Senior Frontend Engineer

The role

You will own core product surfaces of Jinba's workflow automation platform. You will build interfaces where enterprise users create, visualize, and manage complex automations through natural language.

What you will do

• 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

Required qualifications

• 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
• 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
• 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

Nice to have

• 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)
