Description

We are looking for a Remote Full-Stack Software Engineer specializing in Ruby on Rails to design, scale, and maintain our core e-commerce applications, marketplace integrations, and retail tools.

Because this is a remote role, we value engineers who possess clear written communication, high self-motivation, and the ability to drive features from database schema design to frontend deployment independently.

Key Responsibilities

• Core Web Platform: Design, build, and maintain scalable web applications and APIs using Ruby on Rails.
• E-Commerce & Marketplace Integrations: Build and maintain integrations connecting our core systems to regional marketplaces and retail APIs.
• Frontend Engineering: Develop responsive, clean UI components using React.js and modern JavaScript/CSS.
• System Reliability & Infrastructure: Monitor, optimize, and maintain application performance across our cloud hosting platforms (AWS / DigitalOcean).
• Documentation & Clean Code: Write clean, maintainable, and well-tested code accompanied by clear documentation for workflows and API endpoints.

Requirements

• Core Technical Stack: Strong hands-on production experience with Ruby on Rails and SQL databases (PostgreSQL or MySQL).
• Frontend Proficiency: Solid experience with React.js, modern JavaScript, HTML5, and CSS3.
• Cloud & DevOps Basics: Familiarity with deploying and managing Rails applications on cloud environments (AWS, DigitalOcean, Heroku, or similar).
• Remote Competency: Resourceful, disciplined, and comfortable working asynchronously with high autonomy.
• Communication: Excellent written English skills for code documentation, issue tracking, and team collaboration.

Nice to Have

• Hands-on experience with e-commerce frameworks or engines (e.g., Spree, Solidus, Shopify API).
• Experience with mobile web or cross-platform frameworks (React Native).

Work Details

• Work Arrangement: 100% Remote
• Working Hours: Monday to Friday, 9:00 AM – 6:00 PM (Singapore Time, GMT+8) or local equivalent within ±1–2 hours.
• On-Call Availability: Occasional standby support outside core hours for critical bug fixes, server outages, or urgent production issues.
• Team Structure: Flat hierarchy, direct access to technical leads, zero corporate red tape, and direct ownership of production features.
