Position Overview

We are seeking a highly skilled Senior Full Stack React Developer to join our engineering team and contribute to the design, development, and delivery of modern web applications. This role requires ownership of end-to-end feature development across both frontend and backend systems, including React, TypeScript, Node.js, Express, API integrations, and testing.

The ideal candidate is a senior individual contributor who can independently drive technical decisions, design reusable application patterns, contribute to architecture discussions, and deliver high-quality, scalable solutions in an Agile environment.

Key Responsibilities

Full-Stack Feature Ownership

• Build and own complete vertical slices of functionality across frontend and backend layers.
• Develop React components, TypeScript interfaces, RTK Query endpoints, Node.js services, and Express APIs.
• Design scalable and reusable application patterns that support future feature development.
• Ensure consistency across application architecture and implementation.

Frontend Development

• Develop modern React applications using React 18 best practices.
• Implement functional components, custom hooks, Suspense, lazy loading, and performance optimizations.
• Create reusable and maintainable UI components using design system libraries.
• Build dynamic forms using React Hook Form with Yup or Zod validation.

• Utilize Redis caching strategies to improve performance while managing cache consistency.

Architecture & Design

• Participate in technical design discussions and architectural decision-making.
• Design reusable component APIs and backend service patterns.
• Define endpoint structures, caching approaches, and permission models.
• Identify opportunities for code reuse and standardization across the application.
• Evaluate technical risks and propose scalable solutions.

Testing & Quality Engineering

• Develop tests alongside implementation rather than after development.
• Write behavioral tests using Vitest and React Testing Library.
• Create unit, integration, and asynchronous workflow tests.
• Validate loading states, error handling, and API interaction behavior.
• Ensure high code quality through automated testing and peer reviews.

Agile Collaboration

• Participate in sprint planning, backlog grooming, and estimation sessions.
• Collaborate closely with product managers, designers, architects, and engineering teams.
• Review user stories and proactively identify missing requirements or design gaps.
• Document technical decisions, assumptions, and implementation approaches.
• Participate in code reviews and knowledge-sharing activities.
