Decima builds and evolves complex commerce systems that power integral 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.
