We are looking for a PHP Developer to support the maintenance, improvement, and stabilization of existing web applications.

This role is for developers who:
Have commercial experience working with PHP in production systems
Have worked with legacy or long-lived codebases
Are comfortable navigating large or complex applications
Understand the balance between refactoring and delivering business value
Prefer practical engineering over “perfect from scratch” solutions
Are detail-oriented and patient when improving existing systems
Your Responsibilities
Maintain and enhance existing PHP-based applications
Analyze and work with legacy codebases and system architecture
Identify, troubleshoot, and fix bugs and performance issues
Refactor legacy code to improve readability, stability, and maintainability
Implement new features within existing system constraints

Write clean, structured code aligned with OOP and Clean Code practices
Collaborate with QA, DevOps, and Product teams to ensure stable releases
Write and maintain automated tests where feasible
Contribute to technical documentation
Participate in code reviews and technical discussions
