Vacatia is reinventing the vacation ownership and rental experience across discovery, booking, and stay. Our engineering team builds the platforms that power resort operations, guest experiences, and data-driven decision making across our growing hospitality ecosystem.

We're looking for a Senior Software Engineer with deep PHP and Symfony experience to help design and build scalable, high-performance applications that support Vacatia's rapidly evolving technology platform. This role is ideal for someone who enjoys solving complex technical challenges in an established, multi-application codebase, optimizing performance across systems, and contributing to thoughtful software architecture.

• Design and build scalable web applications using PHP and the Symfony Framework
• Architect modular systems using modern software design patterns and Symfony best practices
• Navigate and contribute to large, established multi-application codebases
• Develop and maintain robust APIs and integrations with internal services and third-party platforms
• Design and distribute reusable internal SDK client libraries with dependency injection, automatic token management, caching, and broad version compatibility
• Integrate across heterogeneous third-party platforms using varied auth protocols and change data capture (CDC) event streams
• Build event-driven integration pipelines with idempotency guarantees and webhook security hardening
• Optimize performance across the application stack, including database queries, caching, distributed locking, and backend logic
• Collaborate with product, frontend, and data teams to deliver seamless end-to-end features
• Contribute to code reviews, engineering standards, and technical architecture decisions
• Mentor engineers and help foster a culture of clean, maintainable, well-tested code

What You Bring

• 5+ years of professional PHP development experience
• Strong expertise with the Symfony Framework
• Deep understanding of object-oriented programming, design patterns, and service-oriented architecture
• Experience building APIs and integrating external services, including familiarity with OAuth2, JWT, and SCIM authentication patterns
• Strong SQL skills with MySQL or PostgreSQL
• Experience with Git, CI/CD pipelines, and containerization tools like Docker
• Ability to troubleshoot complex performance issues across distributed, multi-service architectures
• Strong testing discipline — unit tests, functional and integration tests against live systems, and CI pipeline configuration

Bonus

• Experience with ETL pipeline design, legacy data migration, or cloud data warehouse platforms (e.g., Snowflake)
• Experience with AWS services in integration and observability roles (e.g., EventBridge, DynamoDB, CloudWatch)
• Experience in hospitality, travel, or marketplace platforms
• Experience supporting high-traffic consumer web applications
