PHP Developer

Permanent employee, Full-time · Remote (Poland)

Das erwartet dich

We are looking for a PHP Developer to support the maintenance, improvement, and stabilization of existing web applications. This is not a greenfield role — the primary focus is working with mature and legacy systems, resolving production issues, improving code quality, and delivering incremental enhancements.

You will contribute to extending system lifespan, reducing technical debt, and improving maintainability over time. This position is best suited for developers who are comfortable working with legacy code, understand real-world system constraints, and have experience gradually improving existing solutions rather than building from scratch.

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
Support gradual modernization of outdated components
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
