We are hiring a Senior PHP/Laravel Engineer to join our R&D. Our core systems power seat inventory, pricing, and ticketing logic across hundreds of operators.

In this role you will:

• Architect, code, and ship backend features in Laravel in fast-paced sprint cycles.
• Lead refactoring of legacy PHP into modular, service-oriented Laravel codebases.
• Design robust REST and GraphQL APIs consumed by web and mobile clients.
• Write and maintain integration and unit tests with PHPUnit or Pest.
• Tune SQL queries, caching layers, and job queues for maximum performance.
• Contribute to Docker containers, CI pipelines, and deployment workflows.
• Collaborate with QA, FE, and product on defining and delivering technical requirements.
