- 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, ...).
