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)

Ownership-oriented: you want to own outcomes, not just ship tickets

Quality bar: you care about polish, edge cases, and the details users notice

Early-stage ready: comfortable with ambiguity and rapid iteration
