About The Position

Our client - an international media organization - is looking for a Senior Full-Stack Engineer PHP - WordPress to evolve a large-scale, mission-critical publishing platform used by millions of readers globally. This is a senior software engineering position, not a traditional WordPress admin role. You will work across PHP, modern JavaScript/React, and the WordPress platform as a technical framework—designing scalable systems, writing clean, well-tested code, and contributing to architecture and engineering standards. This role is designed to attract Senior Engineers with strong fundamentals (SOLID, testing, design patterns, architecture), robust experience with GIT, and who also have meaningful experience building custom functionality within large WordPress platforms.

Requirements

Senior Engineering Fundamentals
5+ years of professional full-stack engineering experience (PHP + Modern JS).
Strong understanding of SOLID principles, design patterns, and scalable architecture.
Ability to design systems, reason about trade-offs, and communicate architectural decisions.
Testing & Software Quality (Non-Negotiable)
Proven, hands-on experience with unit testing across PHP and JavaScript.
Experience with TDD or disciplined testing workflows.
Strong Git proficiency with modern collaborative workflows.
WordPress Platform Specialization
Significant experience integrating custom, large-scale functionality into WordPress.
Understanding of WordPress architecture (hooks, filters, custom post types, plugin architecture, extending core).
Experience using WordPress as a technical foundation, not a CMS assembly tool.
Frontend Engineering Depth
Modern JavaScript (ES6+) experience, including hooks and state management.
Solid HTML/CSS fundamentals and ability to ship production-ready UI components.
Collaboration & Ownership
Excellent communication skills, especially in distributed/remote settings.
Strong ownership mindset—delivering features end-to-end and supporting them post-release.

Nice To Haves

Gutenberg block development.
Strong React experience.
Familiarity with cloud platforms (GCP, Azure, AWS).
Experience with Docker, CI/CD tooling, and DevOps-oriented workflows.
Node.js/GraphQL exposure.
Experience using AI-assisted development tools (Copilot, prompt engineering).

Responsibilities

Build and maintain complex, large-scale features across PHP, React, and WordPress.
Develop custom platform functionality beyond plugin/theming layers.
Contribute to system architecture, design discussions, and technical decision-making.
Improve the performance, scalability, and reliability of a high-traffic publishing ecosystem.
Deliver end-to-end product features using PHP, React, HTML, CSS, and supporting tooling.
Write robust unit tests (PHPUnit/Jest) to uphold engineering and quality standards.
Review code, mentor peers, and help elevate engineering practices across teams.
Collaborate closely with internal and vendor teams in a fast-paced environment, balancing multiple priorities.
