Sr. Java Developer

About Full Stack Developer:

We are looking for a Full Stack Developer with expertise in modern JavaScript frameworks — React.js, Next.js

on the frontend and Node.js, Nest.js on the backend — along with MongoDB for data management. You’ll be

working closely with cross-functional teams to build scalable, high-performance web applications and APIs that

power our digital cafeteria platform.

You’ll need to be comfortable shifting between frontend and backend tasks, contributing to architecture

decisions and working in a fast-paced environment.

Roles & Responsibilities:

• Develop and maintain scalable web applications using React.js and Next.js.

• Build robust RESTful APIs using Node.js and Nest.js.

• Collaborate with UI/UX designers to implement responsive and performant user interfaces.

• Integrate with databases (MongoDB) and third-party APIs.

• Write clean, maintainable and well-documented code.

• Optimize application performance and scalability.

• Participate in code reviews and contribute to best practices.

• Work closely with the QA team to debug and resolve issues.

• Assist in DevOps or production support tasks when required.

• Ensure the independent prioritization and delivery of high-quality features.

Prerequisites:

• Min. 2 years of professional experience as a Full Stack Developer.

• Strong proficiency in JavaScript, HTML, CSS.

• Hands-on experience with React.js and Next.js for web development.

• Solid understanding and experience with Node.js and Nest.js for server-side applications.

• Proficient in working with MongoDB or similar NoSQL databases.

• Familiarity with RESTful API design and integration.

• Experience using Git and modern development tools (e.g., VS Code, Postman).

• Ability to work in an agile, team-oriented environment.

• Strong problem-solving and communication skills.

Role Overview:

We're looking for a Senior Full-Stack Developer who doesn’t just write code—but builds systems, owns features end-to-end, and leverages AI tools to move fast and build smart. This isn’t a ticket-taking role. This is for builders who can architect, develop, and ship independently, with a bias toward action and clarity.

If you live inside your terminal, talk to Co-pilots like your pair programmer, and obsess over clean APIs and smooth user flows—let’s talk.

What you’ll do

• Take full ownership of features from problem → design → code → deploy → iterate
• Build modular, scalable APIs and frontend components using the MERN stack
• Use AI tools to write, debug, optimize code, and unblock yourself fast
• Integrate 3rd-party APIs, services, and AI capabilities where relevant
• Collaborate async with product, design, and other engineers
• Optimize performance, scalability, and dev workflows
• Own dev hygiene—documentation, tests, Git practices, CI/CD pipelines

Must-Haves:

• Bachelor’s degree in Computer Science, Engineering, or a related technical field
• 4–5 years of full-stack experience in production-grade MERN apps
• You’ve shipped products end-to-end, not just maintained features
• Strong in JavaScript/TypeScript, both on frontend and backend
• Solid foundation in system design, API design, and debugging
• Comfortable using AI-native tools to code faster and better
• GitHub is your second home. You write clean commits and structured PRs
• Cloud/infra experience (Vercel, AWS, Docker/Kubernetes)
