Software Engineering Intern (Ruby on Rails | React)

Location: India

Department: General

About the team

What you'll work on

• Building an internal tool screen end to end — a Rails controller and service on the backend, a React page on the front end
• Adding a filter, report, or workflow to the tools our operations and service teams use every day
• Writing model and controller tests, and component tests for the UI you build
• Investigating a production data question and turning the answer into a fix
• Cleaning up something slow, confusing, or duplicated — with the freedom to propose how

Our stack

• Backend: Ruby 3.4, Rails 8, PostgreSQL, Redis, Solid Queue for background jobs
• Frontend: React with TypeScript, Inertia.js, Tailwind CSS, Vite; Hotwire (Turbo + Stimulus) in older parts of the app
• Testing: Minitest on the backend, Jest on the front end
• Everything else: Git, GitHub, CI on every pull request

What we're looking for

• Graduating batch of 2024 or later, with a degree in Computer Science, Engineering, or equivalent practical experience
• Solid programming fundamentals — data structures, how a web request actually works, how to model data in a relational database
• Comfortable writing SQL and reasoning about a schema
• Able to read code you didn't write and figure out what it does
• Clear written communication — most of our collaboration is asynchronous across time zones
• Willing to ask questions early rather than stay stuck

• Hands-on experience with Ruby on Rails — a personal project, a college project, an earlier internship, open source, anything you can walk us through
• Hands-on experience with React; TypeScript is a bonus, not a requirement
• Familiarity with Git workflows: branches, pull requests, resolving a conflict without panic
• Any experience writing automated tests

• Exposure to Tailwind, Inertia, or server rendered React
• Background jobs, caching, or anything you've had to make faster
• A public GitHub profile, a blog, or something you've built and can talk about honestly
