Sr. WordPress Engineer

Experience: 7+ Years

Job Type: Full-time (Remote)

Location: Europe

About the Role

We are looking for a highly skilled Senior WordPress Developer with deep expertise in custom WordPress development, performance engineering, and modern web technologies.

The ideal candidate is a problem solver, strong communicator, and hands-on engineer who understands the WordPress ecosystem deeply — from Gutenberg block development to backend architecture, APIs, caching, cloud hosting, and DevOps workflows.

About the Company 

Our client is a global, enterprise-focused WordPress engineering partner helping well-known brands and high-traffic organizations build, modernize, and scale mission-critical WordPress platforms. They deliver custom development at scale (themes, plugins, Gutenberg/React block libraries), complex integrations, and performance/security work for sites serving millions of users. The team operates in a mature, distributed setup with strong engineering standards, code reviews, and ownership culture. If you enjoy solving real production problems — architecture, performance, reliability, and developer experience — this is an environment where WordPress is treated as serious engineering, not just website building.

4. Collaboration & Communication

• Work closely with solution architects, designers, and project managers to ensure flawless execution of features.

5. Continuous Improvement

• Stay updated with the latest WordPress advancements, PHP frameworks, performance techniques, and emerging tools.
