Full Stack Developer Internship

About Us

Sahii.in is a fast-growing Indian e-commerce platform supplying mobile spare parts at wholesale pricing to repair technicians across India. We're solving real problems around trust, pricing transparency, and accessibility in the mobile repair ecosystem — and we're building fast.

Our stack runs on Node.js, Express, MongoDB, Redis, and EJS. We're a small team where your work ships to real users quickly.

Role Overview

We're looking for a Full Stack Developer Intern who is equally comfortable on the frontend and backend — someone who can pick up an existing codebase, understand it, and make meaningful improvements across performance, features, and reliability. You'll work directly on our core product alongside the founding team.

What You'll Be Doing

• Building and improving features across the full stack — from UI components to backend APIs
• Identifying and fixing bugs that affect real users and revenue
• Improving site performance, page load times, and mobile experience
• Integrating third-party services (payments, analytics, marketing tools)
• Contributing to SEO improvements — both technical and on-page
• Writing clean, maintainable code in an existing production codebase

What We're Looking For

Must Have

• Solid understanding of JavaScript — both frontend and Node.js backend
• Experience working with databases (MongoDB or similar)
• Ability to read, understand, and extend existing codebases confidently
• Good grasp of responsive UI and CSS
• Familiarity with REST APIs and third-party integrations
• Git proficiency in a team environment

Good to Have

• Prior internship or freelance experience, especially in e-commerce
• Exposure to performance optimization or SEO best practices
• Experience with Redis, Razorpay, or similar tools
• Familiarity with React or Next.js

Who Will Thrive Here

• You've built something real and shipped it — not just followed along a tutorial
• You can work independently, manage your time, and flag blockers early
• You take ownership of your work and care about the end user's experience
• You're comfortable with ambiguity and fast-moving priorities
