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
What We Are Looking For
* Strong experience in C# / .NET / ASP.NET Core Web API
* Good understanding of REST API design and backend development
* Experience with relational databases such as MySQL, Aurora MySQL, or SQL Server
* Strong debugging, troubleshooting, and root-cause analysis skills
* Understanding of Git and standard development workflow
* Ability to work with complex business logic and high-accuracy systems
* Good ownership mindset and willingness to understand business context
Nice to Have
* Experience with fintech, payment, banking, airline, e-commerce, or high-volume systems
* Experience with AWS, message queues, Redis, OpenSearch, MongoDB, or distributed logging
* Knowledge of authentication, authorization, secure data handling, and production support
* Experience with microservices, event-driven architecture, or third-party API integration
We offer an attractive remuneration package, a fast-paced and exciting working environment, and provide challenging opportunities for life-long learning and career development.
