About the role

Sharaj Tech is a small, fast-moving technology company based in Noida that builds and ships web-based products end to end. As a MERN Full Stack Developer on our engineering team, you will own features across the entire stack — from pixel-accurate React interfaces to Express/Node APIs, MongoDB data models, and production deployment. This is a high-ownership, high-visibility role: with a tight-knit team of fewer than ten people, your work goes from idea to live product in weeks, not quarters, and you'll have a direct line of sight into how your code impacts real users and the business. We're looking for a developer who is equally comfortable debugging a tricky Mongoose aggregation as they are refining a component in Redux, and who genuinely enjoys collaborating with product and design to solve real problems. If you want to work with a modern JavaScript/TypeScript stack, keep learning new tools, and have real influence over architecture and engineering practices, this is the opportunity for you. About the Company: Sharaj Tech is a Noida-based technology company building and maintaining modern web applications for its clients and product users. Operating as an agile, small-team engineering organization, it values hands-on ownership, practical problem solving, and a modern JavaScript technology stack. As part of the team, you'll work closely with the whole engineering group and have a tangible impact on the products and the company's growth. Responsibilities: • Design, develop, and maintain full stack web applications using MongoDB, Express.js, React, and Node.js — owning features from concept through production. • Build responsive, accessible client-side interfaces in React/Redux, translating product and design requirements into clean, reusable components. • Develop and document RESTful APIs and server-side business logic in Node.js/Express, including authentication and authorization flows using JWT. • Design and optimize MongoDB schemas and queries with Mongoose, ensuring data integrity, sensible indexing, and performance at scale. • Write clean, well-tested, and maintainable code; participate in peer code reviews and contribute to shared engineering standards. • Integrate third-party services and APIs, and manage SQL data sources where relational storage is required. • Support build, release, and deployment workflows using Git, npm, Docker, and CI/CD pipelines, and troubleshoot production issues as they arise. • Collaborate closely with product, design, and fellow engineers in an Agile/Scrum cadence — estimating work, refining requirements, and continuously improving how we ship. Qualifications: • Proven experience building and shipping full stack web applications on the MERN stack (MongoDB, Express.js, React, Node.js) — professional or substantial project-based. • Strong JavaScript fundamentals, including ES6+ features, asynchronous programming, and modular code organization. • Solid hands-on experience with React (components, hooks, state management) and Redux or a comparable state management library. • Strong command of HTML5 and CSS3, including responsive layouts and cross-browser compatibility. • Experience designing and consuming REST APIs, with a clear grasp of HTTP, status codes, and JSON payload design. • Working knowledge of MongoDB and Mongoose — schema design, queries, aggregation, and indexing. • Familiarity with JWT-based authentication and secure handling of user sessions and credentials. • Proficiency with Git and GitHub/GitLab workflows — branching, pull requests, and code review. • Comfortable with npm-based tooling, package management, and modern build/bundling setups. • Debugging and problem-solving mindset, with the ability to diagnose issues across the client, server, and database layers. • Strong communication and team collaboration skills — able to explain technical trade-offs to non-technical stakeholders. • Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical experience. Benefits: • Direct ownership of features and real influence over architecture and engineering practices in a small, fast-growing team. • Exposure to the full product lifecycle — you'll see your code ship to real users quickly. • Mentorship and hands-on learning across a broad, modern JavaScript/TypeScript and cloud stack. • Flexible working hours and a hybrid-friendly schedule built around outcomes, not clock-watching. • Support for learning and professional development, including courses, certifications, and new tooling. • A collaborative, low-bureaucracy engineering culture where ideas are heard regardless of title. • Clear growth path toward senior/lead responsibilities as the team scales. • Paid time off and performance-based recognition for high-impact contributions.
