We are looking for a Senior Fullstack WordPress Developer to join one of our high-growth client teams. In this role, you will be the technical architect for complex web applications, pushing the boundaries of what WordPress can deliver in an enterprise environment. You aren't just customizing themes; you are building bespoke Gutenberg blocks, managing Headless WordPress architectures via WPGraphQL, and optimizing high-traffic database schemas. You will lead the development lifecycle from custom backend logic to high-performance, interactive frontend components, ensuring every line of code is scalable, secure, and maintainable.
Responsibilities
- Lead the development of custom, end-to-end WordPress solutions, from backend logic to interactive frontend components.
- Build advanced, user-friendly block patterns and custom blocks that empower content editors.
- Support the transition from legacy "monolithic" WordPress setups to modern block-based or headless architectures.
- Optimize server-side and client-side performance to ensure lightning-fast load times for high-traffic sites.
- Conduct thorough code reviews, promoting a culture of technical excellence.
Requirements
- Expert-level knowledge of PHP 8.x and the WordPress core (Hooks, Filters, REST API, and WP-CLI).
- Deep experience with React.js, specifically for building custom Gutenberg blocks and dynamic editor interfaces.
- Proven ability to build custom themes (FSE/Block-based) and sophisticated plugins from scratch without the bloat of page builders.
- Expert-level understanding of REST API and WPGraphQL for decoupled/headless setups and third-party integrations.
- Solid experience with MySQL optimization, object caching (Redis/Memcached), and achieving perfect Core Web Vitals.
- Proficiency with Webpack/Vite, Composer, and Git-based deployment workflows.
- A commitment to WordPress Coding Standards and building accessible (WCAG compliant) user experiences.
- Located in CET timezone (+/- 3 hours), we are unable to consider applications from candidates in other time zones.
- Nice-to-have skills:
- Experience with the Roots stack (Sage, Bedrock, Trellis).
- Familiarity with Next.js or Gatsby for headless frontend implementations.
- Advanced knowledge of WooCommerce at the enterprise level.
- Experience with unit testing frameworks (PHPUnit) and E2E testing (Playwright).
