About Zymix

Zymix is building an AI-powered social platform centered around local communities, real-world events, and intelligent experiences. We're creating the next generation of social products where AI is deeply integrated into how people discover, connect, and interact.

As an early-stage startup, you'll have the opportunity to work on real products that ship to users, collaborate closely with experienced product and engineering teams, and make a meaningful impact from day one.

What You'll Do

• Design intuitive and engaging mobile app experiences for iOS and Android.
• Create user flows, wireframes, high-fidelity UI, and interactive prototypes in Figma.
• Collaborate closely with Product, Engineering, and AI teams to bring ideas from concept to production.
• Contribute to and help evolve our design system.
• Rapidly iterate based on user feedback, product metrics, and business goals.
• Use modern AI tools to prototype, validate, and refine product ideas.
• Participate in product discussions and contribute to UX decisions.

What We're Looking For

Required

• Recently graduated in Product Design, UX/UI Design, Interaction Design, HCI, or a related field.
• Experience designing mobile apps (iOS and/or Android).
• Experience working on products that have been implemented or shipped—not just concept designs.
• Strong portfolio demonstrating end-to-end product thinking and execution.
• Proficiency in Figma (Auto Layout, Components, Variables, Prototyping).
• Strong understanding of mobile UX and interaction design principles.
• Experience collaborating closely with engineers throughout implementation.
• Hands-on experience with AI-assisted development ("vibe coding") is required. You should be comfortable using AI tools such as Cursor, Claude Code, Lovable, Bolt, v0, or similar to rapidly prototype and iterate on ideas.
• Ability to thrive in a fast-paced startup environment.
• Fluent in both English and Mandarin Chinese (spoken and written). Excellent English communication skills are essential.
• Must be based in London and available to work with the team in person on a regular basis.

Nice to Have

• Experience designing consumer or social products.
• Experience with AI products or conversational interfaces.
• Experience building or maintaining design systems.
• Motion design or illustration skills.

What You'll Get

• Work on products used by real users.
• Collaborate directly with Product, Design, Engineering, and AI teams.
• Own meaningful product features from concept to launch.
• Gain hands-on experience building AI-native consumer products.
• Flexible working environment.
• Outstanding interns will be considered for a full-time Product Designer position
