Principal UX Designer

CreativeX is transforming how brands and creators bring their ideas to life through Creative Studio, our state of the art suite of AI-powered creative tools. Our vision for the Creative Studio to empower people to achieve more faster, with tools that feel as intuitive and inspiring as working with a creative partner. We are seeking a Principal UX Designer who thrives on building delightful experiences designed for a diverse set of creatives. You will lead by doing — rolling up your sleeves to design, prototype, and deliver user experiences that transform advertising. In this role, you will move fluidly from high-level strategy to pixel-level execution, getting your work into customers' hands quickly and learning from their feedback. You will thrive in a start-up-like environment, unblocking yourself, navigating ambiguity, and maintaining a relentless focus on delivering high-quality, real-world experiences. Your deep knowledge of generative AI will help shape how we build the next wave of agentic, creative-focused solutions. This role is based in New York, NY or Seattle, WA.

Key Job Responsibilities:

• Define and own the design vision and strategy for the Creative Studio, empowering customers with generative AI and agents
• Lead hands-on design execution — from wireframes to polished prototypes to production-ready assets
• Rapidly explore, build, and validate ideas to uncover the best interaction models for AI-driven creativity
• Design elegant, intuitive, and trustworthy user experiences that seamlessly fit into creative and advertising workflows
• Collaborate deeply with engineering, applied science, research, and product teams to align on goals and drive execution
• Operate independently, proactively unblocking yourself and delivering high-quality solutions
• Champion inclusive, responsible, and scalable AI-driven design practices
• Mentor other designers while modeling a builder mindset: speed, creativity, and a bias for action
• Advocate for the unique needs of advertising asset creators and creative professionals
