Product Designer (Design Engineer) / UX-UI Developer
Salary: ฿55,000 – ฿80,000 per month
About us
Sunday Cloud is a fast-growing technology company with a startup culture, flexible working hours, and work-from-home flexibility. We are not just users of AI. We are AI builders and initiators, creating new platforms and technology with the ambition to help reshape Thailand's tech landscape. We give our people real ownership, decision-making authority, and direct access to decision-makers, with less hierarchy and more freedom to build, experiment, and make things happen.
About the role
We run multiple products at once, including B2B commerce, a community platform, and an AI assistant. We're looking for a Product Designer who can design with depth and ship their own frontend to production. We want a designer who codes, not a developer who can lay out a page. In this role, your work doesn't end at the Figma file.
