Role Overview

We are looking for a Senior Developer who lives and breathes backend engineering to join our core development team. Your primary mission is to build and maintain the robust server-side logic that powers our platforms. You are a master of PHP and Symfony, but you aren’t afraid to jump into a React component or adjust a Node service when the mission requires it. You will work alongside a talented team of engineers to ensure our applications are secure, performant, and scalable.


Key Responsibilities

Core Backend Engineering (Primary Focus):

  • Symfony Development: Build and maintain complex backend services using PHP 8.x and Symfony, ensuring code is clean, modular, and well-tested.
  • Data Layer Execution: Manage and optimize performance and schema design for our MySQLand MongoDB databases.
  • API Construction: Develop high-throughput RESTful APIs that serve as the backbone for our internal and external integrations.
  • Logic & Runtime: Work with Node.js for specialized microservices, real-time data processing, or internal tooling.

Frontend & Integration (The “Plus”):

  • Full-Stack Collaboration: Partner with UI specialists to integrate backend logic with React frontends.
  • Component Maintenance: Modify or build React components to ensure end-to-end feature delivery.
  • JS Ecosystem: Use your JavaScript knowledge to ensure seamless data flow between server-side services and the browser.

Performance & Reliability:

  • Optimization: Identify and resolve bottlenecks in the backend, from complex SQL queries to inefficient PHP processing.
  • Testing: Maintain a rigorous testing culture, writing unit and integration tests (PHPUnit) to ensure platform stability.
  • Security: Follow “security-by-design” principles across the stack, focusing on data protection and secure authentication.

Qualifications

  • Experience: 5+ years of professional backend-heavy development within a team environment.
  • Mastery: Deep expertise in PHP 8, Symfony, and MySQL.
  • Database Variety: Hands-on experience working with MongoDB in production.
  • Full-Stack Competency: Functional proficiency in React and Node.js.
  • Tooling: Proficient with Git, Docker, and working within modern CI/CD pipelines.
