We are seeking a hands-on Senior Software Engineer II React / Next.js to build and scale production-grade web applications.

This role is ideal for engineers with strong fundamentals in JavaScript, TypeScript, and modern web architecture, who can work across the stack using Next.js (App Router, RSC, API Routes) on the frontend and Node.js/Express on the backend.

You will focus on performance, reliability, and clean code design while collaborating with cross-functional teams to deliver high-quality features.

Key Responsibilities :

- Design, develop, and maintain front-end and back-end modules using Next.js, Node.js, and Express.

- Implement SSR, SSG, ISR, and edge deployments (Vercel / Cloudflare) for performant, resilient applications.

- Build and integrate REST and GraphQL APIs, ensuring efficient communication between client and server.

- Optimize web performance, including Core Web Vitals, Lighthouse scores, bundle size, and runtime efficiency.

- Leverage CDNs, caching layers (Redis, Cloudflare), and best practices in client-server architecture.

- Ensure code quality through unit and integration tests using tools such as Jest and Playwright.

- Collaborate closely with design, backend, and DevOps teams to deliver secure, scalable features.

- Participate in code reviews, uphold engineering best practices, and improve overall code quality.

- Mentor junior developers, provide technical guidance, and help drive architectural decisions.

- Contribute to system design discussions with a focus on scalability, fault tolerance, and maintainability.

Skills & Qualifications :

- Experience: 4+ years of experience in full-stack web development.

- Languages & Fundamentals: Strong foundation in JavaScript, TypeScript, ES6+, and browser internals.

- Frontend: Expertise in React 18+ and Next.js 13+ (App Router, Server Components, Server Actions, API Routes).

- Backend: Good knowledge of Node.js, Express.js, and RESTful API design principles.

- Databases: Experience with PostgreSQL/MySQL and ORMs such as Prisma or Sequelize; exposure to Redis is a plus.

- Styling & UI: Familiarity with Tailwind CSS, Shadcn UI, or Styled Components for building modern interfaces.

- Architecture & Scaling: Understanding of client-server architecture, CDN usage, caching strategies, load balancing, and basic fault tolerance.

- Performance & Optimization: Hands-on experience with performance tuning, Core Web Vitals, and bundle optimization.

- Testing & Quality: Experience with unit and integration testing (Jest, Playwright or similar frameworks).

- DevOps & Tooling: Familiarity with Git, CI/CD pipelines, and deployments on platforms like Vercel, AWS, or Dockerized environments.

- Problem-Solving: Strong debugging skills, analytical thinking, and a system-design mindset.

- Collaboration: Ability to work effectively in cross-functional teams and communicate technical concepts clearly.

Good To Have :

- Exposure to GraphQL, WebSockets, or Server-Sent Events (SSE) for real-time features.

- Experience with serverless deployments (Vercel functions, AWS Lambda, Cloudflare Workers).

- Understanding of authentication and authorization flows (JWT, OAuth).

- Additional experience with testing tools such as Vitest or Cypress.

Youll Thrive In This Role If You :

- Have a strong end-to-end understanding of how web applications work (DNS, CDN, HTTP, rendering).

- Think in terms of architecture and trade-offs, not just implementation details.

- Enjoy building clean, performant, and maintainable applications from the ground up.
