapport with creative teammates, strategists, content strategists, marketing science, and producers. 
  • Clearly articulate complex ideas to both the internal team and client. 
  • Anticipate upcoming client and team needs, identify risks, and mitigate appropriately.
