Critical Mass are looking for a Lead UX Designer to come and join the London team!

• 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.

You Have: 

• 3-5 years of related industry experience in UX
• 2-4 years of experience in the role of senior UX designer or equivalent role.
• Effective communication skills, both orally and in a variety of written and diagrammatic forms.
• Proven interpersonal skills, client relation skills, and ability to work in a team environment.
• Experienced, innovative and forward-thinking mindset with demonstrated leadership of projects from concept to completion. 
• Thorough, detail-oriented, and highly organized working style with the ability to multi-task and meet tight deadlines.
• Flexibility and adaptability to fast-paced and changing environments.
• A deep appreciation and understanding of user experience including research, information architecture, usability testing, and applying it to create compelling digital experiences.
• Portfolio of work demonstrating creative thinking, problem solving, process, and quality spanning various digital platforms.
