• You value clean, testable, and maintainable code and believe good architecture makes teams faster and more effective.

What You'll Do

Design, build, and deploy backend systems using modern software architecture practices and code that can be easily maintained and extended.

Collaborate with experts to define our domain model and ensure clear separation of concerns through principles inspired by Domain-Driven Design and Onion Architecture.
