Job Description

We are looking for an experienced Senior Lead React Developer with expertise in React, TypeScript, and test automation to lead our frontend development efforts. This role involves designing, implementing, and maintaining a scalable, high-performance frontend architecture while ensuring robust automated testing frameworks. You will work closely with cross-functional teams to deliver a stable, maintainable, and user-friendly application.

Our stack includes React with TypeScript on the frontend, Python for the API layer, and Playwright/Cypress for test automation. The ideal candidate is a frontend expert who understands modern state management, component-driven architecture, and best practices for performance optimization.

Responsibilities

1. Frontend Architecture & Development

Design and develop scalable, maintainable, and reusable React components.

Implement TypeScript best practices for strongly typed applications.

Architect efficient and optimized state management using Redux, Zustand, or Context API.

Improve application performance with techniques such as code splitting, lazy loading, memorization, and virtualized lists.

Ensure responsive and accessible UI using modern CSS methodologies (CSS-in-JS, Tailwind, Styled Components).

2. Test Automation & Quality Assurance

Develop and maintain automated testing frameworks using Playwright and Cypress.

Ensure comprehensive unit, integration, and end-to-end testing coverage.

Build test strategies for cross-browser and cross-device compatibility.

Implement strategies to reduce flakiness in test automation and maintain stability over time.

Work closely with backend and DevOps teams to integrate tests into CI/CD pipelines.
