Design Engineer (Product Design & Flutter)

atFastwork Technology Co., Ltd.

Design Engineer (Product Design & Flutter)

Bangkok, Thailand (Full-time)


Role Summary
We’re hiring a Design Engineer—a rare hybrid who sits at the intersection of Product Design and Mobile Engineering. You will own the experience end-to-end, from concepting UX in Figma to shipping production-ready Flutter UI that feels “alive,” with pixel-perfect craftsmanship and high-quality micro-interactions.
You reduce handoff friction by being both the “translator” and the "builder"—ensuring the original product idea isn’t diluted during implementation, while setting a high bar for how Fastwork feels to users.
Responsibilities
End-to-end ownership: Lead features from vague concepts high-fidelity designs
  • production-ready Flutter implementation.
  • Craft & micro-interactions: Design and implement animations and transitions where motion is part of the UX (not just decoration).
  • Flutter development: Build high-performance UIs, including proper state management and a fluid experience across devices.
  • Visual communication: Apply the “Don’t Make Me Think” principle—use visual cues and intuitive interactions to reduce cognitive load.
  • Design system architecture: Maintain and evolve the design system; ensure Figma components map 1:1 to the Flutter widget library to increase velocity across the organization.
  • Backend integration: Connect the UI to backend services; understand API integration and basic backend logic to work independently, end-to-end.
Qualifications
  • Proven hybrid experience in UI/UX design and mobile development.
  • Strong in the core stack: Figma (Auto Layout, components, prototyping), Flutter/Dart (widget trees, custom painters, animation controllers), Basic backend/API understanding (RESTful services; Firebase, Go, or Node.js are examples)
  • “Craft” mindset: You notice 1px inconsistencies, contrast issues, and unnatural curves.
  • High agency: Proactive, comfortable with ambiguity, and not waiting for perfect specs.

Bonus Points
  • Experience with Rive, Lottie, or other advanced animation tools.
  • Experience building and maintaining scalable design systems.
  • A portfolio that showcases live apps or code—not just static images.
