Translate data-heavy systems and workflows into experiences that feel light, structured, and focused - helping expert users prioritize, act confidently, and stay in flow. Apply a strong product sense and understanding of business levers to ensure design decisions are not only user-centered but strategically aligned. Drive quality and consistency across key product areas, while also owning and executing design strategy for critical pillars of the Kokai platform. Partner closely with Product and Engineering to shape roadmaps, define requirements, and advocate for user-centered, insight-driven decision-making. Coach and influence other designers through critiques, systems thinking, and storytelling - modeling best-in-class design practices and raising the bar across the team. Contribute to Harbor, our unified design system, to push quality and consistency across all surfaces and components. Lead by example through design critiques, mentorship, and collaboration-helping foster a culture of continuous improvement, excellence, and shared ownership of quality. Qualifications
Bachelor's degree in Design, HCI, Computer Science, or a related field - or equivalent practical experience (Master's degree preferred). 10+ years of experience in product design or UX, including work on enterprise-grade or data-rich applications. 4+ years of experience leading high-impact design initiatives or strategic projects across teams or product areas. Proven experience working in cross-functional teams, influencing outcomes through collaboration, systems thinking, and storytelling. Strong visual and interaction design skills, with a portfolio that demonstrates high standards of craft, clarity, and user-centered problem solving. Proficiency in Figma and the ability to prototype at multiple levels of fidelity to communicate and validate ideas effectively. Experience partnering with executive stakeholders and contributing to product vision and roadmap through design leadership. A track record of translating complex user needs and business goals into scalable, elegant solutions. Familiarity with advertising technology, programmatic platforms, and campaign optimization tools is a strong plus. The Trade Desk is an equal opportunity employer.
