UX/UI Product Designer (Design Engineer)

About the Role

OOCA has been building digital mental health in Thailand since 2017: teletherapy, a clinic at Gaysorn, and mental health programs inside companies. We're hiring two designers who design and build. You'll do UX and UI across mobile and web, then ship the front end yourself. We prefer a software engineering background and will train you into an AI-augmented product designer who can build product independently.

Responsibilities

• Design UX and UI for mobile and web, end to end
• Build your designs in front-end code (React / TypeScript)
• Map end-to-end user journeys and detailed user flows, defining clear information architecture for booking, onboarding, and crisis moments
• Run user interviews: set the objective, recruit, moderate, synthesize
• Design AI-driven features: loading states, wrong answers, handoff to a human clinician
• Own our component library and design patterns in the repo
• Work directly with engineers, stakeholders, and the CEO
• Set the design standard for the team and teach what you learn

Qualifications

• Front-end code that ships. React and TypeScript preferred. Can clone a repo, run it, open a PR
• Daily use of AI coding tools (Claude Code, Cursor, or similar)
• Strong visual craft: type, spacing, hierarchy, restraint
• Responsive design experience, working alongside a dev team
• Advanced proficiency in Figma (mastering Auto Layout, components, variables, and interactive prototyping)for exploration and alignment, ensuring designs are structured logically for seamless translation into code
• Able to run a user interview that produces insight
• Clear communicator who manages their own deliverable priorities
• Fast learner, flexible, comfortable changing direction when evidence changes
• Working Thai and English

Preferred Qualifications

• Health, mental health, or another regulated industry
• Practical use of design thinking, Agile, or the hook model
• Accessibility and low-bandwidth mobile experience
