Frontend Engineer – React

About the role

We are looking for a Frontend Engineer specialized in React to help build and evolve our client‑facing ESG intelligence platform. You will own key parts of the application, collaborate on the data contract that powers the UI, and deliver interactive visualisations for non‑technical users.

Key responsibilities

• Design and implement screens and flows for the client portal using a modern React (v19) and strict TypeScript stack.
• Partner with platform engineers to define, version and maintain the API data contract that feeds the frontend.
• Create interactive dashboards and visualisations with Apache ECharts to present ESG and climate‑risk data.
• Implement authentication and multi‑tenant isolation to ensure each client only accesses their own data.
• Write typed, well‑tested code within a shared design system, adhering to high quality standards.
• Leverage AI coding tools such as Claude Code as part of the development workflow.
• Collaborate with product, data, and engineering teams to shape features and user experience.

Required profile

• 4+ years of professional experience building production‑grade React applications in TypeScript.
• Strong understanding of modern React patterns including routing, data fetching, caching, state management and form validation.
• Experience delivering data‑rich interfaces and turning complex data into clear visualisations.
• Commitment to security best practices, especially multi‑tenant isolation.

• React (v19)
• TypeScript (strict)
• Apache ECharts
• REST API integration and data contract design
• Authentication and multi‑tenant security
• Unit testing and end‑to‑end testing
• Single‑page application development
