Senior PHP Engineer

OneTouch is seeking a senior PHP software engineer to build and modernize customer-critical capabilities in the OneTouch platform by incrementally migrating legacy PHP into well-structured Laravel services, improving reliability, performance, and maintainability in a multi-tenant environment. In addition, this role will be responsible for feature development and working as a lead developer for a full stack scrum team focused on specific platform functions.

Key Responsibilities:

  • Deliver features in Laravel while progressively extracting/rewriting legacy PHP into modular components.
