Role Description 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. Your role is not to rebuild them from scratch — but to carefully evolve, extend, and improve them without breaking what already works. This requires a different mindset: understanding existing systems deeply, making safe and well-reasoned changes, and balancing long-term architecture with real-world constraints. You’ll be the person engineers rely on when changes are risky, and the one clients trust when stability matters as much as progress. 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. You’ll work within complex, already-built ecosystems, making thoughtful architectural decisions that respect existing constraints and minimize risk. This is a hands-on role — you’ll actively contribute to implementation, review critical code, and ensure that every change is safe, scalable, and aligned with the overall system design. Responsibilities - Own architecture decisions within existing Magento 2 systems — balancing improvement with stability. - Analyze and deeply understand legacy codebases and current system behavior before making changes. - Design extensions and integrations that fit cleanly into existing architecture. - Ensure backward compatibility and minimize regression risk in all changes. - Lead complex integrations with ERP, PIM, OMS, CRM systems within existing environments. - Review critical code changes with a focus on safety, performance, and maintainability. - Identify architectural risks and propose safe, incremental improvements. - Guide the team in making thoughtful, non-breaking changes. - Participate in discovery and pre-sales — assessing existing systems and proposing realistic solutions. - Document decisions with clear reasoning and trade-offs. Qualifications - 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). - Prior experience in a lead or architect-level role with ownership of technical decisions. - Strong communication skills - able to explain technical decisions clearly. Requirements - Experience working with large, existing Magento 2 codebases (not only greenfield projects). - Strong ability to understand and safely modify legacy systems. - Experience delivering improvements without full rewrites. - Ability to balance ideal architecture with real-world constraints. - Strong debugging and root-cause analysis skills in complex systems. - Experience working in environments where system stability is critical. Benefits - Work on enterprise commerce systems powering global brands. - Real architectural ownership. - Supportive, transparent, and collaborative team culture. - Ongoing professional development and learning support.
