About the Role
Senior frontend engineer who will own core product surfaces of Jinba's workflow automation platform. You'll build the interfaces where enterprise users create, visualize, and manage complex automations through natural language. This role is for someone who thrives on hard UI problems: real-time collaboration, canvas-based editors, and making AI feel predictable and trustworthy.
Responsibilities
Build and own major product surfaces: workflow editor, execution monitoring, integration configuration
Architect frontend systems that scale with product complexity and team growth
Implement complex interactions: drag-and-drop, canvas manipulation, real-time updates
Collaborate with design to ship polished, production-ready interfaces
Improve developer experience: component patterns, testing strategies, build performance
Mentor engineers and establish frontend best practices as the team grows
Requirements
Technical Skills
5+ years of frontend engineering experience
Expert-level React and TypeScript
Deep understanding of state management patterns and when to apply them
Experience with complex UI: canvas editors, rich text, drag-and-drop, or similar
Strong CSS fundamentals; comfortable with Tailwind and modern styling approaches
Systems Thinking
Ability to architect frontend codebases that remain maintainable as they grow
Experience with performance optimization: bundle size, rendering, perceived latency
Understanding of accessibility standards and how to implement them practically
Familiarity with testing strategies for complex interactive UIs
Product Sense
Experience building developer tools, no-code platforms, or workflow products
Ability to make technical decisions that improve user experience, not just code quality
Comfort working directly with customers to understand pain points
Strong Signals
Frontend or full-stack roles at companies like Figma, Linear, Notion, Retool, Vercel, or similar
Experience building canvas-based or node-graph editors
Contributed to or maintained open-source component libraries
Background at early-stage startups where you owned entire product surfaces
Experience with real-time collaboration features (CRDTs, operational transforms, or WebSocket-heavy UIs)

Quality bar: you care about polish, edge cases, and the details users notice
Early-stage ready: comfortable with ambiguity and rapid iteration
