Job description

Full Stack Engineering Intern (FastAPI + Next.js)

Freshers

Remote/Hybrid

Posted on 21 September 2026

Objective

Build and ship the products that power our business. You own backend services end to end, wire up AI/LLM features that actually solve user problems, and connect it all to a clean Next.js/React frontend. You will start as an intern and, if you deliver, convert to a full-time engineer.

Role and responsibilities

• API Development: Design, build, and maintain backend services and REST APIs using FastAPI, with clean schemas, validation, and sensible error handling.
• Data Layer: Model and query relational data (PostgreSQL), write efficient queries, manage migrations, and keep the database healthy as the product grows.
• AI/LLM Integration: Build features on top of LLM APIs (prompting, retrieval, function calling, basic agent workflows) and turn rough ideas into working, testable endpoints.
• Frontend Delivery: Implement and connect UI in React/Next.js, consuming your own APIs so features work end to end rather than in isolation.
• Shipping and Quality: Write tests, handle auth and basic security, debug production issues, and ship in small, reviewable increments.

Requirements

• Pursuing (4th Year) or recently completed (2025/26 Batch) a degree in Computer Science, Engineering, or a related field, with real projects to show.
• Solid Python fundamentals and hands-on experience (coursework, side projects, or prior internship) with FastAPI or a similar framework (Flask, Django).
• Working knowledge of React and Next.js, and comfort building a feature across both frontend and backend.
• Understanding of databases and SQL, plus version control with Git.
• Familiarity with LLM APIs (OpenAI, Anthropic, or similar) and a genuine interest in building AI-powered features. Prior experience is a strong plus.
• A self-starter who can take an ambiguous problem, ask the right questions, and ship something useful.
• Competitive stipend, with a pre-placement offer on successful completion.
• Direct ownership of features that ship to real users.
• Mentorship and fast feedback from senior engineers.
• Flexible work environment with remote and hybrid options.
