 Who we are
 
Lodgify is a fast-growing scale-up company leading the vacation rental industry. Backed by $30M in funding, our platform empowers property owners and managers worldwide to efficiently manage and grow their business through technology.
 
Headquartered in sunny Barcelona, we're now a team of 380+ people representing over 60 nationalities, united by a passion for transforming the future of short-term rentals.

⭐️ Role Overview
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.

⭐ 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, ...).
