Founding Product Designer

About the role

Sekai is building the TikTok for mini apps — an AI-driven consumer platform where people create, remix, share, and play interactive content instantly.

We are a Series A company backed by Khosla, a16z, Mayfield, and A*, with $30M raised to date. We are remote-first across all positions and are looking for ambitious, AI-native builders who want to help shape the next generation of consumer social products.

ABOUT THE ROLE

We are looking for our first design hire: a Founding Product Designer who can own the user experience end-to-end and raise the quality bar of the product.

This is not a supporting design role. We want someone who can act as a true UX owner — someone who can identify what feels broken or confusing, define better product experiences from first principles, and help shape the product DNA, visual language, and design system of the company.

The right person has strong product taste, excellent UX judgment, solid visual craft, and is highly AI-native. Mandarin Chinese is required for this role.

RESPONSIBILITIES

• Own end-to-end design across key product surfaces on mobile and web

• Drive UX for major product flows and make clear product experience decisions

• Improve the overall quality, clarity, and polish of the product

• Define and evolve product DNA, visual language, interaction patterns, and design systems

• Work closely with founders, product, and engineering to shape and ship new experiences

• Use modern AI and design tools to explore, prototype, and iterate quickly

REQUIREMENTS

• 2+ years of product design experience, ideally in consumer or mobile-first products

• Strong UX judgment and product sense

• Strong visual design skills and high taste level

• Ability to design from scratch and bring structure to ambiguous problems

• Strong systems thinking and experience building reusable patterns or design systems

• High ownership and comfort working in a fast-moving startup

• Comfortable working closely with engineers

• Highly AI-native and comfortable using modern tools in daily workflow

NICE TO HAVE

• Experience with consumer social, creator, gaming, or AI products

• Frontend or engineering background

• Ability to prototype in code or implement light frontend work

• Experience as an early or founding designer at a startup

BENEFITS

• Competitive base salary + meaningful equity

• Full health insurance

If you are excited about building at the frontier of AI, consumer social, and interactive entertainment, we would love to hear from you.

At Sekai, you will work with an AI-native team, move fast, own meaningful problems, and have the flexibility to explore new ideas from an early stage.
