Design System Design Intern (Monetization Ads) - 2027 Summer

As the window of TikTok’s business services, our TikTok UED Monetization team aims to enable clients to effortlessly connect with audiences and maximize brand potential. We want to ease and inspire clients to achieve their goals, explore more possibilities, and create value with TikTok.

About the role

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.

Internships at TikTok aim to provide students with hands-on experience in developing fundamental skills and exploring potential career paths. A vibrant blend of social events and enriching development workshops will be available for you to explore. Here, you will utilize your knowledge in real-world scenarios while laying a strong foundation for personal and professional growth.

Responsibilities

• 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.

Requirements

• 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.

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.

Pay

The hourly rate range for this position in the selected city is $30–$50.

Benefits

• Day one access to health insurance, life insurance, and wellbeing benefits.
• 10 paid holidays per year and paid sick time (56 hours if hired in first half of year, 40 if hired in second half of year).
• Interns who are not working 100% remote may also be eligible for housing allowance.
