1189 Senior WordPress Developer

Intetics Inc., a leading American technology company specializing in custom software application development, distributed professional teams creation, software product quality assessment, and “all-things-digital” solutions, is looking for a Senior WordPress Developer to join its innovative team.

Build and maintain custom themes, plugins, and Gutenberg blocks across a portfolio of high-traffic, multilingual WordPress sites

Build and consume REST APIs and integrations with internal and third-party systems

Take part in code reviews, CI/CD improvements, and engineering standards initiatives

Collaborate with product, marketing, SEO, content, and QA teams on new features and site improvements

Document technical decisions and contribute to engineering best practices

Ensure software development best practices and timely product delivery

We're looking for a Senior WordPress Developer who treats WordPress as a modern engineering platform rather than a traditional CMS.
