Apply to Critical MassWe are looking to add Freelance Lead User Experience Designers to our Talent Roster for quick turnaround, shorter-term project engagements!
As Lead User Experience Designer, you're the rare leader who thinks like both a strategist and an artist. You speak fluent UX—information architecture, research, usability—but you also speak design—visual systems, motion, art direction. And increasingly, you speak AI: architecting conversational interfaces, exploring vibe-coded experiences, leveraging machine learning to create next-gen user experiences. You understand that great design extends beyond owned platforms—into the interfaces you design within third-party and media channels where you partner to maximize user engagement. You're looking to build and lead a team of UX and Product Designers who are equally fired up about creating experiences that are strategically sound, visually stunning, and genuinely innovative.
You juggle multiple complex projects without breaking a sweat, pivoting between high-level strategy sessions and detailed design feedback. You're the collaborator who bridges disciplines—connecting research to design, design to development, and all of it to business outcomes. You thrive in fast-paced environments, champion the user's voice against competing agendas, and mentor your team with the same rigor you apply to your own work. This role demands someone energized by the full spectrum of design—from wireframe to final pixel.
