About this role

The role covers web application design, development, maintenance, technology selection, UX improvements, release-effect measurement and continued improvement.
The engineer is expected to identify and articulate user and community problems using data and user feedback, then participate throughout the product development process from planning and implementation to post-release validation. Responsibilities also include proposing new features, improving development experience in areas such as CI/CD and design systems, and leading projects through project management.
The backend environment is mainly PHP and MySQL, with selected cloud services such as Google Cloud.
