Hiring a WordPress plugin developer for an agency project means finding someone who understands agency workflows, client expectations, and scalable, maintainable code. Start by being clear about scope: is this a custom plugin, white‑label feature set, or ongoing maintenance of existing plugins? That clarity makes it easier to evaluate candidates and compare proposals fairly.

Steps to hire

  1. Define scope and deliverables. List features, integrations, expected compatibility (PHP, WP versions), and delivery milestones.
  2. Evaluate portfolio and references. Look for plugins published in client projects, evidence of code quality, and agency-focused work.
  3. Assess technical skills. Check experience with hooks, REST API, custom post types, security best practices, and automated testing.
  4. Test communication and process. Confirm they can work with your project management, git workflow, and client approval cycles.
  5. Agree on licensing, support, and SLAs. Clarify ownership, updates, bug fixes, and response times after launch.

Core skills to look for:

  • Strong PHP, JavaScript (ES6+), and WordPress API knowledge
  • Experience with Composer, PHPUnit, and deployment pipelines
  • Security-aware coding and performance optimization
  • Clear documentation and versioned releases
