We are looking for a Backend Engineer to join our banking platform team.
You will build production-grade backend services in C# / .NET, working on financial product flows where correctness, reliability, auditability, and maintainability matter.

- Design APIs, background workers, and message-driven workflows.
- Work with SQL databases, Entity Framework, and performance-sensitive data access.
- Apply clean architecture principles across use cases, domain logic, repositories, and infrastructure.
- Write meaningful unit and integration tests.
- Support production systems with good logging, monitoring, and failure handling.
- Collaborate with product, operations, QA, and other engineers to clarify requirements and deliver reliable solutions.

What we’re looking for
- Solid C# / .NET backend experience.
- Good understanding of REST APIs, SQL, and service-based architecture.
- Experience with testing, CI/CD, and code reviews.
- Awareness of messaging, retries, idempotency, concurrency, and transactional boundaries.
