Design Engineer
Directly mentions vibe coding and AI-assisted workflows; role helps designers become effective vibe coders and builds prototype-to-production systems.
About the Role
Design Engineer responsible for bridging design and frontend engineering to shape and ship polished UI experiences end-to-end. Own the craft layer—animations, micro-interactions, loading and error states—and build tooling and workflows so designer prototypes flow into production.
Job Description
Role
Comfy is hiring a Design Engineer who sits at the intersection of design and frontend engineering. You’ll take rough ideas, iterate in Figma or code, and ship polished UI experiences end-to-end. The role focuses on the craft layer of the product—transitions, micro-interactions, typography, loading and error states—and on improving workflows between design and engineering so prototypes can be production-ready.
Key Responsibilities
- Own the quality bar for UI: identify rough edges, propose fixes, and ship improvements, often autonomously.
- Sweat the details: transitions, easing curves, skeleton/empty/error states, responsive behavior, and accessibility.
- Collaborate with designers from concept to production, iterating together in Figma and code.
- Design and build greenfield surfaces end-to-end (pages, tools, experiences) that integrate with the product.
- Implement small QoL improvements from idea to production with minimal design input.
- Act as a designer when needed and comfortably wear both design and engineering hats.
- Help designers become effective vibe coders by building workflows so designer-made prototypes are usable by engineers or AI agents.
- Create systems for prototype-to-production handoff and keep Figma design system and the component library in sync.
- Contribute to and evolve the design system: tokens, components, patterns, and documentation.
Requirements
- Fluency across design and frontend engineering (either a frontend engineer with a designer’s eye or a designer who writes production-quality code).
- Strong expertise with modern frontend tooling; TypeScript experience is explicitly mentioned.
- Proficiency in Figma and fundamentals of product design: layout, typography, color, spacing.
- Strong visual taste and attention to detail.
- Self-directed and able to ship improvements without waiting for tickets.
- Familiarity or experimentation with AI-assisted workflows, such as agents or LLMs, and vibe coding.
- Awareness of accessibility best practices and responsive behavior.
Nice to Have
- Experience building or contributing to a design system at scale.
- Background in motion design or creative coding (Canvas, WebGL, shaders).
- Portfolio, blog, or open-source work demonstrating craft.
