Frontend Developer

Overview:

We are seeking a talented Frontend Developer to join our team working on a sophisticated data visualization and analysis platform built for semiconductor manufacturing. This role will involve developing complex, data-intensive user interfaces that enable engineers to analyze data, create custom visualizations, and derive actionable insights. You will be working on a modern React-based application that combines advanced charting capabilities, real-time notifications, and comprehensive data manipulation tools in an enterprise-grade environment. The ideal candidate will thrive in a fast-paced environment where performance, scalability, and user experience are critical. You'll collaborate with cross-functional teams including backend engineers, data scientists, and UX designers to build features that directly impact our customers' manufacturing processes. This is an opportunity to work on cutting-edge technology with complex state management, real-time data synchronization, and interactive data visualizations.

Responsibilities:

• Develop and maintain complex React components using TypeScript with strict type safety standards, ensuring robust and maintainable code across the application
• Implement advanced data visualizations using ECharts, , and custom charting libraries to display semiconductor wafer data, scatter plots, histograms, heatmaps, and statistical analyses
• Design and implement Redux-based state management solutions using Redux Toolkit and RTK Query for efficient API data fetching, caching, and real-time synchronization
• Build responsive, performant UI components with SCSS/Sass following BEM methodology and implementing dynamic theming (light/dark mode) across the application

• Integrate real-time features using SignalR/WebSockets for live notifications and data updates, ensuring seamless user experience during long-running operations

• Write comprehensive unit and integration tests using Vitest and React Testing Library

• Optimize application performance for large datasets (10K+ data points), implementing virtualization, memorization, and efficient rendering strategies
• Collaborate with backend teams to integrate RESTful APIs using Axios ensuring proper error handling and loading states
• Participate in code reviews, enforce ESLint/Prettier standards, and maintain high code quality through TypeScript best practices

Qualifications:

• 5+ years of professional experience with React (v18+) and TypeScript in production environments
• Strong expertise in Redux/Redux Toolkit including complex state management patterns, middleware implementation, and RTK Query for API integration
• Proficiency with modern build tools including Vite, npm/node ecosystem, and understanding of module bundling and optimization
• Advanced CSS/SCSS skills with experience in responsive design, CSS-in-JS patterns, theming systems, and preprocessor features
• Data visualization experience with libraries such as ECharts, , , or similar frameworks for creating interactive charts and graphs
• Solid understanding of TypeScript including advanced types, generics, utility types, and strict typing patterns for large-scale applications
• Testing expertise using modern testing frameworks (Vitest/Jest, React Testing Library) with proven track record of writing maintainable test suites
• Git proficiency with experience in collaborative workflows, branching strategies, code reviews, and CI/CD pipelines

Nice to Have

• Familiarity with Flexlayout-react or similar layout management libraries for complex, resizable panel interfaces
• Experience with real-time communication protocols (SignalR, WebSockets, Server-Sent Events)

• Background in data-intensive applications particularly in manufacturing, semiconductor, or scientific computing domains

• Understanding of design systems and component libraries

• Experience with Docker, Nginx and containerization for frontend deployment strategies
• Experience with Electron for building cross-platform desktop applications

Pay Range: CAD $80, CAD $110,000.00 /Yr.
