PHP Backend Developer

Role Overview

• As a PHP developer you are part of our backend team and work together with colleagues from other software areas to further develop our platform.
• You design new features on our existing Yii-based site, contribute to our new Symfony developments and actively help migrate the monolith to a service-oriented architecture.
• You further develop existing Transfermarkt functions and initiate new features — both in the monolith and in the new Symfony stack.
• You build robust REST APIs that connect our web and app projects.
• You coordinate closely with stakeholders, e.g. on API design or the integration of external services.
• You work in a growing system that handles many millions of requests per day — performance, scalability and clean architecture are the focus.
• You build it, you run it: your interest goes beyond software development; you are also interested in how the application behaves in production, and how it can be monitored and improved.
• You develop in an agile Scrum process in two-week sprints and actively participate in reviews, retrospectives and technical improvements.

Requirements

• You have several years of experience developing with PHP — ideally with Symfony, Yii or comparable frameworks.
• You are familiar with REST APIs and classic MVC architecture and are open to transitioning to a modern service-based environment.
• You have an understanding of performance, scalability and maintainability of large web applications.
• You are interested in close technical coordination with microservice and frontend colleagues.
• You enjoy working in a team, actively participate in code reviews and take responsibility for your areas.
• Very good German language skills (at least C1) are required.

Tech Stack

• PHP
• Symfony
