MERN Stack Developer

About the Role

We’re looking for a Full Stack Developer who deeply cares about how things look, feel, and flow. Someone who writes elegant code and designs beautiful, functional experiences that users love.

You’ll work at the intersection of design and engineering, turning ideas and prototypes into smooth, high-performing applications built on React and Node.js. This role suits developers who think in pixels, obsess over transitions, and genuinely want every click and animation to feel just right.

Responsibilities

• Develop modern, responsive interfaces using React.js, TypeScript, and UI frameworks (Tailwind, Material, or similar).
• Transform design mockups and Figma prototypes into production-quality web experiences.
• Build scalable APIs and backend systems using Node.js, Express.js, and REST/GraphQL.
• Design and manage databases (MySQL, MongoDB) with efficient and clean data flow.
• Optimize for speed, accessibility, and smooth user interactions across devices.
• Collaborate with designers and product teams to refine visual and interaction details.
• Deploy, monitor, and scale applications on AWS (EC2, S3, CloudFront, Lambda, RDS).
• Maintain high code quality through clean architecture, testing, and peer reviews.

You’ll Fit Right In If You

• Love crafting beautiful, consistent, and intuitive interfaces.
• Notice when a button is off by a few pixels and care enough to fix it.
• Balance creativity with engineering discipline.
• Enjoy solving real user problems with thoughtful design and seamless performance.
• Have opinions about UX — and back them with reasoning, not ego.

Tech Stack

• Frontend: React.js, TypeScript, Redux / Zustand, Tailwind CSS, Styled Components
• Backend: Node.js, Express.js / NestJS, RESTful APIs, GraphQL
• Databases: MySQL, MongoDB, PostgreSQL (optional), Redis (caching)
• Cloud & Tools: AWS (EC2, S3, CloudFront, RDS, Lambda), Docker, CI/CD, GitHub Actions
• Bonus: Next.js, Figma-to-code workflows, WebSockets, Serverless functions

Qualifications

• 3–7 years of full-stack experience with a strong frontend/UI focus.
• Proven experience creating visually stunning and user-centered web apps.
• Deep understanding of frontend architecture, design systems, and responsive layouts.
• Solid knowledge of databases, API design, and deployment best practices.
• Bachelor’s degree in Computer Science or equivalent practical experience.

Why Join Us

• Build products that users actually love to use.
• Collaborate with a design-first, detail-oriented team.
• Work with modern tech and creative freedom.
• Shape the product’s visual identity and user experience end-to-end.
