About the Role: 

• We are seeking a skilled and forward-thinking Backend Engineer to join our growing team in the EdTech industry. This is an opportunity for a technically strong and curious professional who is passionate about building scalable digital systems that power meaningful learning experiences. 
• In this role, you will develop and maintain backend services using Ruby on Rails, design and optimise APIs, and ensure our platform is in keeping with new technology development, including managing effort to port the platform away from Ruby to more modern backend technologies, such as Nodes or Rust. 
• Beyond backend development, this position offers the opportunity to grow into infrastructure and DevOps responsibilities, helping shape the foundation of our next-generation learning ecosystem. 

Key Responsibilities 

• Design, build, and maintain efficient, reusable, and reliable Ruby on Rails code. 
• Develop and optimise APIs and ensure smooth data interchange across systems. 
• Integrate front-end elements with server-side logic for a seamless user experience. 
• Troubleshoot and resolve performance bottlenecks, bugs, and scalability challenges. 
• Ensure high performance, code quality, and clean architectural design.
• Contribute proactive technical suggestions — improving systems and workflows, not just following directions. 
• Collaborate closely with designers, front-end developers, and educational content teams. 
• Learn and gradually take ownership of infrastructure, deployment, and automation tasks. 
• Build and implementation of proprietary ML/AI learning and coaching metrics.
• Leverage AI-driven tools and workflows to enhance productivity and code reliability. 

Skills and Experience 

• Degree in Computer Science, Software Engineering, or a related field (or equivalent experience). 
• 3+ years’ experience in backend development with Ruby on Rails. 
• Solid understanding of databases (PostgreSQL, MySQL), RESTful APIs, and code versioning tools (Git). 
• Familiarity with front-end technologies (JavaScript, HTML5, CSS3) and MVC architecture. 
• Understanding of cloud infrastructure (AWS, GCP) or a strong willingness to learn DevOps practices. 
• Proven ability to write clean, maintainable, and testable code. 

You Are 

• Analytical and detail-oriented with strong problem-solving skills.
• Proactive and independent — able to anticipate needs and suggest improvements.
• Collaborative, communicative, and comfortable working across disciplines.
• Curious and eager to learn new technologies, especially in infrastructure and automation. 

• Join a truly international team where collaboration spans multiple countries, requiring strong English communication skills for effective teamwork. 
• Enjoy a hybrid working model with the flexibility to work from home while spending most of your time in our modern co-working space in Saigon. 
• Be part of a fast-growing, purpose-driven company at the intersection of technology, education, and innovation.
