Backend Developer

Working Location: Empire Tower (100% onsite, accessible via BTS Chong Nonsi)

We are looking for a Backend Developer who wants to work on modern, high-volume, business-critical systems where backend engineering has real impact.

This is not a routine CRUD role. You will work on real transaction flows, complex business logic, system integration, performance, reliability, and production-grade platforms used in large-scale operations.

Our team keeps moving with modern technology. You will get exposure to modern .NET, cloud-native services, distributed systems, messaging, observability, automation, and AI-assisted development tools.

Why Join Us

• Work on real high-volume systems, not only internal admin tools
• Build backend services that directly support business-critical operations
• Learn complex transaction systems, integration patterns, reliability, and secure data handling
• Use modern engineering practices, cloud services, automation, and AI-assisted development
• Collaborate closely with product, business, QA, solution architects, DevOps, and external partners
• Grow toward senior developer, technical lead, solution design, or domain expert roles

What You Will Do

• Build and maintain backend services and REST APIs
• Implement complex business logic, validation, retry, routing, and status handling
• Integrate with internal platforms and external service providers
• Work with relational databases, query optimization, and data consistency
• Support asynchronous processing using queues, events, and background jobs
• Troubleshoot production issues using logs, metrics, dashboards, and monitoring tools
• Improve system performance, reliability, security, and observability
