Location: Cluj-Napoca, Romania Workplace: hybrid About Welo Global  Welo Global is a leader in multilingual AI, technology, and content solutions serving over 2,000 clients in 300 languages. The company combines globally scaled multilingual infrastructure, including a network of over 500,000 linguists and domain experts, with advanced NLP, computational linguistics, and best-in-class compliance backed by seven ISO certifications. Welo Global’s five brands—Welocalize (multilingual content and localization services for global enterprises), Park IP (intellectual property and patent translation services for law firms and corporate legal teams), Welo Life Sciences (regulated language and compliance-aligned content solutions for pharmaceutical, biotech, and medical device organizations), Adapt (multilingual performance-led digital marketing agency), and Welo Data (multilingual data generation, evaluation, and human data infrastructure for AI systems)—serve distinct customer segments with purpose-built expertise, fit-for-purpose solutions, and supporting technology. weloglobal.com  Overview Welocalize is looking for a WordPress Developer to bring website maintenance and backend development in-house across our six brand sites: welocalize.com, welodata.ai, parkip.com, adaptworldwide.com, welolifesciences.com, and weloglobal.com. This work currently sits with an outside agency and we're looking for someone who can own it internally — with faster turnaround, better institutional knowledge, and closer collaboration with our Marketing and front-end teams. The platform is a WordPress Multisite environment. You'll work alongside an internal front-end developer who handles content management, page building, and UX — your focus is the backend: keeping the platform healthy, building custom functionality, and managing deployments.   Job Reference: #LI-JC1 Key Responsibilities Keep all six brand sites up to date — security patches, plugin updates, and core updates on a routine and emergency basis. Monitor site health, uptime, and performance; coordinate with our hosting provider (Pantheon) on backups, restores, and incident response. Serve as the internal point of contact for WordPress-related technical requests, triaging and prioritising work coming from Marketing and other teams. Handle day-to-day development requests: bug fixes, small feature builds, and plugin configuration. Build and maintain custom Gutenberg blocks (PHP + JS) and handle PHP theme modifications as needed. Manage the Webpack-based build process and SCSS structure for the shared theme. Own the deployment pipeline — Git-based deployments across Dev, Test, and Live on Pantheon — and review front-end changes before they go live. Set up and configure hosting environments, domain onboarding, and SSL on Pantheon. Maintain third-party integrations — forms, GTM, translation connectors, and APIs. Respond to critical incidents: site down, data loss, or security breach across any brand site. Conduct accessibility technical reviews (axe DevTools, screen reader testing) and implement approved fixes. Build and maintain internal technical documentation — this role replaces an outside agency, so knowledge retention matters from day one. Requirements Education/Experience 3+ years of WordPress development experience, ideally including Multisite environments. Solid PHP skills and hands-on experience with Gutenberg block development (PHP + JS). Comfortable with SCSS/CSS, BEM methodology, and a build tool such as Webpack. Familiar with WordPress security fundamentals — patching, hardening, vulnerability response. Experience with Git and staging/production deployment workflows. Good communicator — you'll work closely with Marketing, front-end, and IT and need to translate technical issues clearly. Additional Qualifications Experience with Pantheon or a comparable managed WordPress hosting platform. Familiarity with multilingual WordPress setups (MultilingualPress, WPML, or similar). Experience with Composer for PHP dependency management. Working knowledge of DNS, domain configuration, and SSL basics. Exposure to translation management integrations (Phrase, Smartling, or similar).
