We want to ease and inspire clients to achieve their goals, explore more possibilities, and create value with TikTok. We're hiring a Design System Design Intern to help evolve Keystone, the design system powering TikTok's Monetization products (ads and business-facing experiences). Keystone enables product teams to build consistent, high-quality UI through reusable components, patterns, and guidance-improving both user experience and product development efficiency. As an intern, you'll contribute directly to Keystone's core libraries and documentation, partnering with design system designers and cross-functional teams (product design, engineering, content design) to ship scalable system improvements that land in real product surfaces. In this role, you will: - Design or extend components, variants, and patterns (e.g., forms, navigation, tables, empty/error states), and create scalable specs (states, interactions, responsive behavior, accessibility). - Improve usage guidance, do/don't examples, and rationale to reduce ambiguity for product teams. Help maintain libraries and documentation across Figma + Keystone website. - Assist with UI audits for consistency and system alignment. Support adoption and migration by mapping legacy patterns to Keystone equivalents and clarifying best-practice usage. - Partner with engineers to ensure feasibility and crisp handoff. Participate in critiques and design reviews; incorporate feedback quickly and communicate tradeoffs clearly. Qualifications Minimum Qualifications: - Currently pursuing a Bachelor's Degree in Product Design / Interaction Design / HCI / Visual Communication (or equivalent experience). - Strong fundamentals in UI craft and interaction thinking (states, flows, usability). - Comfort working in Figma (components, variants, auto layout, styles/tokens preferred). - Must be able to commit to a 12-week full-time work period during Summer 2027. Preferred Qualifications - Basic understanding of design systems concepts: tokens, component design, governance, accessibility. - Experience collaborating with engineers (class projects or hackathons count). - Familiarity with accessibility basics (WCAG concepts, keyboard navigation, contrast). - Experience applying AI tools in design workflows (e.g., drafting guidance, synthesizing feedback, generating UI variations), with thoughtful judgment on quality, bias, and privacy.
