Are you a backend engineer with a knack for building complex, scalable systems? Join our team as a Senior Backend Engineer, where you’ll craft innovative features, optimize large-scale distributed systems, and shape the future of our core product.

  • Actively contribute to all phases of the software development lifecycle.
  • Does this sound like you?

  • 5+ years of backend development experience in PHP.
  • 2+ years working with Laravel to build enterprise-level applications—or equivalent experience with Symfony and a strong motivation to learn Laravel.
  • Expertise in distributed systems, scalable services, and RESTful APIs.
  • Familiarity with event-driven architecture and messaging systems (e.g., queues, pub/sub).
  • Strong SQL/NoSQL knowledge and caching strategies.
  • Proficiency in OOP, SOLID principles, and design patterns.
  • Experience with AWS services (e.g., EC2, Lambda, SQS, Aurora, DynamoDB).
  • Experience with monitoring tools like Datadog and Prometheus.
  • Hands-on containerization skills with Docker.
  • Fluent English communication skills.
