Company Description

SCAYLE stands for innovation, international collaboration, and a strong focus on data. We believe that stepping outside of our comfort zone and making bold decisions is key to growing both professionally and personally.

What drives us is the shared motivation to make an impact and actively shape the future of eCommerce.

  • Build event-driven pipelines using AWS SNS/SQS for asynchronous payment, order, and inventory processing
  • Optimize database queries (MySQL/PostgreSQL) and Redis cache layers to handle massive traffic spikes smoothly
  • Write automated tests, review pull requests, and advocate for sustainable architecture and clean code
  • Collaborate daily with product, QA, and DevOps teams to deliver high-impact improvements in short sprints
  • Troubleshoot complex technical issues and balance long-term code health with pragmatic product delivery

Qualifications

  • 6+ years of backend development experience with senior-level ownership
  • PHP 8.x mastery using Laravel, Symfony, or modern enterprise frameworks
  • Relational database & caching skills (MySQL, PostgreSQL, Redis)
  • API & microservice design with OpenAPI/Swagger standards
  • Asynchronous processing experience using SNS/SQS
  • Containerization & CI/CD workflow knowledge (Docker, Git, GitLab CI)
  • Fluent English with transparent, solution-oriented communication

 

Nice To Have:

  • Experience with cloud platforms, Kubernetes, and application observability/monitoring tools.
