How will you make an impact?

Architect and evolve the booking core, managing the end-to-end lifecycle, quotes, taxes, fees, and financial ledger logic.

Drive event-driven messaging using RabbitMQ outbox/inbox patterns and Kafka (Avro) to guarantee reliable data fan-out across payments, messaging, and channel managers.

Lead the architectural transition from EF6/SQL Server to EF Core 8/PostgreSQL, executing zero-downtime schema updates that pave the way for continuous delivery.

Decouple high-churn aggregates by strengthening anti-corruption boundaries and isolating cross-domain communication.

Optimize our calendar backend-for-frontend service to deliver real-time availability and overbooking protection under strict latency requirements.

Elevate system reliability by defining SLOs, implementing robust idempotency patterns, and refining observability in Datadog.

Empower and mentor fellow engineers through constructive peer reviews, architectural documentation, and shared ownership of critical systems.

What makes you a great fit?

7+ years of professional experience building scalable backend services in C# and .NET Core / .NET 8.

3+ years of proven hands-on experience designing and operating distributed, event-driven architectures with RabbitMQ or Kafka.

Deep practical knowledge of database internals, Entity Framework / EF Core, and executing zero-downtime schema migrations on PostgreSQL or SQL Server.

Experience applying Domain-Driven Design (DDD), CQRS, onion/layered architecture, and Anti-Corruption Layer (ACL) patterns.

Strong focus on operational excellence, testing, logging/APM instrumentation (Datadog), and idempotency design.

A collaborative mindset focused on mentoring teammates, writing clear documentation, and solving complex problems pragmatically.

How can you earn extra bonus points?

Experience working in a microservices architecture.

Knowledge use of DevOps tech. (K8s, Docker, Helm, GCP, ...).
