Decima builds and evolves complex commerce systems that power global brands. We’re looking for a Lead Backend Engineer who operates at an architect level but stays deeply hands-on.
Most of our clients already have large, business-critical Adobe Commerce (Magento 2) platforms in place. In this role, you will lead the evolution of existing enterprise Adobe Commerce Cloud platforms — introducing new features, integrations, and improvements while preserving system stability.
Own architecture decisions within existing Magento 2 systems — balancing improvement with stability.
Lead complex integrations with ERP, PIM, OMS, CRM systems within existing environments.
Review critical code changes with a focus on safety, performance, and maintainability.
8+ years of professional software development experience.
~5+ years of hands‑on Magento 2 / Adobe Commerce Cloud development.
~ Deep understanding of Magento 2 architecture - DI, plugins, service contracts,



extension attributes, event/observer patterns.
~ Proven experience designing integrations with ERP, OMS, or PIM systems (SAP, NetSuite, Akeneo, or similar).
~ Strong PHP engineering skills, OOP, and design patterns.
~ Experience with APIs (REST, GraphQL) and service‑oriented architecture.
~ Experience with cloud environments and DevOps (CI/CD, Docker, AWS/GCP, Magento Cloud).
