Lead the architecture and hands-on evolution of enterprise Adobe Commerce and Magento 2 platforms. Design safe extensions and integrations with ERP, PIM, OMS, and CRM systems; review critical code; maintain backward compatibility; reduce regression risk; diagnose complex issues; and guide engineers through incremental improvements. The role also includes technical discovery, pre-sales assessments, architectural documentation, and communication of technical trade-offs.
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.

Role Overview
- 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.
Requirements
- 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.
- 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. В
