ppbDecima builds and evolves complex commerce systems that power integral brands. /b /p pWe’re looking for a Lead Backend Engineer who operates at an architect level but stays deeply hands‑on. /p pMost 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. /p pThis requires a different mindset: understanding existing systems deeply, making safe and well‑reasoned changes, and balancing long‑term architecture with real‑world constraints. /p pYou’ll be the person engineers rely on when changes are risky, and the one clients trust when stability matters as much as progress. /p h3Role Overview /h3 ul liIn this role, you will lead the evolution of existing enterprise Adobe Commerce Cloud platforms — introducing new features, integrations, and improvements while preserving system stability /li liYou’ll work within complex, already built ecosystems, making thoughtful architectural decisions that respect existing constraints and minimize risk /li liThis is a hands‑on role — you’ll actively contribute to implementation, review critical code, and ensure that every change is safe, scalable,
