Job description

Are you a highly motivated and self-starting individual with a proven, project-oriented mindset? We're not offering a typical internship. This is an opportunity to join a small, elite team and build a tangible, high-impact product that will directly contribute to our next major product release. We are seeking a Full Stack Developer (MERN) Intern to help us build a new, AI-powered feature that will revolutionize how our users collaborate in real-time.

Your Mission:

The challenge is to seamlessly integrate a generative AI model into our existing platform. As the Full Stack Intern, your mission is to design, build, and deploy the new, standalone service that will power this capability. You will be responsible for the entire backend service, the API endpoints that interact with the AI model, and the real-time front‑end components that enable live updates for all users. This project is a core component of our upcoming product roadmap, and your contribution will be visible to thousands of our enterprise customers.

What You'll Work On (The Toolkit for Innovation):

This project requires a toolkit built for speed, performance, and modern development workflows. You will be working hands-on with the MERN stack ( MongoDB , Express.js , React.js , Node.js )

• Real-time Communication: Socket.IO for live messaging and collaboration [1, 1].
• API Management: Postman for testing and validating API endpoints.
• Version Control: Git and GitHub for collaborative development [1, 1].
• Cloud Deployment: Good to have deployment knowledge

What We Look For:

• The Builder Mindset: You are passionate about solving complex technical problems and thrive on independent work.
• A Demonstrable Portfolio: We require a demonstrable portfolio of personal projects, a public GitHub profile with active contributions, or a technical blog where you dissect new technologies.
• Foundational Knowledge: A strong understanding of data structures, algorithms, and software design patterns.
• Technical Skills: While a strong foundation in the MERN stack is preferred, candidates with demonstrable proficiency in other full-stack environments, such as Java/Spring Boot/React, who are eager to learn and adapt, are strongly encouraged to apply.

Required Skills

• Familiarity with at least one frontend framework (React, Nextjs, or Larvel).
• Knowledge of backend technologies (Node.js, Express, or PHP).
• Understanding of databases (SQL/NoSQL).
• Knowledge of Git/GitHub for version control.
• Strong problem-solving and analytical skills.
• Ability to work in a collaborative team environment.

Nice to Have (Optional)

• Understanding of RESTful APIs or GraphQL.
• Knowledge of deployment

What We Offer:

• Real Ownership: You will have complete ownership of a core product feature that will ship to production.
• Direct Mentorship: Work directly with senior engineers who will guide you but give you the autonomy to build.
• Meaningful Work: This is not a project that will be discarded. Your work will be a core part of our platform.
• Potential for Full-Time Conversion: Clear statement about conversion to a full-time role upon successful completion of the program.
