Your Challenge

The Frontend Engineer is to build and improve web applications used by the Forecasting and Replenishment (FNR) team. This role focuses on creating reliable, fast, and easy-to-use interfaces for business users managing replenishment parameters, reviewing order proposals, monitoring exceptions, and taking action. You will work closely with Backend Engineers, Product, and business stakeholders to deliver production-grade features that have real operational impact.

• Build and maintain React applications using TypeScript with strong attention to usability, performance, and maintainability.
• Implement end-to-end user workflows for FNR systems (for example parameter setup, proposal review and approvals, dashboards, and exception handling).
• Collaborate with Backend Engineers to design and consume APIs effectively, including pagination, filtering, search, and error handling.
• Translate requirements into clean UI architecture: reusable components, predictable state management, and consistent UX patterns.
• Build data-heavy screens including tables, filters, forms, charts, and drill-down views with a strong focus on clarity and speed.
• Implement role-based access and authentication flows as required by internal systems.
• Ensure high quality through testing, code reviews, and disciplined release practices.
• Improve frontend developer experience: component standards, documentation, performance budgets, and reducing UI regressions.
• Work with stakeholders to iterate quickly through demos and feedback loops, while keeping the UI stable and consistent.

Requirements:
• Strong experience with TypeScript and React in production environments.
• Solid understanding of HTML, CSS, responsive layout, and modern browser behavior.
• Experience building complex, data-driven interfaces (tables, forms, filters, CRUD flows, dashboards).
• Experience integrating with REST APIs and handling client-side concerns such as loading states, caching, retries, and error messaging.
• Good understanding of frontend architecture concepts such as component design, state management patterns, and code organization.
• Familiarity with frontend testing practices (unit tests and integration tests) and ability to write maintainable tests.
• Strong debugging skills and ability to diagnose issues across UI, network, and API layers.
• Clear communication and collaboration skills, able to work with engineers and non-technical stakeholders.
• Experience with common React ecosystem tools such as React Query, Redux Toolkit, Zustand, or similar state/data management libraries.
• Experience with UI component libraries (Material UI, Ant Design, Chakra UI, or similar) and designing reusable component systems.
• Experience building charts and analytics views (for example Recharts, Chart.js, ECharts, or similar) with correct data representation.
• Experience with performance optimization: bundle size reduction, memoization strategies, virtualized lists, and rendering profiling.
• Experience with accessibility best practices and UI quality standards.
• Familiarity with CI/CD pipelines for frontend projects and release automation.
• Experience working in supply chain, retail, or operations-heavy domains.
