Junior Software Engineer

Aro is a Sri Lanka–focused technology platform built to simplify how fitness studios run their businesses and how customers engage with them.

Today, many studios still rely on WhatsApp, spreadsheets, manual payments, and fragmented tools to manage classes, schedules, payments, and clients. Aro exists to fix that by providing a clean, modern system that helps studios operate professionally while making life easier for customers.

We already have a working MVP in production. This role focuses on strengthening what exists, improving reliability, and helping shape the next phase of the product as we scale.

We are a small, focused team, and you’ll work closely with the founder and experienced developers, gaining real-world exposure to how startup products are built, maintained, and evolved.

Role Overview

This is an entry-level engineering role designed for someone early in their career who wants hands-on experience working on a live production system.

The core focus is maintaining and improving an existing codebase—fixing bugs, implementing small but meaningful feature enhancements, and gradually improving code quality across backend and frontend systems.

You won’t be thrown in alone. You’ll receive guidance, code reviews, and architectural support from senior developers while still owning day-to-day development tasks and learning how real products are maintained over time.

You will be working on software used by real studios and customers.
