Job Description:
Seeking a PHP Developer to support a recently acquired payment management platform by maintaining and enhancing an existing production application. This role will focus on improving application stability, implementing ADA accessibility updates, and migrating payment processing from a third-party provider to the client's internal platform. The application itself is straightforward, but the codebase contains technical debt, duplicated client-specific pages, and limited development infrastructure. The ideal candidate enjoys improving existing systems, working independently, and bringing structure to evolving development processes.

Day-to-Day Responsibilities:

  • Maintain and enhance an existing production PHP web application
  • Refactor and improve a legacy codebase with duplicated client-specific pages
  • Optimize MariaDB (or MySQL) databases by writing complex SQL queries and improving database performance
  • Implement ADA accessibility improvements, including UI updates, color schemes, fonts, and usability enhancements
  • Support the migration of payment processing from a third-party platform to the client's internal payment platform
  • Troubleshoot production issues, investigate defects, and deploy fixes with minimal oversight
  • Consume REST APIs and support backend integrations
  • Work directly with the Hiring Manager to improve source control, development processes, and overall application stability
  • Complete development work through Jira tickets while participating in daily Agile standups
  • Write clean, maintainable, and well-documented code while reducing technical debt where appropriate

Minimum Requirements:

  • 3–5 years of professional PHP development experience
  • Strong experience with MariaDB (preferred) or MySQL database development and optimization
  • Experience maintaining, troubleshooting, and enhancing production or legacy web applications
  • Experience writing complex SQL queries and optimizing database performance
  • Experience consuming REST APIs and supporting backend integrations
  • Experience with Git and version control
  • Strong troubleshooting, debugging, and problem-solving skills
  • Ability to work independently with minimal direction and take ownership of projects
  • Experience working in legacy or poorly structured codebases with technical debt
  • Strong communication skills with both technical and non-technical stakeholders
Preferred Qualifications:
  • Experience with Laravel or another modern PHP framework
  • Linux environment experience
  • JavaScript, HTML, and CSS experience
  • Experience working in Agile development environments
  • Experience supporting payment processing or financial applications
  • Experience implementing accessibility (ADA/WCAG) improvements
