The role

As a Senior Backend Developer in our Reservations Squad, you will take ownership of the financially critical heart of Lodgify's platform-the booking lifecycle, financial calculations, and real-time availability calendar. You will tackle technical challenges head-on by advancing our event-driven architecture and completing critical database migrations while playing a key role in raising the bar for engineering reliability and team mentorship.

What you'll do

  • 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.
